Caffeine is not specifically tested for in most drug tests. Because it is not illegal, there is not much concern about the possibility that companies may specifically test for it.

Athletic Testing: Some athletic associations set limits for caffeine levels in urine. The International Olympic Committee sets limits at 12 µg/mL, which might be reached by consuming about 8 cups of coffee(1). In the United States, the National Collegiate Athletic Association limits caffeine levels to 15 µg/mL(2).

False Positives: Caffeine is not believed to cause false positives for other substances. Contamination of urine specimens has led to a false positive for high caffeine levels in at least one instance(3).
