Description

For many developing countries resources for monitoring HIV disease are limited. Chen et al developed an algorithm for using the complete blood cell (CBC) count to identify an HIV-positive patient who probably has a CD4 cell count <= 200 per µL. The authors are from the University of Alabama at Birmingham.


 

Parameters:

(1) absolute lymphocyte count per µL

(2) hemoglobin in g/dL

(3) platelet count per µL
