What Does This Test Measure?
The test looks for specific antibodies in your blood that your immune system produces in response to *Candida albicans*. Antibodies are proteins that help your body recognize and fight infections. This test is not used to diagnose an active infection but can indicate past exposure or immune response.
Why Might You Need This Test?
Your healthcare provider may recommend this test if you have symptoms like persistent mouth or throat infections, skin rashes, or other signs of fungal exposure, especially if you have a weakened immune system (e.g., from HIV, chemotherapy, or other conditions). It can also be part of monitoring for certain chronic conditions.
How Is the Test Performed?
A small blood sample is drawn from a vein in your arm. The sample is sent to a lab where it is tested for the presence of antibodies against *Candida albicans*. The results are compared to a reference range to determine if antibodies are present.
What Do the Results Mean?
A positive result means your body has produced antibodies against *Candida albicans*, suggesting past exposure or an immune response. A negative result means no detectable antibodies were found. Results alone do not confirm an active infection and should be interpreted by your healthcare provider in the context of your symptoms and medical history.
