Understanding Lab Tests for Proliferative Glomerulonephritis
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Proliferative glomerulonephritis is a serious kidney condition characterized by inflammation and abnormal cell proliferation within the glomeruli, the kidney's filtering units. While the definitive diagnosis typically requires kidney biopsy and imaging studies, blood tests play a crucial supporting role in monitoring disease activity and guiding treatment decisions.
Recommended Test
PCNA Antibody, IFA
This test measures antibodies against Proliferating Cell Nuclear Antigen (PCNA), which can indicate active autoimmune processes affecting the kidneys. In proliferative glomerulonephritis, elevated PCNA antibody levels may suggest ongoing inflammation and cell proliferation within the glomeruli, helping to monitor disease activity and guide treatment decisions.

The Role of Blood Testing in Glomerulonephritis
There isn't a single blood test that directly diagnoses proliferative glomerulonephritis itself. However, blood testing is fundamental for assessing autoimmune activity, monitoring inflammation markers, and evaluating the body's immune response that may be contributing to kidney damage. These tests help healthcare providers understand disease progression and treatment effectiveness.
Understanding Your Results
PCNA antibodies are associated with autoimmune conditions that can affect kidney function. Elevated levels may indicate active disease processes, while monitoring changes in antibody levels over time can help assess treatment response and disease progression. Your healthcare provider will interpret these results alongside other clinical findings and tests.
Important Considerations
