What Is Sexually Transmitted Disease (STD)​?​​

Sexually Transmitted Diseases (STDs) can be caused by bacteria, viruses, or parasites, and include common infections such as chlamydia, gonorrhoea, syphilis, HIV/AIDS, and genital herpes. Anyone who is sexually active, regardless of age, gender, or sexual orientation, can be at risk of contracting an STD. Hence, STD testing is important for early detection, even if you have no symptoms. Left untreated, STDs can lead to serious health complications.

At Elyon Clinic, we offer rapid STD testing, with results available within 20 minutes, providing quick answers and peace of mind. Screening methods are tailored to individual risk factors, sexual practices, and symptoms. Tests may include urine tests, blood tests (via arm draw or finger prick), oral or genital swabs, or swabs from discharge or cell samples.

Incidence rate by STIs in Singapore

STIs Incidence rate per 100,000 people
Chlamydia 26.9
Genital warts 15.3
Gonorrhoea 11.8
Syphilis 11.2
Genital herpes 6.9

According to the data from Communicable Diseases Agency (CDA), Chlamydia remains the most commonly reported Sexually Transmitted Infections (STI) in Singapore, with an incidence rate of 26.9 per 100,000 people. Other prevalent infections include genital warts (15.3), gonorrhoea (11.8), syphilis (11.2), and genital herpes (6.9).

These figures highlight that STIs continue to pose a public health concern, and many of these infections are treatable or manageable if detected early. This makes regular testing especially important for those with new or multiple sexual partners.

What are some of the symptoms of STDs/STIs?

  • Urethral or vaginal discharge: A thick, watery, or discoloured discharge from the penis, vagina, or anus may be a sign of infection. This can sometimes be accompanied by an unpleasant odour.
  • Painful urination: A burning or stinging sensation during urination, often described as sharp or itchy, is a common symptom of several STIs.
  • Itch or pain in the urethra or vagina: Persistent itching, tingling, or irritation around the genital or anal areas could indicate an infection or skin-related STI.
  • Rashes, sores, or blisters on the genitalia: Open sores, fluid-filled blisters, or ulcers may appear on or around the genitalia, anus, or mouth. These can be painless or painful, depending on the type of infection. Flat or raised rashes may also develop on the skin, especially in the genital area, thighs, or even palms and soles, depending on the STI.
  • Lumps or growths on the penis or vagina: Small warts, bumps, or growths on the penis, vagina, or anus may be a symptom of infections like HPV (Human Papillomavirus).
  • Pain during sexual intercourse: Discomfort, soreness, or pain during or after sex, especially in women, can be associated with pelvic infections or inflammation caused by STIs.
  • Pain, aching, swelling, or heaviness in the testicles: Aching, heaviness, or visible swelling in the testicles or lower abdomen may point to infections like chlamydia, gonorrhoea, or epididymitis.
  • Abnormal bleeding: Unexpected vaginal bleeding, such as spotting between periods or bleeding after sex, may be linked to infections that affect the cervix or uterus.
  • Flu-like symptoms: Some STIs, including HIV or syphilis, can cause general symptoms such as fever, chills, sore throat, fatigue, muscle aches, or swollen lymph nodes, particularly in the neck, armpits, or groin.

Many STDs can be asymptomatic, meaning they don’t show noticeable signs, especially in the early stages. If you’re experiencing any of these symptoms or feeling unsure, it’s important to prioritise your health by consulting a doctor.

Why is STD Screening Important?​

Our Testing Process

1. Consultation

We provide a safe, respectful, and non-judgmental environment during every consultation. Your comfort and privacy are our priorities. During this session, our doctor will take time to understand your concerns and guide you through the process with care. An honest and detailed account of your sexual history will help us recommend the most appropriate tests for you.

2. Diagnosis

A proper diagnosis begins with a comprehensive review of your physical, sexual, and psychosocial health. This includes open discussion about lifestyle habits, such as substance use, that may increase your risk. Your doctor will assess this information to determine which laboratory tests are necessary for the accurate detection of any infections.

3. Tests and Treatments

Based on your individual risk profile and symptoms, we may recommend a full STD or STI screening. Our clinic offers both targeted and comprehensive testing options to suit your needs. Should results indicate an infection, our doctor will discuss your treatment plan, offer preventive advice, and provide prescriptions where needed; all handled discreetly and professionally.

