Understanding Lab Tests for Candidiasis
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Candidiasis is a fungal infection caused by Candida species, most commonly Candida albicans. While superficial infections like thrush or vaginal yeast infections are typically diagnosed through clinical examination and direct testing methods, blood tests play a valuable role in detecting systemic infections and assessing the body's immune response to chronic or recurrent Candida infections.
Recommended Test
Candida albicans Ab (IgG, IgA, IgM)
This comprehensive antibody test measures three types of antibodies (IgG, IgA, and IgM) against Candida albicans. High levels of IgG antibodies particularly suggest a chronic or recurrent Candida infection, as these antibodies are produced by the immune system to fight off the infection over time. The test helps identify both recent infections (IgM) and long-term immune responses (IgG), providing valuable insight into the duration and severity of Candida exposure.

The Role of Blood Testing in Candidiasis
Blood tests for candidiasis primarily measure antibodies that your immune system produces in response to Candida exposure. These tests are particularly useful for identifying chronic infections, recurrent episodes, or systemic candidiasis that may not be apparent through other diagnostic methods. Antibody testing helps healthcare providers understand the extent and duration of Candida exposure.
Understanding Your Results
Elevated antibody levels may indicate current or past Candida infections, but results must be interpreted alongside clinical symptoms and other diagnostic findings. Your healthcare provider will consider your complete medical picture when determining the most appropriate treatment approach.
