Chapter 82. Sarcoidosis

Adjunctive Diagnostic Test

Chest x-ray is mandatory in order to recognize characteristic manifestations in the lungs, and x-ray of other organs, such as bones, may also be indicated. Calcium levels in the serum should be monitored for signs of hypercalcemia. Serum angiotensin-converting enzyme may be positive in extrathoracic sarcoidosis.
