When it comes to STDs and specifically, STD testing windows, you want an STD to show up in the petri dish as if it were the biggest fish in that small pond – VERY obvious – lest you receive a false negative, right? Ok, maybe not – I was reaching for straws with this picture today…..it’s not always easy to find some cool picture that’s applicable to STDs aside from horrible extreme cases of blisters or the like; so, bear with me on occasion when I fish *I’m hilarious* for relevant images! 
Nevertheless, the point remains the same, if you have an STD, you want to know with certainty so you can treat it or start managing it; and if you don’t have one, you also want to know that without question!
So, here’s your go-to guide for the most commonly tested STDs – the ones the clinics often test for free or very low cost and the ones you can even order tests for right in the comfort of your own home…
After someone is exposed to a disease and becomes infected, there is generally a period of time before a test will show positive. That period is known as the window period, and it is different from the incubation period, which, is the time that passes between being exposed to a disease and starting to experience symptoms. STD testing windows vary by STD, so it’s important to make sure you’ve matched the window period with the specific STD(s) you are getting tested for.
How long it takes to test positive for an STD can depend on a number of factors including:
- Whether the test is looking for the pathogen that causes the disease, or your immune system’s response to the pathogen
- The specific test that is being done. For example, aDNA amplification test that looks directly for the organism would usually be able to detect an infection more quickly than an antibody test that needs to wait for an immune response
- The health of your immune system and whether you have been exposed to a similar infection before
With that in mind, typical STD testing windows are:
- Chlamydia Urine Test:
- Possible Detection – Within the first week
- Most Likely Detection – 2 Weeks
- Highest Accuracy – 4 Weeks
- Gonorrhea Urine Test:
- Possible Detection – Within the first week
- Most Likely Detection – 1-2 Weeks
- Highest Accuracy – 2-3 Weeks
- Herpes Simplex 1 & 2 Blood Test:
- Possible Detection – 3 Weeks
- Most Likely Detection – 4-6 Weeks
- Highest Accuracy – 6-12 Weeks
- Syphilis Blood Test:
- Possible Detection – 1-2 Weeks
- Most Likely Detection – 6 Weeks
- Highest Accuracy – 12 Weeks
- HIV Antibody Test *:
- Possible Detection – 3 Weeks
- Most Likely Detection – 4-6 Weeks
- Highest Accuracy – 12 Weeks
- HIV Early Detection Test **:
- Possible Detection – 1-2 Weeks
- Most Likely Detection – 3 Weeks
- Highest Accuracy – 3-4 Weeks
- Hepatitis A Blood Test:
- Possible Detection – 2-3 Weeks
- Most Likely Detection – 3-6 Weeks
- Highest Accuracy – 6-7 Weeks
- Hepatitis B Blood Test:
- Possible Detection – 1-6 Weeks
- Most Likely Detection – 6-10 Weeks
- Highest Accuracy – 12 Weeks
- Hepatitis C Blood Test:
- Possible Detection – 4-5 Weeks
- Most Likely Detection – 6-9 Weeks
- Highest Accuracy – 10-12 Weeks
Lastly, it’s essential to remember, during incubation or window periods, an infected person can transmit the infection/disease to someone else.
So, get re-tested after 6 months of receiving a negative result to ensure a false-negative did not occur if your partner tested positive for an STD, you believe you received a false-negative, you are experiencing symptoms, or you were newly exposed.
*According to the CDC, most people infected with HIV will develop detectable antibodies within 25 days of exposure and 97% of people will have HIV antibodies by three months after exposure.
**STD testing experts recommend confirming this with the ELISA HIV test , which is considered the gold standard in HIV testing, at 3 months post-exposure.
