What is the Anti-GBM Test?

The Anti-GBM Test detects antibodies directed against the glomerular basement membrane, a key structure in the kidneys. These antibodies can cause inflammation and damage to the kidneys and, in some cases, the lungs. The test is commonly used to diagnose Goodpasture’s syndrome, a rare autoimmune disorder affecting kidney and lung function.

Who should take this test?

• Patients with suspected Goodpasture’s syndrome.
• Individuals with blood in urine (hematuria) or kidney dysfunction.
• Patients with symptoms like coughing blood (hemoptysis).
• People with rapidly progressive kidney disease.
• Doctor-advised evaluation of autoimmune kidney disorders.

Preparation & Test Process

How to interpret results

The test identifies the presence of Anti-GBM antibodies in the blood.

Positive result suggests autoimmune conditions such as Goodpasture’s syndrome affecting the kidneys and lungs.
Negative result indicates that Anti-GBM antibodies were not detected.

Results should be interpreted along with clinical symptoms, kidney function tests, and other investigations.
