QASI
A program for evaluation of laboratory performance in developing countries

QASI, an international program for quality assessment and standardization for immunological measures relevant to HIV/AIDS, is a performance assessment program for T lymphocyte subset enumeration. QASI's goal is to meet the performance assessment needs of immunophenotyping laboratories in countries where such supportive infrastructures are unavailable.HIV vaccine trials are or will be conducted in countries where incidence and prevalence of HIV infection is high. Quality assessment is the first step towards proficiency testing programs of nations or regions where it is critical to assure the reliability of CD4 T-cell measurements.
