[Methods of urine analysis for creatinine after long period of storage].
Our investigations showed that n-cresol (4-methylphenol) stabilized urine and preserves urinal creatinine as long as for 50-d storage at room temperature. This antimicrobial biochemical stabilizer is the core of a novel method of delayed creatinine quantification in urine. It can be useful in metabolic investigations of cosmonauts and nuclear submarine crews, members of alpine, desert, deep-water, Arctic and Antarctic expeditions and in many other cases when samples cannot be analyzed immediately.
