What This Test Measures

This test involves drawing blood and growing it in a controlled environment to detect *Candida albicans* organisms. If the yeast is present, it will grow and can be identified through laboratory methods. The test does not measure yeast levels directly but confirms infection by detecting its presence.

How the Test Works

Blood is collected and placed in special containers that support fungal growth. Over time, if *Candida albicans* is present, it will multiply and can be identified by microscopic examination or further testing. Results are reported as either positive (growth detected) or negative (no growth).

When You Might Need This Test

Doctors may order this test if you have symptoms of a fungal infection, such as fever, chills, or signs of infection in other parts of the body, especially if you have a weakened immune system or recent surgery. It is also used in monitoring patients with known fungal infections.

Preparation for the Test

No special preparation is needed for this test. You may have a blood draw at a clinic, hospital, or lab. If you are on certain medications or have a history of blood infections, your doctor may advise additional precautions.

Reference range

Negative: <0.35 kU/L; Equivocal: 0.35-0.70 kU/L; Positive: >0.70 kU/L. Results expressed as Presence (Detected/Not Detected) or class score (Class 0-6)N/A

Specimen: serum

No special preparation required. Patient should inform clinician of all current medications, especially antihistamines (which generally do not affect IgE testing), recent immunotherapy, or immunosuppressive therapy that may influence results

Clinical interpretation

Frequently asked questions

Why might my doctor order this test?
Your doctor may order this test if you have symptoms of a fungal infection, a weakened immune system, recent surgery, or if you are at higher risk for bloodstream infections, such as those from a central venous catheter.
What does a positive result mean?
A positive result means that *Candida albicans* was found in your blood, indicating a fungal bloodstream infection. This requires medical attention to start appropriate antifungal treatment right away.
How long does it take to get results?
Results can take several days to a week or more, depending on the lab and the growth of the yeast. Your doctor will discuss the results with you once they are available.
