Cryptococcosis
Diagnosis of Cryptococcosis
Culture and examination of a sample of tissue or fluid To diagnose cryptococcosis, a doctor takes samples of tissue and body fluids, such as cerebrospinal fluid, sputum, urine, and blood, to be cultured and examined. A Spinal Tap (lumbar puncture) is done to obtain cerebrospinal fluid (the fluid that surrounds the brain and spinal cord). Blood and cerebrospinal fluid may be tested for certain substances released byCryptococcus.
