Understanding Lab Tests for Chronic Candida infection
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Chronic Candida infection is a persistent fungal condition caused by Candida species, most commonly Candida albicans. Unlike acute infections, chronic Candida can be challenging to diagnose through conventional methods, making specialized blood tests essential for detection and monitoring.
Recommended Test
Candida albicans Ab (IgG, IgA, IgM)
This comprehensive antibody test measures three types of immune responses to Candida albicans: IgG, IgA, and IgM antibodies. Elevated IgG levels particularly indicate chronic or past Candida infection, as these antibodies are produced by the immune system in response to Candida exposure and can persist even after active infection has been treated. The test provides crucial information for diagnosing ongoing fungal infections that may not be detected through other methods.

Diagnosing Chronic Candida Infection
Chronic Candida infections often present with vague symptoms that can mimic other conditions, including fatigue, digestive issues, and recurrent infections. Blood tests that measure specific antibodies produced by the immune system in response to Candida exposure provide valuable diagnostic information for identifying ongoing or past infections.
Understanding Antibody Testing
The Candida antibody test measures different types of immune responses: IgM antibodies typically indicate recent or acute infection, IgA antibodies suggest mucosal involvement, and IgG antibodies indicate chronic exposure or past infection. This comprehensive approach helps healthcare providers understand the timeline and severity of Candida exposure.
