Subpart I—Problems in Drug Tests

§ 40.199 What problems always cause a drug test to be cancelled?
 
(a) As the MRO, when the laboratory discovers a “fatal flaw” during its processing of incoming specimens (see §40.83), the laboratory will report to you that the specimen has been “Rejected for Testing” (with the reason stated). You must always cancel such a test.
 
(b) The following are “fatal flaws”:
 
(1) There is no printed collector's name and no collector's signature;
 
(2) The specimen ID numbers on the specimen bottle and the CCF do not match;
 
(3) The specimen bottle seal is broken or shows evidence of tampering (and a split specimen cannot be redesignated, see §40.83(g)); and
 
(4) Because of leakage or other causes, there is an insufficient amount of urine in the primary specimen bottle for analysis and the specimens cannot be redesignated (see §40.83(g)).
 
(c) You must report the result as provided in §40.161 .
