I have read some of the info on this and wanted clarification.

-If I were to be infected at the same time with HIV and HCV would that delay my HIV antibody testing window?

-Most of the info I have read states that if you have HCV and then get HIV the window period is 12 weeks.

- I have also read that if you get both at the same time although rare you would have to test out to 6 months for HIV.

- I have tested negative HIV in the USA with an at home rapid test during weeks 6,8,9,12,13,13.5

Hoping you can ease my fears!

Thank you for contacting the AIDS Vancouver Helpline as your source for HIV/AIDS related information. I will try my best to help ease your fears by providing you with some links and facts.

First, having a diagnosis of Hepatitis C does increase your chances for getting HIV. However, simply having Hepatitis C does not affect the window period for HIV testing. You must be on treatment for Hepatitis C to experience any effect to your testing times. There are only 4 things that affect the HIV testing window period:

1. If you are currently receiving antiviral treatment for Hep C
2. If you are currently receiving treatment for cancer
3. If you have an underlying immunodeficiency
4. If you have received Post Exposure Prophylaxis (PEP) medication after exposure

If you do not have any of these things specifically, then your [HIV testing]( period is at 3 months or 12 weeks after the last high risk exposure. If you have the first 3 of these factors, then your testing window period is 6 months. If you have the last factor and have received PEP, then your window period is 3 months after the last dose of PEP. From what you have described, you do not have any of these factors and your window period should be at 3 months.

With regards to the HIV tests that you have taken, I would like to say that it is wonderful that you have been tested. While this is the case, home HIV tests are not always the best option. For example, AIDS Vancouver does not endorse the use of the home oral test as their is a high chance for human error and therefore, inaccurate results. In addition, home HIV tests are not approved in Canada. HIV testing through a laboratory or with a medical professional is recommended. Since your last home test was done at 13.5 weeks after your exposure, you are at the conclusive time period and testing a test site would give you conclusive results at this time. To help locate a site near you, you may use the [CDC test site locator](
