If your test result shows a value of “positive” or “detected,” that falls outside of the reference range and would be. My concern is a result of not detected, does anyone know if.

Even though your test right now says the virus was “not detected”, it is possible that you could test positive later.

What does reference not detected mean on a covid test. It is flagged as abnormal. Viral rna is not detected in the sample. A patient can have a low ct value, which means her viral load is high enough to be detected rapidly, but she may still be asymptomatic.

If you get this type of result you are advised to get tested again for a clear result. The results will show as either positive or not detected. What youve sent indicated that this is a positive covid test result.

This is only to tell you what the test should be. This is a + covid test. The arrival test reference number is the number you are given when you book and pay for your day 2 and 8 covid tests (or only day 2 if a green country or after 19.07.21 for the fully vaccinated at least 2 weeks before, your day 2 test) you need it for your passenger locator form.

The lab didn’t find whatever you were tested for. A negative test means you were probably not infected at the time your sample was collected. A positive nat does not necessarily mean that a patient is infectious, as viral rna can be shed in the respiratory tract for weeks but cultivatable (live) virus is typically not detected beyond 8 to 10 days after symptom onset.

Surveillance testing is primarily used to gain information at a population level, rather than an individual level, and generally involves testing. So if you had a test for strep throat, testing positive means you do have strep throat. Your immune system cleared it by the time you were tested

It’s possible that you had the virus, but that: ‘not detected’ doesn’t mean it’s not there. However, a negative test result does not.

A reference range is the value that the lab considers normal or typical for a healthy person. This means that the virus was not found in your sample. This could be for many different reasons, such as you were tested early in your infection.

Inconclusive/presumptive positive or presumed positive means target 1 was not detected but target 2 was detected. Many coronavirus test results already say “detected” or “not detected” as their default readout, a distinction that several experts call. “what they mean when they say 'detected' is positive.

He says it’s because there are two types of tests, but the answer he says is simple. Inconclusive results (presumptive positive) or presumed positive: My test result says “not detected”.

A negative result for strep throat means that. Detected and positive are the same thing. The reference range would be a negative result.
