Reply To: How long should I wait after exposure before testing?

The reason the numbers differ is that there isn’t one window, there’s a different one per infection and per type of test. Bacterial infections show up on a swab or urine test fairly quickly. Blood-borne ones take longer because you’re waiting on your own body to produce something detectable.

What worked for me was ringing the clinic, telling them the date and what happened, and letting them decide the schedule. They booked me for two visits rather than one.
