M. Zazzi et al., LOW HUMAN-IMMUNODEFICIENCY-VIRUS TYPE-1 (HIV-1) DNA BURDEN AS A MAJORCAUSE FOR FAILURE TO DETECT HIV-1 DNA IN CLINICAL SPECIMENS BY PCR, Journal of clinical microbiology, 33(1), 1995, pp. 205-208
To determine the sensitivity of a nested PCR procedure for detecting h
uman immunodeficiency virus type 1 DNA in clinical specimens, 553 peri
pheral blood mononuclear cell samples obtained from 268 human immunode
ficiency virus type 1-seropositive subjects were assayed by use of two
independent primer sets for each sample. Overall, 1,088 of 1,106 (98.
37%) reactions were positive. Investigation of the negative reactions
showed that a low viral burden in some infected subjects, rather than
primer-template mismatches, was the primary cause for the false-negati
ve PCR results.
