Insta test after 33 days negative but sore throat and cold present after 37 days could i still have hiv present?

Hi, thanks for writing.

It is normal for people to be worried when they develop flu like symptoms (e.g. fever, rash, sore throat) after they have a sexual encounter they are concerned about. Many people will think the worst. I usually remind people that flu like symptoms are very common and can be caused by many different conditions like a seasonal cold. 

The HIV Insti test you had is considered to be 90% accurate at 30 days. So while that test is not conclusive for you, it is a good sign.

HIV cannot be diagnosed by any combination of symptoms because all these symptoms can be caused by many different conditions. The only way to find out if you have HIV is by having a blood test at 6 weeks, or another Insti test at 3 months.

In the meantime check-out our Worry  & Anxiety page for helpful tips about what to do when you’re worried about an STI.

What generation is the new insti test (point of care) you use in vancouver does it just detect antibodies?

Health Nurse says:

Hi

Yes, the Insti test we use is a 3rd generation HIV antibody test. The standard HIV blood test used in BC Canada is the 4th generation HIV test which looks for antibodies and the p24 antigen in the blood.

Have a look at our calculating HIV window periods page for a tool that shows the different window periods for the 3rd and 4th generation HIV tests.

Let us know if you have anymore questions.
