In brief: Probably one.
In the rt-pcr test, viral RNA is extracted from the patient's plasma and treated with reverse transcriptase (rt) to convert the viral RNA into cdna.
The polymerase chain reaction (pcr) process is then applied. This is then quantified. There is a quantiplex bdna or branched dna test, but it is done by centrifuge to concentrate and detect by a color reaction that can be quantified, not pcr.
