Abstract:
OBJECTIVETo establish a national reference panel for HIV RNA diagnostic reagents.
METHODSSera from patients with HIV infection and healthy blood donors were collected and tested for HIV and HCV antibodies and HBsAg by using ELISA. The HIV antibody positive samples with ELISA were confirmed with HIV Blot 2.2 (Genelabs). The quantitative samples for HIV RNA were calibrated with the WHO HIV RNA standard. The stability of the panel was evaluated with acceleration method.
RESULTSAfter screening and calibration, 8 negative samples, 8 positive samples, 3 quantitative samples, 6 sensitivity samples and 5 samples for linear analysis were composed of the national reference panel for HIV RNA. The convinced international units (IU) for the quantitative samples were obtained by seven independent calibration and the logarithm of international units for the quantitative samples (b1-b3) were less than x +/- s. The results showed that this panel may stabilize for 4 days at 4 degrees C.
CONCLUSIONA national reference panel for HIV RNA reagents has been established. It may provide the basis for evaluating HIV RNA diagnostic reagents.
