Ml. Landry et al., Impact of sample type on rapid detection of influenza virus A by cytospin-enhanced immunofluorescence and membrane enzyme-linked immunosorbent assay, J CLIN MICR, 38(1), 2000, pp. 429-430
Cytospin-enhanced direct fluorescent-antibody assay (DFA) detected 49 (92.5
%) and rapid membrane enzyme-linked immunosorbent assay (ELISA) detected 40
(75.5%) of 53 influenza virus A-positive samples. All 15 positive nasophar
yngeal aspirates from children were detected by both tests. In contrast, 34
of 38 (89.5%) positive swabs from adults were detected by DFA, but only 25
(66%) were detected by ELISA.
