Isolation of human immunodeficiency virus (HIV) from whole blood

: The authors describe a simple and sensitive technique for HIV isolation from small amounts of heparinized whole blood. This method demonstrated a high efficiency in detecting HIV at all stages of disease and appeared more sensitive with respect to viral isolation from peripheral blood mononuclear cells. Although further studies are needed to better understand the biological significance of a positive cultural result obtained by this method, HIV isolation from whole blood can be routinely employed, especially when small amounts of blood are available.
