ABSTRACT
In order to determine the effect of the increase in sensitivity of HCMV detection in whole blood compared to plasma on reproductive rate (Ro) measurement, an optimized human cytomegalovirus (HCMV) quantitative PCR assay was developed. The results presented in this study are summarized by the following three methodological improvements (i) at values below the limit of quantitation (LOQ) of 60copies/ml, determination of HCMV load was more sensitive with whole blood than plasma, (ii) for the determination of viral load, whole blood was more sensitive than plasma below 1000copies/ml but little difference was observed above 1000copies/ml and (iii) the measurement of "Reproductive Rate" can be affected by imprecise measurement of HCMV viral load in either plasma or whole blood compartments depending on whether samples were taken from patients on antiviral treatment or from patients where HCMV load was rising. Taken together this study provides methodological improvements suggesting that below HCMV viral load levels of 1000copies/ml (1640IU/ml) both plasma and whole blood should be tested.
