Inconclusive/presumptive positive or presumed positive means target 1 was not detected but target 2 was detected.

Reference range not detected covid positive. Your covid 19 sample remains positive. Your lab results may also include one of these terms: “the high [positive predictive value] seen in this study reinforces the rationale for pcr testing to identify new cases,” they added.

This test does not give information about past infections or future immunity. Positive or abnormal, which means the disease or substance was found Please be advised that it is unclear, at this time, how long the virus remains detectable in samples.
