Understanding Lab Tests for Mucosal Candida Infection
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Mucosal Candida infections are fungal infections that affect the mucous membranes, commonly occurring in areas such as the mouth (oral thrush), throat, and vaginal regions. These infections are caused by an overgrowth of Candida species, particularly Candida albicans.
Recommended Test
Candida albicans Ab (IgG, IgA, IgM)
This comprehensive antibody test measures three types of immune responses to Candida albicans. IgA antibodies are particularly important as they are primarily found in mucosal areas and elevated levels may suggest an active Candida infection in areas such as the mouth, throat, or vagina. IgG and IgM antibodies provide additional information about past exposure and current immune response to the infection.

Diagnosing Mucosal Candida Infections
While mucosal Candida infections are often diagnosed through clinical examination and microscopic analysis of samples from affected areas, blood tests can provide valuable supporting evidence by measuring the body's immune response to the infection. Antibody testing helps detect the presence of specific immune markers that indicate exposure to and potential active infection with Candida organisms.
Understanding Your Results
Elevated antibody levels, particularly IgA, can indicate an active mucosal Candida infection or recent exposure. However, results should always be interpreted in conjunction with clinical symptoms and other diagnostic findings. Some individuals may have detectable antibodies without active infection, while others with compromised immune systems may not produce adequate antibody responses.
Important Considerations
