absolute lymphocytes
Oct 10, 2006

My absolute lymphocyte value is 4243. What does this mean? Thanks.

Response from Dr. Young

Thanks for your post.

Lymphocytes are one type of white blood cell. CD4s represent a large part of the lymphocyte population.

The absolute lymphocyte count (ALC) is a measure of how many lymphocytes there are in the blood; in countries where CD4 counts are not available, the ALC is sometimes used as a substitute marker for CD4s. While not the most accurate, an ALC less than 1200 roughly corresponds to a CD4 of less than 200 cells; an ALC of 1700 is about the same as a CD4 count of 350.

So, in your case, an ALC of 4200 means that you likely have a normal CD4 count.

I hope this helps. BY
