Why is this test done?

Your doctor may order this test if you have symptoms like fever, chills, or unexplained infections that could be caused by a yeast bloodstream infection. It’s also used in patients with weakened immune systems (e.g., from chemotherapy, HIV, or long-term steroids) who are at higher risk.

How is the test performed?

A small blood sample is drawn from a vein. The sample is then sent to a lab where it’s cultured to detect *Candida albicans* and, if needed, tested for how the yeast responds to antifungal drugs.

What does the test result mean?

A positive result means *Candida albicans* was found in your blood. The lab may also report the results of antifungal susceptibility testing, which helps determine the best medication to treat the infection.

What are the possible risks?

The main risk is from drawing blood, such as bruising, slight pain, or a small bruise at the site. Rarely, infections or allergic reactions can occur, but these are uncommon.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

What does a positive result mean for my health?
A positive result indicates a yeast infection in your blood, which requires medical attention. Your doctor will determine the best treatment plan based on the test results and your overall health.
How often should I get this test?
This test is typically done only when needed, based on symptoms or risk factors. Your doctor will decide if repeat testing is necessary.
Can I prevent yeast infections from appearing in my blood?
While you can’t always prevent bloodstream yeast infections, maintaining good hygiene, managing underlying health conditions (like diabetes), and avoiding excessive use of antibiotics can help reduce risk.
