DiGeorge Syndrome
Diagnosis of DiGeorge Syndrome
Blood tests Sometimes imaging tests (such as chest x-rays and echocardiography) Doctors suspect DiGeorge syndrome based on symptoms. Blood tests are done for the following reasons: To determine the total number of blood cells and the number of T and B cells To evaluate how well T cells and the parathyroid gland are functioning To determine how well the body produces immunoglobulins in response to vaccines A chest x-ray may be taken to check the size of the thymus gland. Because DiGeorge syndrome often affects the heart, Echocardiography and Other Ultrasound Procedures is usually done. Echocardiography uses high-frequency sound (ultrasound) waves to produce images of the heart and thus can detect abnormalities in the heart's structure, such as a birth defect. Genetic tests may be done to look for abnormalities.
