Sounds like MLB testing in this area has advanced. You may recall this was the test Braun failed but beat the wrap on a technicality.
Like almost every other testing program, Baseball’s program uses a testosterone to epitestosterone (T/E) ratio of 4:1 as a screening device. Unlike most other programs, however, the fact that a sample has a T/E ratio below 4:1 does not mean that sample is free from further analysis. · The characteristics of every sample, including the T/E ratio, are analyzed at the WADA-certified laboratory in Montreal and the laboratory determines which samples are subjected to Carbon Isotope Ratio (CIR) testing. · All samples with a T/E ratio above 4:1 are subjected to CIR but so are many samples with a T/E ratio less than 4:1. Christiane Ayotte, the Director of the WADA-certified laboratory in Montreal, stated: “The procedures used in the Montreal Laboratory make more extensive use of CIR than those used in other labs and there is no doubt that Baseball’s program detects testosterone positives that other programs would fail to detect.”
A key point that has been overlooked in much of the reporting is that the T/E ratios below 4:1 can be further tested.

One point - the director states that MLB's program detects positives that other programs wouldn't - is there a chance (and if so, how significant) that some, most, or all of those additional positives are false positives?

They do take two samples. Players have an appeal process so it sounds like they have it covered. Braun was a testosterone guy.
