Can i calculate my my cd4%?

Sep 9, 2012

If my cd4=592 , cd8=658, cd3=1270 how can i calculate my cd4%? Is the following formula cd4%=(cd4/cd3)*100 correct ? My lab tests never stated my cd4%, and i browsed through this forum and on the internet and this is what i came up with.Am i wrong? Thank you so much.

Response from Dr. Holodniy

You get partial credit. You need to have the total lymphocyte count, usually obtained from the white blood cell (WBC) count and differential. Your calculation gives you results for the percent of t lymphocytes (CD3+ cells, that includes both CD4+ and CD8+ cells, but does not include other lymphocytes like B cells) that are CD4+ cells.
