Hi, I am involved in legal proceedings whereby parties shave been requested to undertake urine drug testing pursuant to chain of custody requirements. One of the parties returned results where creatinine levels were 0.95 mmol/L. There was a notation on the results that reads very low level of creatinine measured . Is it correct to assume that there is a possibility that the urine sample was diluted and adulterated? Would this justify a request to request a recollection of specimen? Your assistance is greatly appreciated.
