Critical Value:  
Interpretive Comments: Levels are elevated in gout, with increased metabolism of nucleoproteins, such as in leukemia (especially after chemotherapy) and polycythemia, or after the intake of foods rich in nucleoproteins, such as liver. Plasma levels are increased with decreased renal function. The limit of solubility of uric acid in blood is 400 µmol/L. The risk of gout increases above this level.
