If your doctor suspects sarcoidosis, he or she will do the following:
Review your medical history
Perform a physical exam
Order chest X-rays and blood tests that may aid in the diagnosis
In 90% of people with sarcoidosis, chest X-rays show abnormalities. Many patients also have a low white blood cell count. Your doctor may also order pulmonary-function tests, which measure how well your lungs are working. Tissue biopsies (tests on small tissue samples) from your lungs may be done to look for other diseases, such as fungal infection or lymphoma (cancer of the lymph system), which may resemble sarcoidosis on a chest X-ray.

Symptoms of sarcoidosis vary depending on the area of the body involved, and may be mild, moderate, severe, or absent. The first symptoms are often vague and may include the following:
Shortness of breath
The lungs are usually the first area to be affected by sarcoidosis: 9 of 10 people with sarcoidosis have some type of lung involvement. Pulmonary sarcoidosis can be serious, leading to the formation of scar tissue...
Many people with sarcoidosis have mild symptoms and do not require any treatment. Often, the disease gets better on its own. However, for patients with more pronounced symptoms, corticosteroid drugs, such as prednisone, or other immunosuppressive medications, are the recommended therapy. The main goals of treatment are to keep the patient comfortable by reducing symptoms and to maintain proper functioning of any affected organs. At this time, there is no treatment available to reverse the pulmonary fibrosis (scarring in the lungs) that may accompany severe sarcoidosis.
