In a TB study, Quantiferon Gold plus TB test is being used for assessment. I’d like to know which LBTESTCD to be used for the same. While doing some research on the web, I came across a CT Request sheet where CDISC has recommended the sponsor to use ‘MYTBGIR’ (M. tuberculosis IFN Gamma Response), whereas in TAUG-TB ver 2.0, in an example for the specific test, LBTESTCD is given as INFG.
In my opinion, IFNG is more generic when compared to MYTBGIR. Any thoughts/inputs appreciated.
