A chemical in the test will then fluoresce, which the polymerase chain reaction, or pcr, machine will. However, pcr cannot recognize the entire genetic code of the virus one by one, so pcr cannot also recognize or distinguish virus variants, said the spokesman. Thus, in pooled samples, rt‐pcr graphs should be analyzed for sigmoid curve even beyond the.

It is just a question of semantics, but it means the same as negative, and is a more precise way of giving the result, in medical parlance. A negative result could either mean that the sample did not contain any virus or that there is too little viral genetic material in the sample to be detected. This means that the virus was not found in your sample.

Concern Mounts As Pcr Covid Tests May Not Be Able To Detect New Omicron Variant Version.

The lab gun kit and fosun kit could detect all samples with a good sigmoid graph at high c t value but were interpreted as negative as per manufacturer recommendations. It’s possible that you had the virus, but that: The variant is still detected as coronavirus by all the usual tests, and can be identified as the omicron variant through genomic testing, but probable cases are not flagged up by routine pcr.
