- Clinical Testing and Diagnosis for Tuberculosis
It is the only kind of TB skin test solution that is FDA-approved for this test method After 48–72 hours, the skin test reaction must be examined by a trained health care worker The health care worker measures any swelling where the tuberculin was injected to determine if the reaction to the test is positive or negative
- Laboratory Testing for Epstein-Barr Virus (EBV)
Monospot test The Monospot test is not recommended for general use The antibodies detected by Monospot can be caused by conditions other than infectious mononucleosis Moreover, studies have shown that the Monospot produces both false positive and false negative results
- Waived Tests | Laboratory Quality | CDC
Waived tests include test systems cleared by the FDA for home use and those approved for waiver under the CLIA criteria While CLIA requires waived tests to be simple and low-risk, they are not completely error-proof Errors can occur in testing if manufacturer's instructions are not followed or if personnel are unfamiliar with the test system

- Measles Serology Testing | Measles (Rubeola) | CDC
Test turnaround-time for IgG avidity The turnaround–time for testing specimens for IgG avidity is 30 working days after the delivery of the specimens to the measles reference lab by the STATT laboratory Both an acute and a convalescent phase serum are recommended for PRN testing There is no established turnaround–time for measles PRN
- Testing and Diagnosis for Lyme disease | Lyme Disease | CDC
Because the immune system continues to make the antibodies for months or years after an infection is gone, your blood test will remain positive after the bacteria are no longer present Unfortunately, these antibodies don’t reliably prevent re-infection should you be bitten by another infected tick About tickborne co-infections
