STI PCR Test: The Most Accurate STD Testing in Bangkok

What is PCR Testing?

Sexual health is a vital part of overall well-being, yet many people put off getting tested for sexually transmitted infections (STIs) because they worry about accuracy, privacy, or waiting too long for results. Fortunately, modern medicine has made huge advances, and one of the most reliable tools available today is the STI PCR Test.

PCR (Polymerase Chain Reaction) testing is different from standard rapid tests or blood tests because it looks directly for the DNA or RNA of infections. While a blood test usually checks for antibodies—your body’s immune response to an infection—this can take weeks to show up. A PCR test, on the other hand, detects the pathogen itself, which means you can find an infection earlier, with greater accuracy.

At SESH Clinic in Silom Bangkok, we specialize in confidential, accurate, and fast STD testing. If you’re considering a sexual health check, here’s why PCR testing may be the smartest option for you.

What Does the STI PCR Test Detect?

One of the strongest benefits of an STI PCR Test is its ability to detect a wide range of infections—many of which are asymptomatic but still harmful if left untreated.

The PCR Panel can test for:

Chlamydia trachomatis– a common bacterial infection that often shows no symptoms.
Neisseria gonorrhoeae (Gonorrhea)– a bacterial STI that can cause painful urination and discharge.
Mycoplasma genitalium– increasingly recognized as a cause of urethritis and pelvic inflammatory disease.
Ureaplasma urealyticum– usually harmless but can sometimes cause urinary or reproductive issues.
Trichomonas vaginalis– a parasitic infection that often goes unnoticed but can cause discomfort and irritation.
Gradnerall vaginalis– a bacterial infection commonly linked to bacterial vaginosis (BV). It may cause unusual vaginal discharge and odor, though many people remain asymptomatic.
Trichomonas vaginalis– a parasitic infection that often goes unnoticed but can cause discomfort, irritation, and increased risk of acquiring other STIs.
Haemophilus ducreyi- the bacteria responsible for chancroid, a rare but serious STI that causes painful genital ulcers and swollen lymph nodes.
Group B Streptococcus (GBS)- a type of bacteria that may live harmlessly in the body but can sometimes cause urinary or reproductive tract infections, particularly in women.
Candida albicans- a yeast infection that may lead to itching, burning, and abnormal discharge in the genital area.
Candida glabrata- another yeast species that is less common but often more resistant to treatment, causing similar symptoms of genital yeast infections.
Herpes simplex virus type 1 (HSV 1)– a viral infection often associated with cold sores but can also cause genital herpes through oral-genital contact.
Herpes simplex virus type 2 (HSV 2)– the more common cause of recurrent genital herpes, leading to painful sores, blisters, and increased HIV transmission risk if left untreated.

Depending on your needs, some PCR panels may also screen for Human Papillomavirus (HPV).

Why this matters: Many STIs are “silent.” For example, up to 70% of women and 50% of men with chlamydia don’t show obvious symptoms, yet the infection can cause infertility if untreated. PCR testing gives you peace of mind by catching these infections early.

How Does the PCR Test Work?

Getting tested at SESH Clinic is simple, discreet, and fast. Here’s what happens:

Sample Collection– Depending on the suspected infection, we collect a swab from the genital area, throat, or rectum. Alternatively, a urine sample may be enough.
DNA/RNA Amplification– In the laboratory, the test uses advanced molecular techniques to amplify the genetic material of the infection.\
Result Analysis– Our specialists review the results carefully. Because PCR looks directly for the pathogen, it delivers higher accuracy than rapid or antibody tests.

The process usually takes only a few minutes at the clinic, and most patients receive same-day results, allowing for immediate treatment if needed.

Key Benefits of the STI PCR Test

The STI PCR Test is widely regarded as the gold standard, and here’s why:

High Accuracy: Detects infections that might be missed by traditional tests.
Early Detection: Identifies STIs before symptoms appear, preventing complications.
Comprehensive Panel: Screens for multiple pathogens in one go.
Fast Results: Get answers within the same day at SESH.
Discreet Testing: No need to wait weeks or worry about false negatives.

At SESH Clinic, we we combine medical expertise with a confidential, judgment-free environment, so you can feel comfortable while protecting your health.

When Should You Get an STI PCR Test?

Many people wonder whether they should get tested only when symptoms appear. The reality is: STIs don’t always cause symptoms. That’s why regular testing is part of responsible sexual health care.

You should consider a PCR test if:

You have symptoms like burning urination, unusual discharge, genital sores, or pelvic pain.
You’ve had a new sexual partner or an unprotected encounter.
You’re in a non-monogamous relationship and want peace of mind.
A partner tested positive for an STI.
You’re getting a routine sexual health check.

Pro tip: Even if you feel healthy, getting tested every 6-12 months (or more frequently with multiple partners) is highly recommended.

You may be asked to avoid urination for at least one hour before giving a urine sample. Otherwise, no special preparation is needed.
