False Negative Fecal Occult Blood Test: Prozone Effect
Dear editor, the fecal occult blood test is the presently widely used screening laboratory test for colorectal cancer. At present, the test is usually based on an immunological diagnostic principle (1, 2). A false positive fecal occult blood is common and widely mentioned in literature. Nevertheless, the false negative is little mentioned in the paper. Here, the authors discuss the issue of the...
متن کاملFalse-negative result for cocaine metabolites on a lateral-flow drug test slide corrected by dilution.
To the Editor: Cocaine is one of the most widespread drugs of abuse; therefore, clinical laboratories are frequently requested to screen for the presence of cocaine and its metabolites in urine. When screening a urine specimen from a potential study participant for drugs of abuse, using a Verdict II lateral flow test slide (MEDTOX Diagnostics), multiple technologists obtained a negative screeni...
متن کاملRh ANTIBODIES AND THE PROZONE PHENOMENON BY
In 1942 Taylor, Race, Prior, and Ikin reported an anti-Rh serum which failed to agglutinate Rhpositive cells in saline suspension except when diluted. They thought that this prozone was due to antigen and antibody not being present in optimal proportions, and that the mechanism was similar to that of the zones that occur in precipitation reactions. Wiener (1944) described incomplete Rh antibodi...
