Table 2.

Detection of mammalian DNA using Taqman quantitative polymerase chain reaction.

Group Samples, n GAPDH level (Cta), mean (SD)
No virus detected 20 28.4 (2.9)
Virus detected 11 28.7 (2.5)
Low virus detected 5 28.2 (4.7)
Inhibitors present 2 26.1 (3.7)
Not tested for virus 3 23.7 (1.6)

aCt: cycle threshold. A Ct value <40 represents positive detection of human DNA.
