Hi all, There are two similar tests which require LOINC mapping
They are RT-PCR for Influenzae A, H7 subtype’ and 'Influenza A virus H7 subtype PCR – screening
The different is that the ‘screening’ test may perform a PCR test for influenza A first to exlucde all flu A negative cases and will only perform H7 for flu A postive cases.
Both tests have same analyte, answer (pos/neg for H7) and method (probe.amp.tar); however, the procedure/target gene within is quite differnt. Should these kind of tests be splitted into two differnt LOINC mapping?