What do I need to prepare before going for an STD consultation or test?

Before Your Visit

  • Avoid urinating 1–2 hours before the test, which is especially important for urine-based tests.
  • Do not clean your genital area before providing a urine sample, unless instructed otherwise.
  • If menstruating, wait until after your period ends to take the test.
  • Bring a valid photo ID for registration purposes.
  • Fasting is not required, so you may eat and drink as usual prior to your appointment.

During the Consultation

  • Be open about your sexual history and any symptoms you may be experiencing. This information helps your doctor determine the most suitable tests.
  • Consultations are strictly confidential and conducted in a non-judgmental setting.

When Providing a Sample

  • Collect the first part of your urine stream into the sample cup.
  • Follow any specific instructions given by your healthcare provider carefully.

Emotional Preparation

It’s normal to feel nervous. Getting tested is a responsible step towards protecting your health and your partner’s. Our doctors are here to support you, not judge you.

Common STD Syndromes and Complications​

  • Acquired Immunodeficiency Syndrome (AIDS)
  • Ano-genital lumps
  • Ano-genital ulcers
  • Ano-rectal syndromes
  • Acute arthritis
  • Pelvic inflammatory disease (PID)
  • Female infertility and ectopic pregnancy
  • Fetal and neonatal infections
  • Complications of pregnancy and delivery such as spontaneous abortion, premature labour, and premature rupture of membranes
  • Neoplasia such as cervical carcinoma and dysplasia
  • Human papillomavirus infection and genital warts
  • Female lower genital tract infection such as cervicitis and urethritis
  • Male urethritis
  • Viral hepatitis
  • Tertiary syphilis and neurosyphilis
  • Epididymo-orchitis
  • Molluscum contagiosum
  • Skin rash genital or generalised
  • Vaginal discharge

Women face a higher risk of contracting STDs, as transmission tends to be more efficient from men to women. Additionally, many infections in women may present without noticeable symptoms, allowing them to go undetected. This silent progression increases the likelihood of serious complications such as infertility, cervical cancer, and pregnancy-related issues. As such, regular STD screening in Singapore plays an essential role in early detection, timely treatment, and safeguarding long-term reproductive health.

Frequently Asked Questions on STDs

If you’ve recently had a possible exposure, the timing of your test matters because every infection has its own window period. This is the time your body needs before a test can reliably detect an infection.

As a general guide:

  • HIV (4th gen test): Usually accurate from 14 days, with the most reliable results at 28 days.
  • Chlamydia and Gonorrhoea: Can typically be detected from 7 to 14 days after exposure.
  • Syphilis: Usually detectable from 10 to 90 days, though many people test accurately from 3 to 4 weeks.
  • Hepatitis B and C: Usually show up from 3 to 6 weeks onwards.
  • Herpes (HSV-1 and HSV-2): Typically accurate from 4 to 6 weeks after exposure, though testing is usually most reliable when symptoms, such as blisters or sores, are present.

If you’ve had sex without a condom, engaged with more than one partner, shared injection equipment, or feel you may have been exposed in any way, it’s wise to speak with a doctor and get tested.

If you’re sexually active, a good general routine is at least once a year, even if you feel well and have no symptoms.

If you’re at higher risk, such as having multiple partners, having sex without protection, being newly sexually active with a new partner, or engaging in higher-risk behaviours, consider testing every 3 to 6 months. This helps pick up silent infections early and protects both you and your partners.

Yes. Many STIs do not cause symptoms at all, especially in the early stages. It’s very common for people to feel perfectly fine and still carry an infection.

When symptoms do appear, they may include things like:

  • Unusual vaginal or penile discharge
  • Pain or burning when urinating
  • Genital sores, ulcers, or blisters
  • Itching or irritation
  • Lower abdominal or pelvic pain
  • Bleeding between periods (for women)

Because not everyone gets these warning signs, regular testing is still important. If you’ve had any form of sexual contact, it’s safer to check.

If you and your partner have been in a committed, long-term, and mutually monogamous relationship where neither of you has had any other sexual partners since your last negative test, then the need for frequent routine screening is significantly reduced.

However, getting tested is highly recommended in the following scenarios:

  • At the start of the relationship: Both you and your partner should be tested before you stop using barrier methods (like condoms) to confirm that neither of you is unknowingly carrying a pre-existing infection.
  • If either partner was not tested initially: If you did not receive a full screening before becoming exclusive, testing is advised to establish a baseline of good health.
  • If either partner has had any outside sexual contact: Any change in the monogamous status warrants immediate testing for the partner who had the outside contact, and subsequently for the other partner.

