Bile layering: a cause for false-positive cholescintiscans

Multinucleotide mutations cause false inferences of positive selection

HIV false positive results and Flu vaccination

Abstract False positive results are the major problem influencing interpretation of Clinical Laboratory test. They are originated mostly in the other diseases, technical errors and the recent vaccination. The problem has been presented since 1991 is positive HIV test after influenza Vaccination (1). The False positive has been reported in Cases using Eliza, one of The most common test to screen...

Plasmalyte as a cause of false-positive results for Aspergillus galactomannan in bronchoalveolar lavage fluid.

The detection of galactomannan (GM) in the serum of immunocompromised patients is widely used for the early diagnosis of invasive aspergillosis (6). The test may also be useful when applied to bronchoalveolar lavage (BAL) fluid specimens for clinical diagnosis (5), though not FDA approved for this use. One important limiting factor for GM testing is the potential for false-positive results. Mos...

Bifidobacterial lipoglycan as a new cause for false-positive platelia Aspergillus enzyme-linked immunosorbent assay reactivity.

We previously hypothesized that a lipoglycan of Bifidobacterium bifidum subsp. pennsylvanicum cross-reacts with the Platelia Aspergillus (PA) enzyme-linked immunosorbent assay (ELISA) based on the presence of galactofuranosyl epitopes in the cell wall (M. A. S. H. Mennink-Kersten, R. R. Klont, A. Warris, H. J. M. Op den Camp, and P. E. Verweij, Lancet 363:325-327, 2004). We tested this hypothes...

False-positive and false-negative rates for carcinogenicity screens.

The implementation of a number of chemical carcinogen screening programs has been accompanied by the observation that some screens might have high false-positive error rates. With designs presently used at the National Cancer Institute and historical spontaneous tumor rates based upon control animals in previous experiments, we compute upper bounds on the false-positive error rates for several ...
