I understand that some groups of lab codes contain a methodless code and others don’t.
For component of : HIV 1 RNA
and context quantitiative - viral load
We are mapping clinical trials data (from HIV) to LOINC and we don’t know the method they used.
We would benefit from having a methodless code for this context.
The guidance here is very limited

What is the policy of approving a methodless code?
Are they generally discouraged to even be submitted? (create noise in the LOINC as a terminology)
