PCR vs Blood vs Swab: Which STD Test Do You Need in Korea?

Getting tested for STDs in Korea is easier than ever, especially if you visit an English-speaking clinic like Gangnam J Andrology Clinic. But with multiple testing options—PCR, blood, swab—many people wonder: Which test do I need?

Let’s break it down so you can choose the right method with confidence.

What Is a PCR Test?

PCR (Polymerase Chain Reaction) is one of the most advanced and accurate STD testing methods available.

• How it works: Detects the genetic material (DNA/RNA) of bacteria or viruses
• Commonly used for:
• Chlamydia
• Gonorrhea
• Mycoplasma/Ureaplasma
• Trichomoniasis
• Sample type: Urine or swab
• Results: Fast and highly accurate

✅ Best for: People with no symptoms, early detection, or multiple partner exposure

What Is a Blood Test?

Blood tests are typically used to detect viral infections or antibodies produced by the immune system.

• Commonly used for:
• HIV
• Syphilis
• Hepatitis B & C
• Herpes (in some cases)
• Sample type: Blood draw
• Results: Typically available within 3–5 business days

✅ Best for: Long-term exposure, high-risk contacts, and regular health screening

What Is a Swab Test?

Swab tests involve taking a sample directly from affected areas like the throat, genitals, or anus.

• Commonly used for:
• Gonorrhea
• Chlamydia
• Herpes (when lesions are visible)
• Sample type: Swab of affected site
• Results: Fast and accurate for localized infections

✅ Best for: If you have visible symptoms like sores, discharge, or irritation
