|PCR RNA testing
Mar 1, 2001
If the new standard in PCR RNA testing is <50 copies, why are some of the reputable labs still using the test using <400 copies. While I realize that this test is not approved for diagnosis,wouldn't more recently infected (say within the last 3-4 months) be missed as their viral load could be <400 or would one's viral load in this scenario be much higher (in the absence of detectable antibodies)?

Viral load levels will be much higher. The lower sensitivity levels are required to measure more effective treatment responses.
