Understanding Viral Load Assays for Cytomegalovirus and Epstein-Barr Virus

Viral Load Assays, cont.

March 2010

As you can see, there are a lot of points of variability. In the following slides, I will discuss how these variables can affect the results of viral load assays, and what the potential implications are for patient care.
