Understanding Lab Tests for Autoimmune Disorders
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Autoimmune disorders occur when the body's immune system mistakenly attacks healthy cells and tissues. These complex conditions often require specialized blood tests to detect specific antibodies and markers that indicate abnormal immune system activity.
Recommended Test
Candida albicans Ab (IgG, IgA, IgM)
This test measures antibodies against Candida albicans, a common yeast. In some cases, elevated levels of these antibodies, particularly IgG, may be associated with autoimmune disorders. This occurs when the immune system becomes overactive and begins producing antibodies not only against infections but also mistakenly against the body's own healthy cells and tissues.

How Blood Tests Diagnose Autoimmune Disorders
Blood tests are fundamental tools for diagnosing autoimmune disorders because they can detect the presence of autoantibodies - antibodies that target the body's own tissues. These tests help healthcare providers identify which specific autoimmune condition may be present and monitor disease activity over time.
Understanding Your Results
Autoimmune disorder testing often involves multiple markers and requires careful interpretation by healthcare professionals. Elevated antibody levels may indicate immune system dysfunction, but results must be evaluated alongside symptoms and other clinical findings for accurate diagnosis.
