Following is a response from Senior DHS Specialist, Joy Fishel:
You are treating the inconclusive code "9" as missing and excluding it from the denominator. The HIV prevalence should include inconclusive cases in the denominator.
This denominator represents every case that completed the HIV testing algorithm with a final result. Indeterminate and inconclusive, according to the lab folks, are valid final results that are not HIV positive, and they should be treated the same as a negative result for the purpose of prevalence calculation.
