Additional Specimen Instructions

Rasburicase will cause enzymatic degradation of the uric acid within blood samples left at
Ambient, resulting in spuriously low uric acid levels. To ensure accurate measurements,
blood must be collected into pre-chilled tubes containing heparin anticoagulant and immediately
immersed and maintained in an ice bath. Samples must be centrifuged in a precooled
centrifuge (4°C). Finally, the plasma must be maintained in an ice bath and analyzed for
uric acid within four hours of collection
