group M subtypes and HIV-1 group O is selected for
amplification and detection.

Limit of detection : 20 copies/ml

Specimen : EDTA PLASMA

HIV -1 RNA Detection(Qualitatitve)- NOT DETECTABLE

Result Interpretation:
• A "positive" HIV-1 RNA result indicates a HIV-1 infection in the individual.
• A "NOT DETECTABLE" result indicates the absence of HIV-1 infection or the individual with viral less than 20 copies.



Questions:

1.What does it indicates positive or negative?
2.Generally i see a word 'Not detected' for negative result,but my result is 'Not  detectable' this both words means the same thing?

Thank you.

Yes as you said result will be undetectable for people who take hiv medications.

If possible pls answer my specific questions,I will be grateful to you.

1.I see many labs are mentioning the word 'not detected' but my report says 'not detectable'really there is any difference between this two words?

2.if I take a person who not exposed to hiv for this test to the laboratory where I performed,result will be 'not detectable'?

Thanks
