Understanding Lab Tests for Chronic Inflammatory Demyelinating Polyneuropathy
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) is a rare neurological disorder that affects the peripheral nerves, causing progressive weakness and sensory changes. While CIDP is primarily diagnosed through nerve conduction studies and clinical examination, blood tests play a crucial supporting role in monitoring inflammation and assessing the body's immune response.
Recommended Test
Interleukin-6 (IL-6), Serum
This test measures the levels of interleukin-6, a key inflammatory marker in the blood. Elevated IL-6 levels have been found in patients with Chronic Inflammatory Demyelinating Polyneuropathy, suggesting its involvement in the disease process. Monitoring IL-6 can help assess the degree of systemic inflammation and potentially guide treatment decisions.

The Role of Blood Testing in CIDP
There is no single blood test that can definitively diagnose CIDP. However, laboratory testing is fundamental for measuring inflammatory markers that may be elevated in patients with this condition. These tests help healthcare providers understand the degree of systemic inflammation and monitor treatment response over time.
Understanding Your Results
Elevated inflammatory markers like IL-6 may support the clinical diagnosis of CIDP when considered alongside symptoms and nerve function studies. However, these markers can also be elevated in other inflammatory conditions, which is why a comprehensive medical evaluation is essential for accurate diagnosis and treatment planning.
