Adulteration of Urine by “Urine Luck” [PDF]

open access: yesClinical Chemistry, 1999
Abstract Background: In vitro adulterants are used to invalidate assays for urine drugs of abuse. The present study examined the effect of pyridinium chlorochromate (PCC) found in the product “Urine Luck”. Methods: PCC was prepared and added to positive urine controls at concentrations of 0, 10, 50, and 100 g/L.

Methotrexate in the urine [PDF]

open access: yesKidney International, 2011
A 62-year-old man with a recent diagnosis of primary central nervous system lymphoma developed acute kidney injury (AKI) after administration of high-dose methotrexate. AKI developed within 48 h of therapy despite prior infusion of intravenous bicarbonate solution. Serum methotrexate level was 2.61 μmol/l at 24 h and 0.25 μmol/l 72 h after methotrexate

Green Urine [PDF]

open access: yesThe Scientific World JOURNAL, 2011
Urinalysis is an integral part of a thorough patient evaluation. Change in urine characteristics can give clues to help solve some of the diagnostic challenges faced by physicians. We discuss a case of a benign cause of green discoloration of urine caused by propofol infusion, which reversed following its discontinuation.
