Understanding Lab Tests for Mixed Cryoglobulinemia
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Mixed cryoglobulinemia is a type of vasculitis (blood vessel inflammation) characterized by the presence of abnormal proteins called cryoglobulins in the blood. These proteins can precipitate in cold temperatures and cause inflammation in small and medium-sized blood vessels. While the condition itself is diagnosed through specialized blood tests for cryoglobulins, identifying the underlying cause is crucial for effective treatment.
Recommended Test
Hepatitis C Viral RNA, Quantitative Real-Time PCR
This test detects and measures the amount of active Hepatitis C virus in the blood. Since Hepatitis C infection is the primary cause of mixed cryoglobulinemia, identifying ongoing viral replication is crucial for confirming the underlying trigger of this vasculitis condition. The quantitative measurement also helps guide antiviral treatment decisions.

The Connection Between Hepatitis C and Mixed Cryoglobulinemia
Hepatitis C virus (HCV) infection is the most common cause of mixed cryoglobulinemia, accounting for approximately 80-90% of cases. The chronic viral infection triggers an immune response that leads to the production of these abnormal proteins. Testing for active Hepatitis C infection is therefore essential when mixed cryoglobulinemia is suspected or diagnosed.
Why This Testing is Important
Identifying active Hepatitis C infection in patients with mixed cryoglobulinemia is essential because successful antiviral treatment can often resolve or significantly improve the vasculitis symptoms. Without treating the underlying viral infection, managing mixed cryoglobulinemia becomes more challenging and may require immunosuppressive therapies.
