About this test

An HIV PCR test — a nucleic acid test — looks for the virus's genetic material in a sample of blood drawn from the arm, rather than for your immune system's response to it. Because it looks for a different thing, it can give an answer earlier after a possible exposure than an antibody test can. It is the more expensive option and it does not remove the need for follow-up: a negative PCR early on narrows the picture rather than closing it. The sample goes to a laboratory, and a doctor goes through the report with you rather than handing you a printout.

Who should get this test

  • Anyone whose doctor has recommended it after discussing a specific exposure
  • Anyone who needs a clearer answer sooner than an antibody test can give one
  • Anyone following up a result that needs clarifying
  • Anyone testing as part of a plan already agreed with a clinician

Window period timeline

  1. Day 0 – 10

    Too early even for PCR. There is usually not yet enough virus in the blood to detect. Within 72 hours of an exposure, PEP is the time-critical conversation; the testing plan comes after it.

  2. Day 10 – 33

    Where PCR earns its cost. This is the period in which it can detect the virus's genetic material while an antibody test would still be blank. A positive is acted on immediately; a negative narrows the picture but is not yet an all-clear on its own.

  3. Day 33 – 45

    Past PCR's best use. By this point a fourth-generation antigen/antibody lab test is generally the better instrument, and it is typically conclusive by day 45. The doctor will usually move you onto that rather than repeat the PCR.

  4. Day 45 – 90+

    Confirmation. A negative fourth-generation lab test at 45 days is conclusive for that exposure; a rapid antibody test reaches the same point at 90. Which of these applies to you depends on what you were tested with, and the doctor will tell you plainly.

When to get tested

  • From about 10 days after a possible exposure — earlier than that, there is usually not enough virus present to find.
  • Between roughly 10 and 33 days is the window in which a PCR is most useful; past that, an antigen/antibody lab test is generally the better instrument.
  • A negative PCR is not a final all-clear on its own. Plan on a follow-up antibody test at the interval the doctor sets.
  • If the exposure was within the last 72 hours, ask about PEP before you plan any testing at all.

Preparation

  • This is a draw from a vein in the arm, so wear something with a sleeve that rolls up easily.
  • No fasting is needed for this test, and you can eat and drink as normal.
  • The result is not same-day — check the turnaround above before planning around it. You collect it by logging in; we will not send it by email, SMS or LINE.

Dr. Anucha Wattanakul

Medical Director · HIV & Sexual Health

Anucha has spent most of his career in HIV medicine, first in the public hospital system and then in community clinics across Bangkok, where he ran a PrEP programme for six years. He set this clinic up around a single observation from that work: people do not avoid testing because they do not understand the medicine, they avoid it because of the waiting room. He sees PrEP and PEP patients and leads the clinic's clinical governance.

From our patients

What patients say

I had put this off for nearly two years, mostly because of the idea of sitting in a waiting room where everyone could guess why I was there. It is a normal reception with normal people in it. Booking took a minute, nobody asked for ID, and the doctor read the result with me himself instead of handing me an envelope. Half an hour, start to finish.
K. T. · Rapid HIV test
I came in with a question I had been too embarrassed to ask anywhere else, and left with an answer and no lecture attached. What I noticed most was that the doctor told me which test I did not need. I had expected to be sold the expensive one.
ป. ส. · Sexual health consultation
I called on a Sunday about PEP and was told to come straight in rather than wait for a slot. The clock mattered and they treated it that way. Everything since — the follow-up testing, the switch onto PrEP afterwards — has been handled by the same two people, so I have never had to explain the story twice.
M. R. · PEP, then PrEP
My biggest worry was whether Japanese would be understood; the test itself was almost secondary. From the phone call to paying at the end, all of it was in Japanese.
Y. N. · Full STI screening
I asked what would happen to my records if my insurer ever came asking, and the answer was specific rather than reassuring — which is what I wanted. They told me what goes on the receipt and what does not, before I had paid for anything. The test took less time than the conversation did.
J. B. · Syphilis test
I booked at ten at night on my phone and got a slot the next morning. I did not have to speak to anybody until I was standing at the counter.
อ. ว. · Routine check-up
This was my third visit for PrEP follow-up. It is the same doctor every time, and she remembers the last conversation, so I do not have to start it again.
S. K. · PrEP follow-up
The result arrived as a message saying only that something was ready, with a link, and the link asked me to sign in. So I read it on my own laptop at home rather than on a phone screen on the BTS. Whoever decided that had thought about where people actually open these.
R. L. · Results
The price I saw when I booked was the price I paid. Nothing appeared at the end that had not been there at the start.
น. จ. · Chlamydia and gonorrhoea test
I turned up without an appointment and expected to be turned away. There was a wait, but I was seen the same day, and somebody told me why the wait was happening before I had to ask. There is nothing showy about the place, and that is the point.
T. H. · Walk-in visit
I had already decided the worst had happened before I walked in. The doctor did not rush that, and did not pretend a test could tell me something it could not tell me yet.
D. M. · Consultation
The hard part was never the test. It was telling my partner. I asked the doctor how to say it, and she actually answered instead of pointing me at a leaflet.
