שלום,
רציתי לשאול מה פירוש המושג? בהקשר של HIV?
Examination revealed moderate weight loss, and the laboratory tests of ELISA (Genscreen) and western blot (new blot 1 & 2) confirmed sero-positivity to HIV infection with pre-treatment viral (HIV-RNA) load and CD4 count of 27,000 copies/ml and CD4 count of 250 cells/ mm(3) respectively
Repeated EIA and Western blot tests on 187th day on therapy was sero-negative.

The post therapy CD4 count was 650 cells/ mm(3) with undetectable viral (HIV-RNA) load. Several repeats of the HIV tests remained sero-negative, aviraemia and normal CD4 count since 24 months without therapy.