Yes, a person who has not had vaginal intercourse can absolutely contract an STD. STDs can spread through several avenues, including:

  • Oral or anal sex, which are common routes of transmission for infections like Chlamydia, Gonorrhea, and Herpes.
  • Direct skin-to-skin contact with the infected area, such as with Genital Herpes or Human Papillomavirus (HPV).
  • The sharing of infected needles used for drug injection or tattooing.
  • Contact with infected blood or fluids in other non-sexual contexts.

Therefore, anyone engaging in any form of sexual intimacy is at risk and should consider testing.

Yes, you are still at risk of contracting another STD. Having one infection does not provide immunity against others. For example, if a person has Herpes, they can still contract Chlamydia, Gonorrhea, or HIV.

In fact, having an STD can sometimes increase your vulnerability to contracting a different infection. Certain infections, such as those that cause sores (like Syphilis or Herpes), can create breaks in the skin, which makes it easier for viruses like HIV to enter the body. It is important to continue practicing safe sexual behaviours even while managing a current infection.

The tests you should receive are highly individualised and depend entirely on your sexual activity, behaviours, and risk factors. A doctor will work with you to recommend a screening panel that targets your specific needs.

Here are our general recommendations based on common scenarios:

  • For people with lower risk or routine screening needs

 A basic panel is usually enough. This typically includes screening for HIV, Syphilis, Chlamydia, and Gonorrhoea. At Elyon Clinic, the closest match to this is the STD Basic I test, which covers HIV, Syphilis, and Hepatitis B. If you would also like to include Chlamydia and Gonorrhoea, you can add the Chlamydia and Gonococcal PCR test for a more complete routine check.

  • For individuals with higher risk, new symptoms, multiple partners, or recent exposure

 A comprehensive panel offers a wider and more detailed assessment. This includes HIV, Syphilis, Hepatitis A, B, and C, Herpes Simplex Virus Types I and II, and a full range of urine or swab tests for common genital infections. The most suitable options at Elyon Clinic are the Comprehensive Female STD Test or the Comprehensive Male STD Test, both of which cover the broadest set of infections in a single visit.

  • If you have engaged in oral or anal sex

Some infections may be present in the throat or rectum without showing up in a urine test. If this applies to you, request a site-specific swab such as the Chlamydia and Gonococcal PCR throat swab or rectal swab. You may also opt for the STI-7 Multiplex PCR, which screens for several organisms using swab or urine samples. Our comprehensive packages for males and females already include multi-site testing for better accuracy.

  • Women under 25

 If you are under 25, yearly screening for Chlamydia and Gonorrhoea is recommended. You can choose the Urinary (Female) Urethritis and Vaginitis STD Test, which checks for these infections along with other common vaginal pathogens, or select the Chlamydia and Gonococcal PCR test if you prefer targeted screening.

  • Pregnant women

 Testing early in pregnancy helps protect both mother and baby. We recommend screening for HIV, Hepatitis B and C, and Syphilis. The simplest option at Elyon Clinic is the STD Basic II panel, which includes all four tests. Individual tests such as the SD Bioline HIV Duo Test or Hepatitis panels are also available if targeted follow up is required.

  • If you are unsure which package suits you best, our doctors will advise you during the consultation and help you choose the test combination that fits your health needs and level of risk.

Testing for sexually transmitted infections is highly effective because doctors can use several different types of samples to accurately check for the presence of pathogens:

  • Blood Tests: These are used to check for viral infections like HIV, Hepatitis B/C, and Herpes, as well as bacterial infections like Syphilis. Blood is usually drawn from a vein in the arm (venipuncture) or sometimes obtained via a quick finger prick for rapid screening tests.
  • Urine Tests: This is a common method for screening for infections in the urinary tract, primarily Chlamydia and Gonorrhea. For the most accurate result, you may be asked to hold your urine for two to four hours before providing the sample.
  • Swab Tests: These samples are collected from the specific site of potential infection. This includes:
    • Genital Swabs (urethral/cervical) for Chlamydia, Gonorrhea, or other infections.
    • Oral Swabs to check for pharyngeal (throat) infections following oral sex.
    • Swabs of discharge or sores/ulcers to quickly check for infections like Herpes Simplex Virus (HSV).

