Tampering with the sample

A patient is found, via a discreetly witnessed observation, to have secretly added a foreign substance to a urine sample to produce an abnormal laboratory result, on more than one admission. There is no pending compensation claim, disability application, or legal proceeding of any kind, and no other apparent benefit from the abnormal result. The patient appears distressed when this is discovered and minimises the behaviour, but does not offer any external reason for it.
