MLB says lower ratios may trigger more drug tests

NEW YORK (AP) - Baseball and its players' union say urine samples in drug tests may be subject to additional analysis even if the ratio of testosterone to epitestosterone is under the level that typically is considered a positive.

The joint statement Monday came five days after San Francisco outfielder Melky Cabrera, the All-Star game MVP, was suspended for 50 days for testosterone.

Most drug-testing programs consider a T/E ratio of 4-to-1 or higher to be a positive, but in baseball, samples are potentially subject to further scrutiny if the ratio is below 4-to-1. The usual ratio in adults is 1-to-1.
