What is PCR Testing?

Sexual health plays a vital role in your overall well-being. However, many people delay getting tested for sexually transmitted infections (STIs) because of worries about accuracy, privacy, or waiting times.

Thanks to modern science, PCR (Polymerase Chain Reaction) testing has become the gold standard for detecting infections. Unlike rapid tests or blood antibody tests, a PCR test detects the DNA or RNA of the infection itself, not your body’s response to it.

What Does the STI PCR Test Detect?

One of the main benefits of the STI PCR Test is its comprehensive detection panel, covering both common and lesser-known infections — many of which are asymptomatic.

The PCR Panel can test for:

• Chlamydia trachomatis A-K– a common bacterial infection that often shows no symptoms.
• Neisseria gonorrhoeae (Gonorrhea)– a bacterial STI that can cause painful urination and discharge.
• Mycoplasma genitalium (MG)– increasingly recognized as a cause of urethritis and pelvic inflammatory disease.
• Ureaplasma urealyticum (UU)– usually harmless but can sometimes cause urinary or reproductive issues.
• Trichomonas vaginalis (TV)– a parasitic infection that often goes unnoticed but can discomfort, irritation, and increased risk of acquiring other STIs.
• Gradnerall vaginalis (GV)– a bacterial infection commonly linked to bacterial vaginosis (BV). It may cause unusual vaginal discharge and odor, though many people remain asymptomatic.
• Trichomonas pallidum (TP)- the bacteria that cause syphilis, a serious STI leading to genital sores, rashes, and systemic complications if untreated.
• Haemophilus ducreyi (HD)- 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.
• Chlamydia trachomatis L1/L2/L3– strains that cause lymphogranuloma venereum (LGV), leading to swollen lymph nodes and rectal inflammation.
• Candida paraphilosis– a yeast species that may cause genital itching, irritation, and discharge, sometimes resistant to standard treatment.
• Candida tropicalis– another non-albicans yeast causing genital discomfort, redness, and recurrent infections.

(Some panels may also screen for HPV depending on your needs.)

💡 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 Silom Bangkok is fast, discreet, and hassle-free.

1. Step-by-Step Process:

4. Result Analysis: Our specialists review the results, ensuring high accuracy.

When Should You Get an STI PCR Test?

Regular testing is crucial because most STIs don’t show symptoms early on.

Consider a PCR Test If:

• You experience burning during urination, discharge, or genital sores.
• You’ve had a new or unprotected sexual encounter.
• You’re in a non-monogamous relationship.
• Your partner tested positive for an STI.
• You’re scheduling 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.
