What Is This Test Measuring?
The test detects specific antigens produced by *Candida albicans*, a type of yeast that can cause infections in various parts of the body. These antigens are released when the yeast grows out of control, which can occur in weakened immune systems or after certain medical treatments.
Why Might Your Doctor Order This Test?
Your doctor may recommend this test if you have symptoms like fever, fatigue, or signs of infection (such as white patches in the mouth or throat) and have a history of fungal infections, a weakened immune system, or recent medical procedures that increase risk.
Who Is at Higher Risk?
People with compromised immune systems (e.g., due to HIV/AIDS, chemotherapy, or organ transplants), those on long-term antibiotics, or those with diabetes or other chronic illnesses may be at higher risk for *Candida* infections.
What Does a Positive Result Mean?
A positive result suggests the presence of *Candida albicans* antigens in your blood, which may indicate an active fungal infection. Further testing or treatment may be needed to address the infection.
