Definitions for "BDNA"
(branched DNA) assay: laboratory test for measuring the amount of virus in blood plasma. The test detects an amplified luminescent signal whose brightness depends on the amount of viral RNA present.
abbreviation, See branched DNA assay.
A test developed by the Chiron Corp. for measuring the amount of HIV (as well as other viruses) in blood plasma. The test uses a signal amplification technique, which creates a luminescent signal whose brightness depends on the viral RNA present. Test results are calibrated in numbers of virus particle equivalents per milliliter of plasma. bDNA is similar in results but not in technique to the PCR test (see).
