The serum anti-GBM (glomerular basement membrane) test is used to diagnose a group of autoimmune diseases called anti-GBM disease or Goodpasture syndrome, which can cause kidney and lung damage.
When this test is required
The test is usually requested when a person shows symptoms of kidney or lung damage, or when there is suspicion of anti-GBM disease or Goodpasture syndrome.
What the Test Detects
The test measures the level of antibodies against the glomerular basement membrane (GBM), which is a part of the kidney and lung tissue. The presence of these antibodies can indicate anti-GBM disease or Goodpasture syndrome.
Preparation for the Test
There is no specific test preparation needed. However, it is recommended to inform the healthcare provider about any medications being taken before the test.
Sample Requirements
The test requires a blood sample, which is usually drawn from a vein in the arm.
Additional Notes
Anti-GBM disease or Goodpasture syndrome is a rare condition, but it can cause serious kidney and lung damage if left untreated. It is recommended to discuss the test results with a healthcare provider for further guidance and treatment options.
