For a number of reasons, I've long been suspicious of doping charging based on positive nandrolone tests. The latest news adds fuel to the fire. Although letsrun.com's front page points out that "unstable urine" would only result in, at most, one "false positive" per 1,000 tests, the USA Today article states that, "In 2004, WADA's 33 accredited labs worldwide found traces of nandrolone in about 300 of 170,000 tests. In 2003, they found about 250 in 130,000 tests." Assuming one "false positive" per thousand tests, that suggests that more than half of the positive nandrolone tests may have been "false positives." That's a lot of careers and reputations destroyed by inadequate testing protocols.
