Ordering Guidance

If employees are being monitored in the workplace, OSHA requires that laboratory reports express the cadmium excretion rate per gram of creatinine rather than per 24 hours. Order CDUOE / Cadmium, Occupational Exposure, Random, Urine to accommodate that requirement. Mayo Clinic Laboratories is certified to provide this test.
