: 48 hours
: HIV is the etiologic agent of acquired immunodeficiency syndrome (AIDS). Quantitative measurements of HIV viremia in the peripheral blood have shown that higher virus levels may be correlated with increased risk of clinical progression of HIV disease, and that reductions in plasma virus levels may be associated with decreased risk of clinical progression. HIV viral load and drug treatment response are closely linked. With successful drug therapy the viral load decreases and with failure the load increases.
: Plasma preparation tube must be centrifuged and refrigerated within six (6) hours of collection. EDTA plasma from a lavender top tube must be separated from the red cells and refrigerated within six (6) hours.
