biological passport
 n.Gloss: a continuous record of a professional bicyclist’s drug tests. «In an effort to rescue the sport’s prestige, the International Cycling Union plans to institute what is known as a “biological passport.” Cyclists will be subject to monthly blood testing. Failure to present their testing “passport” would disqualify them from competitions like the Tour de France.» —“Straight dope on drug testing” by Cathal Kelly Toronto Star (Canada) Dec. 15, 2007.
