Absolute lymphocyte count from WBC and lymphocyte percent (Shapiro 1998)
Absolute lymphocyte count from WBC and lymphocyte percent (Shapiro 1998). ALC < 1000 cells/mm3 predicts CD4 < 200; ALC >= 2000 predicts CD4 >= 200. Deterministic published arithmetic with citation. Not a CD4 measurement or HIV diagnosis. magent does not measure the CBC.
