Detected may not be the definite cause of disease. Even though your test right now says the virus was “not detected”, it is possible that you could test positive later.
What they are saying is when they did the test, they were able to find the genetic material of the virus.
What does not detected mean on a covid-19 test. It is possible for this test to give a negative result that is incorrect (false. The results will show as either positive or not detected. Pandemic policy must include defining and measuring what we mean by mild infection.
• a negative antigen test does not definitively rule out infection with the virus. My concern is a result of not detected, does anyone know if. This allows many copies of that material to be made, which can be used to detect whether or not the virus is present.
No action test not performed (tnp) no result consider retest only if clinically indicated. Review symptoms with patient prior to test order. Viral rna is not detected in the sample.
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. No action inconclusive see test result comment. This could be for many different reasons, such as you were tested early in your infection.
Does not mean a positive test. My test result says “not detected”. This means that the virus was not found in your sample.
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. 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.

• cdc recommends confirming negative antigen test results with a pcr test especially if you A negative test means you were probably not infected at the time your sample was collected.
