of a Cryptococcus antigen test owing to Pseudallescheria mycosis.
That mistake can not only strip the buffer system but also generate a false-positive reaction
Antibodies to HCV (anti-HCV) can indicate one of three possible conditions: current active infection with HCV, past infection with HCV, or a false-positive reaction
are not benign; they result in unnecessary chest x-rays, unnecessary fear and concern, and unnecessary treatment in many cases (sometimes with side effects).
The HCV-antibody screen that we offer at our medical center gives us the ability to separate probable false-positive reactions
from true-positive reactions by means of a signal-to-cutoff ratio.
in the latex agglutination test for Cryptococcus neoformans antigen.
This study concluded that joint use of both tests is very useful to identify false-positive reactions
to the screening test is thus expected.
Patch testing can produce highly misleading results, including false-positive reactions
to merthiolate, fragrance, lanolin, or nickel.
Recently, several assay systems have been used to assess endocrine-disrupting effects, but a few of these assay systems can cause false-positive reactions
when test compounds are at high concentrations (11).
burgdorferi whole cell lysates for ELISA can result in false-positive reactions
due to antibody reactivity to flagellin and other common antigens (Magnarelli et al.
Naturally occurring contaminants (bacteria and chemicals such as aluminum chromate and manganese oxide) in site sediments may result in false-positive reactions
in tests (Culliford 1964; Custer et al.
