    Different imaging tests may help diagnose sarcoidosis:

    • CT scan
    • Lung gallium (Ga.) scan

    Biopsies of different tissues may be done:

    • Lymph node biopsy
    • Skin lesion biopsy
    • Bronchoscopy to perform a biopsy
    • Open lung biopsy
    • Mediastinoscopy with biopsy
    • Liver biopsy
    • Kidney biopsy
    • Nerve biopsy
    • Heart biopsy

    This disease may also alter the results of the following lab tests:

    • CBC
    • Chem-7 or chem-20
    • Quantitative immunoglobulins (nephelometry)
    • PTH
    • Serum phosphorus
    • Immunoelectrophoresis - serum
    • Calcium - urine
    • Calcium - ionized
    • Calcium - serum
