Frequently Asked Questions
In the reverse testing algorithm for syphilis, you will need to reflex to RPR to find out if you have an active or past infection. For HIV you would need to confirm a positive based on your site’s protocols.
The test components should be at room temperature, 18 to 25 C (64 to 77 F), before performing the test and the test should be performed within the same temperature range. If the temperature of the testing area falls outside of 18 to 25 C (64 to 77 F) it is recommended to perform QC prior to testing.
We do not detect antigen to HIV, just antibodies to HIV, the following papers support this approach to the rapid HIV Testing.
The paper ‘Field Accuracy of fourth Generation Rapid Test’ by Lewis et al analyzed 4 studies that included 17,381 samples screened using 4th generation (Antigen-Antibody) rapid tests.
- 26 reference-standard-defined acute HIV infections were missed
- 35 false positives were observed
Lesson’s Learned: ‘Fourth-generation RDTs are currently unsuitable for the detection of acute HIV-1’ at the point of care.
Why the Poor Test Performance: The assay detects free HIV-1 p24 antigen. This has a short window of detection. “Antibodies form immune complexes with antigen in the bloodstream and preclude binding of antigen to the test strip. This technical difficulty can be overcome with an antigen dissociation step, but this may be hard to implement at the point of care.”
The term “biological false positive” for syphilis is defined as a positive reaction to regain tests (non-trep), but negative reaction to treponemal tests. Non-trep such as RPR, are looking for anti-cardiolipin antibodies which are not specifically associated with treponemal infections, so having a positive RPR and negative Treponemal test is what is usually referred to as a biological false positive when the traditional algorithm is used.
