Absolute Lymphocyte Count Thresholds: A Simple, Readily Available Tool to Predict the Risk of Cytomegalovirus Infection After Transplantation.

This study of 64 solid organ and hematopoietic stem cell transplant recipients found that peripheral blood absolute lymphocyte count of <610 and <830/µL, respectively, correlated with cytomegalovirus infection. In an era when sophisticated measures of CMV-specific T cells are emerging, we emphasize the utility of the inexpensive and readily-available absolute lymphocyte count.