Yes. While there is no single, universal test that screens for every conceivable STD with one drop of fluid, doctors can order comprehensive screening panels and multiplex PCR tests that check for a large number of the most common and high-risk infections during a single visit.

By using a combination of blood, urine, and swab samples, a comprehensive panel can quickly and efficiently check for bacterial, viral, and parasitic infections simultaneously. The goal is to maximise the detection of all necessary infections in one session, providing you with a complete picture of your sexual health status.

The time it takes to receive your results varies depending on the specific test being processed:

  • Rapid Tests: Some tests, such as rapid HIV antibody tests done via a blood test (finger prick or arm draw) or oral swab, can provide results very quickly, sometimes in as fast as 20 minutes. These are ideal if you need a quick preliminary answer.
  • Lab-Based Tests: Most comprehensive screenings, which use cultures or Polymerase Chain Reaction (PCR) technology for high accuracy (such as those for Chlamydia, Gonorrhea, or Hepatitis), require laboratory processing. These may involve urine samples or swab tests. Results typically take around 3 to 5 working days.

Your clinic will let you know when and how you’ll receive your results.

Generally, no, STD testing is not painful. The procedures are quick, minimally invasive, and designed to cause as little discomfort as possible.

Most tests involve only one or more of the following:

  • A standard blood draw from the arm, which feels like a slight prick.
  • Providing a simple urine sample.
  • A swab from the throat, genitals, or anus, which is a quick process that may cause a momentary sensation of pressure or mild scraping, but is not painful.

The momentary discomfort is well worth the peace of mind and health benefits that the test results provide.

The physical procedure of collecting the samples for an STD test is generally very fast, typically taking only a few minutes once you are in the examination room.

The consultation with your doctor beforehand, where they discuss your sexual history and determine which tests you need, is usually the longest part of the process, but this is a crucial step to ensure the most accurate and comprehensive testing is performed.

A negative test result means that no infection was detected at the time your sample was collected. This should provide you with peace of mind.

However, it is crucial to discuss the window period with your doctor to ensure that you do not test too soon after a potential exposure. If you tested too early, the doctor may recommend a re-test a few weeks later to confirm the negative result. The doctor will also take this opportunity to provide prevention counseling to help you maintain your sexual health status going forward.

If you test positive for an STD, the immediate next step is for your doctor to discuss and implement an effective treatment plan.

  • For bacterial and parasitic STDs (like Chlamydia, Gonorrhea, and Syphilis), treatment is often a straightforward course of antibiotics that leads to a cure.
  • For viral STDs (like HIV, Herpes, and Hepatitis), your doctor will discuss a plan for managing the condition, which may include medication to suppress symptoms and lower the risk of transmission to others.

This entire process is handled discreetly and professionally, with your privacy as the top priority. Your doctor will also offer important preventive advice and counselling, including how to safely inform and test any recent sexual partners, which is a vital part of stopping the spread of infection.

Yes, your STD test results and the entire consultation are strictly confidential. Healthcare providers operate under medical privacy guidelines, meaning that all your information, including your sexual history and test results, is kept private.

Your test results will only be shared with you. They will not be released to anyone else, including your employer, school, or family members, unless you provide explicit permission or if required by law for public health reporting (where only the diagnosis, not your name, might be reported in some jurisdictions, or where specific infectious diseases are mandatorily reportable, but always handled with strict privacy protocols).

It is helpful to classify STDs into two main groups:

1. Curable STDs
These infections can be completely eliminated from the body with the appropriate course of treatment, typically with antibiotics or antifungal medication.

  • Bacterial Infections: Chlamydia, Gonorrhea, and Syphilis.
  • Parasitic/Yeast Infections: Trichomoniasis and Yeast Infections.

2. Manageable (but not curable) STDs
These are chronic viral infections that cannot be eliminated from the body, but effective medical treatment can control the virus, suppress symptoms, and significantly reduce the risk of transmission to others.

  • Viral Infections: Human Immunodeficiency Virus (HIV), Genital Herpes Simplex Virus (HSV-1 and HSV-2), Human Papillomavirus (HPV), and Hepatitis B and C (although new treatments for Hepatitis C are highly effective and can clear the virus in most people, they are still technically classed differently from bacterial cures).
