Pulmonary Renal Syndrome
Diagnosis of Pulmonary Renal Syndrome
Blood and urine tests Chest imaging Insertion of a flexible viewing tube into the lungs (bronchoscopy) with fluid wash out (bronchoalveolar lavage) Sometimes a procedure to remove a small piece of lung or kidney tissue for analysis (biopsy) Diagnosis of a pulmonary-renal syndrome requires the presence of both recurrent or persistent bleeding into the lungs (as in Diffuse Alveolar Hemorrhage ) and kidney damage ( Doctors can often diagnose diffuse alveolar hemorrhage by a person's symptoms and chest imaging findings. If the diagnosis is not clear based on symptoms and chest imaging findings (for example, if the person has not coughed up blood), doctors may need to insert a flexible viewing tube into the lungs ( Bronchoscopy ) and wash out the lungs with fluid ( The level of red cells in the blood is measured to test for anemia. Glomerulonephritis is diagnosed by symptoms, urinalysis, and blood tests of kidney function. Once a pulmonary-renal syndrome has been diagnosed, doctors try to determine the cause. They order blood tests for antibodies directed against the person's own tissues (called autoantibodies). If test results do not reveal the cause, doctors may need to remove a small piece of lung or kidney tissue for analysis (biopsy).
