Avidity testing
« on: December 05, 2012, 09:41:29 AM »
Got back some more results today, including a test which is starting to be used for checking how recent an infection is called avidity testing. There's not much info out there that I can see, does anyone have any experience if it? According to this test I acquired the virus less than 6 months before my date of diagnosis.

Other news is good, only low possibility of resistance to one drug, everything else doing a-ok.
Infection sometime April-August, no noticable seroconversion symptoms
Not currently on medication
13/09/12 CD4 672 (33%) VL <40 (diagnosis date)
18/09/12 CD4 ?               VL 43
27/09/12 CD4 ?               VL 127
19/11/12 CD4 676 (38%) VL 959
03/03/13 CD4 642 (32%) VL 291
04/07/13 CD4 791 (33%) VL 26,437 (active cold sore, tooth infection)
18/07/13 ------retest------VL 3704

There's a fairly decent description/definition here.

HIV is certainly character-building. It's made me see all of the shallow things we cling to, like ego and vanity. Of course, I'd rather have a few more T-cells and a little less character. Randy Shilts

The test is in fact a test and an interpretation to make a perhaps 2/3rd accurate guess at whether you acquired HIV in the last 6 months or before that time. The test works by looking for specific antibody markers, which give different results in the months immediately following infection. If a test gives a result below a pre-determined cut-off point, it is deemed to be a recent infection (approximately the last six months). It's an informed guess that's all. Some people find it useful. Some public health monitoring programmes find it useful eg to compare new with longtime cases of HIV.
