Rapid strep tests are a reliable screening test for most patients to determine whether a strep infection is present. The sensitivity of the rapid test may be as high as 95% depending upon the manufacturer, meaning very few people with a true strep infection will have a negative test result. ...

A rapidHIVtest can test for HIV and return the results in a short period of time, usually 20 minutes. There are two kinds of rapid HIV tests: A rapid self-test can be taken in a private location, while a rapid point-of-care test is given at a clinic or healthcare provider's offic...
The OraQuick Advance Rapid HIV-1/2 Antibody Test (OraSure Technologies, Bethlehem, Pennsylvania) can be done by trained personnel as a point-of-care test for HIV antibody in oral fluid. These characteristics obviate the need for blood drawing and the use of a central laboratory, and the ra...
The cause for the episodic increases in false-positive oral fluid tests has not yet been determined. NYC DOHMH has again suspended the use of oral fluid testing in STD clinics, and finger-stick whole-blood testing is the only rapid HIV test being used in this setting. These findings ...

False positive results can occur with rapid syphilis tests, particularly in individuals with conditions such as lupus, HIV, or other infections that may cause cross-reactivity with the test. False negative results can also occur in early stages of infection, when the level of antibodies may not ...
test in Congo [17] and Gabon [12] with the sensitivities of 57.1% and 90.9%, respectively. The difference between the sensitivities observed could be partly explained by the type of samples tested. Indeed, in the present study, we tested samples from confirmed HIV-positive patients, while in...
rapid detection SARS-CoV-2 antibody tests, e.g., lateral flow immunoassays (LFIAs), seem to have lower accuracy (Guedez-López et al., 2020; Zhang et al., 2020); in particular, the immunochromatographic antibody test is burdened by the high incidence of false positive results of IgG (Sh...
With over 110 million visits to EDs annually, expanded HIV testing may result in a substantial number of false-positive RHT results. We implemented rapid test algorithms (RTAs) in two EDs to distinguish persons likely to have false-positive tests from those likely to be truly infected during a...
