The preemptive therapy of cytomegalovirus (CMV) reactivation is useful for the prevention of CMV disease in allogeneic hematopoietic stem-cell transplant (HSCT) recipients. We compared results of the pp65 CMV antigenemia test with quantitative touch-down polymerase chain reaction (Q-PCR) on unfractionated whole blood for the detection of CMV reactivation in 51 HSCT recipients. Forty episodes of reactivation in 28 patients were detected by antigenemia and treated by antiviral drugs. Q-PCR detected CMV DNA in 39 (97.5%) of 40 reactivation episodes. False-positive results occurred in 3% of tests, of which 63% were borderline positive. Q-PCR results were positive earlier than antigenemia results in 30 (77%) of 39 episodes detected by antigenemia. Q-PCR remained positive after treatment was discontinued in 14 (36%) of 39 episodes and predicted the return of CMV reactivation in 4 (31%) of 13 episodes. Q-PCR was more sensitive than the antigenemia test and had sufficient specificity for clinical use.
