CIR/IRMSTestosterone testing - same, different ?

Keith said:

Not sure if CIR is the same as IRMS I wonder if these guys (Landis,
Gatlinà are not taking a chance because the CIR/IRMS testing only gets
done if the T/E ratio looks suspicious to save on costs.

It's the same thing: measurement of the ratio of 13C to 12C (hence,
carbon isotope ratio) of testosterone in urine using a gas
chromatography/combusion/isotope ratio mass spectrometer (GC/C/IRMS).

Thanks for clarifying, since the Landis legal team have started
trashing the IRMS test, I was beginning to wonder.

I wonder if any of these geniuses have found out that you put the
testosterone patch on your arm and not your balls yet?
