Evaluation of laboratory tests as a guide to diagnosis and therapy of myositis.
Plasma CK concentrations have been widely used as the primary muscle enzyme marker for diagnosis and progression of myositis. Recently, total CK and CK-MB serum concentrations have been compared to, and used in conjunction with, serum concentrations of aspartate aminotransferase in diagnosis of myositis. The algorithmic use of CK, AST, and aldolase plasma concentrations to diagnose and categorize patients with myopathy may be a useful method of diagnosing specific muscle disease without invasive procedures. CAIII, as a specific marker for skeletal muscle damage, may replace CK as the enzyme of choice in diagnosis and progression of myositis and other muscle disease. Additional studies are required to determine the usefulness of carbonic anhydrase for the diagnosis and assessment of myositis.
