Blood Collection Time

Feb 22, 2004

I have had 2 blood tests in the last 12 months where the blood draw was at 9:00 AM and arrived to the lab 8 hours later. Both times my CD4 absolute and percent have been considerably lower than other times when the blood arrived to the lab a lot earlier than 8 hours. Can the way the blood is handled and the length of time it takes to arrive at the lab effect the results? In my case it was a difference of about 80 absolute and 6 percent both times. Other times it was very stable. Thank You

Response from Dr. Holodniy

It is unlikely that this time delay alone would have resulted in such dramatic changes.

Undetectable to 89
