Understanding Lab Tests for Autoimmune Disorders
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Autoimmune disorders occur when the immune system mistakenly attacks the body's own healthy cells and tissues. While there isn't a single blood test that diagnoses all autoimmune conditions, laboratory testing is fundamental for detecting immune system dysfunction, monitoring inflammation markers, and identifying specific autoantibodies that indicate various autoimmune diseases.
Recommended Test
Candida albicans Ab (IgG, IgA, IgM)
This test measures antibodies against Candida albicans, a common fungus. Elevated levels of C. albicans IgG antibodies can sometimes be associated with autoimmune disorders, as chronic infections may trigger immune system dysfunction where the body begins mistakenly attacking its own healthy cells and tissues.

The Role of Blood Testing in Autoimmune Disorders
Blood tests are essential tools for healthcare providers to assess immune system activity, detect inflammatory processes, and identify specific markers that suggest autoimmune activity. These tests help guide diagnosis, monitor disease progression, and evaluate treatment effectiveness for conditions such as rheumatoid arthritis, lupus, multiple sclerosis, and other autoimmune diseases.
Understanding the Connection
The relationship between infections like Candida and autoimmune disorders involves complex immune system interactions. Chronic or recurrent infections can potentially trigger autoimmune responses through molecular mimicry, where the immune system becomes confused and starts attacking similar-looking healthy tissue. Testing for infectious agents can provide valuable insights into potential triggers of autoimmune activity.
