The accuracy of saliva anti-HIV antibody testing has been demonstrated in numerous studies; two recent large-scale studies found both sensitivity and specificity to be 100%. The first of these was published in 2008 by Zelin, et al., and compared saliva antibody testing and serum antibody testing using ELISA technique in 820 individuals. [ 53 ]
The test is simpler and cheaper but less accurate than nucleic acid tests. It can be deployed in laboratories or at point of care and gives results in 15 minutes. [163] A false negative result occurs if the sample's antigen level is positive but below the test's detection limit, requiring confirmation with a nucleic acid test. [164]
Ellume reports that its home test results are 96% accurate. ... Vault Health: Travelers 5 and older can take this saliva test at home with real-time supervision via video chat.
Most rapid tests are processed using a nasal swab, but a few use saliva instead. The P23 Lab test from MyLabBox, for example, is a PCR test that analyzes saliva samples, but it’s not exactly ...

A drug test (also often toxicology screen or tox screen) is a technical analysis of a biological specimen, for example urine, hair, blood, breath, sweat, or oral fluid/saliva—to determine the presence or absence of specified parent drugs or their metabolites.
Those behind the University of Edinburgh pilot project said it is potentially more accurate, less invasive and cheaper than current methods. Scientists develop ‘transformative’ saliva Covid ...
A range of test have been developed including smartphone based platforms, and tests targeting blood, saliva, faecal matter, urine, and tears have been proposed. [16] Saliva in particular may offer sufficiently high detection rates in tandem with a non-invasive and user friendly procedure, although reliability requires improvement. [17]
