Understanding Lab Tests for Acute Candida Infection
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Acute Candida infection is caused by an overgrowth of Candida fungi, particularly Candida albicans, which can affect various parts of the body including the mouth, throat, genital areas, and in severe cases, the bloodstream. While some Candida infections can be diagnosed through visual examination or culture tests, blood antibody testing provides valuable information about the body's immune response to the infection.
Recommended Test
Candida albicans Ab (IgG, IgA, IgM)
This comprehensive antibody test measures three types of antibodies against Candida albicans. IgM antibodies are particularly important as they are the first antibodies produced in response to an infection, and elevated IgM levels may indicate a current or recent acute Candida infection. IgG and IgA antibodies provide additional information about chronic or recurrent infections.

How Blood Testing Helps Diagnose Candida Infections
When the body encounters Candida organisms, the immune system produces specific antibodies to fight the infection. Testing for these antibodies, particularly IgM antibodies which are produced first during an acute infection, can help healthcare providers determine if a current or recent Candida infection is present, especially when other diagnostic methods may be inconclusive.
Understanding Your Test Results
Elevated IgM antibodies typically suggest an active or recent infection, while elevated IgG antibodies may indicate a past infection or chronic exposure. IgA antibodies are often associated with mucosal infections. Your healthcare provider will interpret these results in conjunction with your symptoms and clinical presentation to determine the most appropriate treatment approach.
