Test in Focus: Comprehensive assays for chronic inflammatory demyelinating polyradiculoneuropathy (CIDP)


Confirming the diagnosis of CIDP early is critical to preventing long-term disability. However, the rare demyelinating condition is often misdiagnosed. Mayo Clinic Laboratories offers a new test that builds upon the individual NF155 test to help physicians with early diagnosis and treatment optimization.

The new test detects two antibodies — NF155 and CNTN1 — that are known to cause about 10% to 20% of CIDP cases and require different treatment than other CIDP cases. It uses two assays that are more specific and sensitive than other methodologies.
