In medicine, the lymphocyte count is "the number of lymphocytes per unit volume of blood."[1] It may further be divided by lymphocyte type, such as B-cell or T-cell, and then T-CD4+ or T-CD8+.
Clinical uses
Measure of nutritional status
A total lymphocyte count less than 2100 is a marker (although a weak marker) of poor nutrition.[2]
Measure of immune status
In predicting a CD4+ T-cell of less than 200:[3]
- Total lymphocyte count of more than 2000 has sensitivity or 95%
- Total lymphocyte count of less than 1200 has specificity of 95%
