Drug test oxycodone and diamorphine may be tested, both sedative analgesics. If such a test is not requested specifically, the more general test (in the preceding case, the test for opiates) will detect the drugs, but the employer or physician will not have the benefit of the identity of the drug. Employment-related test results are relayed to a medical review office (MRO) where a medical physician reviews the results. If the result of the screen is negative, the MRO informs the employer that the employee has no detectable drug in the urine, typically within 24 hours. However, if the test result of
Analgesic nephropathy kidney toxicities of NSAIDs and the antipyretics phenacetin and paracetamol may combine to give rise to analgesic nephropathy. A committee of investigators reported in 2000 that there was insufficient evidence to suggest that non-phenacetin analgesics by themselves are associated with analgesic nephropathy. Proper kidney function depends upon adequate blood flow to the kidney. Kidney blood flow is a complex, tightly regulated process that relies on a number of hormones and other small molecules, such as prostaglandins. Under normal circumstances, prostaglandin E2 (PGE) produced by the kidney is necessary to support adequate blood flow to the kidney. Like all prostaglandins, PGE
