Real-time RT-PCR for Automated Detection of HIV-1 RNA During Blood Donor Screening

Real-time RT-PCR has become the method of choice for automated detection of viral RNA target sequences in the clinical laboratory. Besides commercially available certified test systems, a variety of so-called in-house methods have been described in the literature. Generally, appropriate validation and continuous quality control are mandatory if these in-house-developed assays are used in clinical diagnostics. In this chapter, an in-house HIV-1 real-time RT-PCR assay for blood donor screening is described. The procedure includes the pooling of plasma samples, viral RNA isolation, and subsequent detection of amplification in real-time one-step RT-PCR. The validation considers the specificity, the sensitivity on HIV-1 genomic variants, and the robustness of the assay.
