Candida albicans Antibodies (IgG, IgA, IgM) Test
This test measures IgG, IgA and IgM antibodies to Candida albicans in a blood serum sample. Clinicians use the antibody levels, often compared between an earlier and a later draw, to help evaluate a possible fungal infection.
About this test
Candida albicans is a fungus that can cause candidiasis, an infection Quest describes as ranging from localized to systemic disease, with severity that varies widely, including cases that can be serious. This test measures three classes of antibody the immune system makes in response to the organism — IgG, IgA and IgM — all from a single blood serum sample, analyzed using an enzyme-linked immunosorbent assay (ELISA).
Because antibody levels can change as an infection develops, the test is sometimes ordered more than once: an earlier sample and a later, convalescent sample, so a clinician can compare the two and look for a rising or falling pattern rather than reading a single result alone.
Who might consider this test?
- People who talk with their clinician about this test are often being evaluated for a possible fungal infection and its course.

Additional details
What this test looks at
The test reports three separate antibody values from the same serum sample: IgG, IgA and IgM antibodies to Candida albicans. Together they describe the immune system's antibody response to the organism, measured with an ELISA method.
Order online and a physician order is included — no doctor's visit and no insurance needed. Your sample is collected at a Quest Diagnostics patient service center.
Laboratory results should always be interpreted by a licensed clinician who knows your health history. This page is information about a test, not medical advice.
Frequently asked questions
What does this test measure?
It measures three types of antibody the immune system may make in response to Candida albicans — IgG, IgA and IgM — all from a single blood serum sample analyzed with an ELISA method.
How is the sample collected?
Through a routine blood draw; the test uses a small serum sample collected at a Quest Diagnostics patient service center.
Do I need to prepare for this test?
No preparation instructions are listed for this test, though people follow any instructions their ordering clinician provides.
Why might this test be ordered more than once?
Quest describes comparing antibody titers between an earlier, acute sample and a later, convalescent sample, which lets a clinician look at how the levels are changing over the course of an illness rather than relying on one result.
Can I get the Candida Albicans Antibodies test without a doctor's visit or insurance?
Yes. The $120 cash price includes an independent physician's order, so no referral is needed, and insurance is never involved.
