ABSTRACT
The liver function tests show an elevated alkaline phosphatase if there are liver granulomata. Serum calcium and 24 hour urinary calcium are measured to check for high calcium and hypercalciuria. Urea and electrolytes and creatinine clearance are performed to check on renal function. Serum angiotensin converting enzyme (SACE) is elevated according to the activity of sarcoidosis. It is a non-specific test, also being elevated in other granulomatous diseases. However its elevation can be used to monitor disease activity.
