Does low CD4 count show any abnormal results in CBC with differential?
H, Because most blood test reference ranges (often referred to as ‘normal’ ranges of blood test results) are typically defined as the range of values of the median 95% of the healthy population, it is unlikely that a given blood sample, even from a healthy patient, will show “normal” values for every blood test taken, in this case the CD4 result. Therefore, caution should be exercised to prevent overreaction to mild abnormalities without the interpretation of those tests by your examining physician. Again, a blood test, though important, is only a part of the final diagnosis of a health problem. CD4 is a symbol for glycoprotein expressed on the surface of some lymphocytes, including Helper T-cells. Human CD4 is the receptor that serves as a docking site for HIV viruses on certain lymphocyte cells. Binding of the viral glycoprotein gp120 to CD4 is the first step in viral entry, leading to the fusion of viral and cell membrane. White blood cells are composed primarily of neutrophils, mon
