Can Quick Tests be inaccurate?
« on: June 24, 2020, 06:21:14 am »
I always wondered about this. About 5 years ago I had a Quick Test where my finger was pricked, and it showed I was negative, this is when I was living over in Thailand, and I felt great relief at the time.

Of course a couple of years later I started to get sick with various OI's and ended up getting my DX and finding out that I am positive.

I've always wondered if the quick test I did approx 5 years ago was a false negative?

I'm assuming, since I ended up with an advanced Dx that I was positive for up to 10 years before Dx, so my ID Doc says. I explained about this quick test, and he said it was probably a false negative and didn't rate the accuracy of a Quick Test in Thailand

It something I often think aback on, and always wondered what the odds of a false negative are?

Based on test/lab results, outside of picking up on a recent infection, there is no way to know how long you have been living with HIV. Some people progress very fast within a brief few years to AIDS others takes decades.

As for the test, depends on what test. If it's was an approved and recognised test, not one of these fakes or dogy ones on the market and taken correctly and after the window period, the odds of a false negative are minute to non-existent.

I do understand the wondering or questioning past results etc, I've done that myself for a few years, it got so back it used to even keep me up at night and I had a reoccurring dream at some stage, that was until I concluded or accepted, it's best to let it go and stick to the facts I have.

Iíve been wondering the same thing recently. How accurate are these quick tests?
About 5 months before my diagnosis, I took an Oraquick Test.. purely out of curiosity and because I hadnít been tested in a while. The result was negative. 5 months later I had a CD4 count of 55 and VL of nearly 1 million.

Immediately after the diagnosis, i carefully read the directions again and and did two more oraquick tests (I was in the deep denial stage) they both came in negative. I read somewhere that in advanced infections, there are much less antibodies so Iím assuming the tests had a hard time registering an infection.  Does that sound about right? Anyone else have a similar experience?

Hiya,

The tests generally would pick up on antibodies at advanced infection, AIDS stage. They are highly accurate for screening but as with everything not perfect.
