General
Synonym/Acronym:
Urate.
Common Use:
To monitor uric acid levels during treatment for gout and evaluation of tissue destruction, liver damage, renal function, and monitor the effectiveness of therapeutic interventions.
Specimen:
Serum (1 mL) collected in a red- or tiger-top tube. Plasma (1 mL) collected in a green-top (heparin) tube is also acceptable. Note: Rasburicase will rapidly decrease uric acid in specimens left at room temperature. If patients are receiving this medication, collect the blood sample in a prechilled green-top (heparin) tube and transport in an ice slurry.
Normal Findings:
