Ref Range Not Detected Covid Test. Labs often set a “cutoff” ct value above which they interpret and can declare a patient “negative” if the virus is not detected after a certain number of cycles. Reference range is the result expected for this test in the absence of disease.
Amplification of both targets results in a presumptive positive (detectable) test result, while amplification of one of two targets results. The nat result is outside the validated range of the test (i.e., rna concentration is below the Inconclusive/presumptive positive or presumed positive means target 1 was not detected but target 2 was detected.

The Results Will Show As Either Positive Or Not Detected.
The icmr has arrived at the ct value of 35 based on laboratory experiences and inputs taken from several virology labs. But that’s not all that unusual. Inconclusive/presumptive positive or presumed positive means target 1 was not detected but target 2 was detected.
Labs Often Set A “Cutoff” Ct Value Above Which They Interpret And Can Declare A Patient “Negative” If The Virus Is Not Detected After A Certain Number Of Cycles.
Inconclusive results (presumptive positive) or presumed positive: Reasons for not testing may include failure to collect the specimen properly, specimen was mislabeled, problems in transport to laboratory, incorrect This allows many copies of that material to be made, which can be used to detect whether or not the virus is present.
• You Are Likely Not Infected, But You Still May Get Sick.
But even though different labs can accurately detect the virus using their pcr. 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. The reference range is used to compare your test result to the normal.
No Action Test Not Performed (Tnp) No Result Consider Retest Only If Clinically Indicated.
The false positive may just mean your body has. Amplification of both targets results in a presumptive positive (detectable) test result, while amplification of one of two targets results. This could be because no sample was.
May Also Indicate That The Result Is Still “Pending” And Includes A Tentative Date When It Will Be Available.
My concern is a result of not detected, does anyone know if. Reference range is the result expected for this test in the absence of disease. • the virus was not detected.
