Why This Test Is Done

Your doctor may order this test if you have symptoms like fever, chills, or unexplained low blood pressure, especially if you have a weakened immune system, recent surgery, or a central line (like a port or catheter). It’s also used in people with prolonged hospital stays or conditions like diabetes or cancer that increase infection risk.

How the Test Works

A small sample of your blood is drawn and placed in special containers that support the growth of yeast. These containers are then incubated for several days to see if *Candida* bacteria grow. If they do, it confirms a fungal blood infection.

What to Expect Before the Test

You may feel slight discomfort at the needle insertion site, but it’s usually over quickly. Avoid eating or drinking for a short time before the test if instructed, but this isn’t always required.

What to Expect During the Test

The blood sample is taken from a vein in your arm or hand. You might feel a brief pinch, but it’s a quick procedure. The site may bruise slightly afterward.

Frequently asked questions

A positive result means *Candida* yeast is growing in your blood, which can be life-threatening if untreated. It often requires antifungal medications. A negative result means no yeast was detected, but other infections or conditions may still be causing your symptoms.
This test is critical for diagnosing bloodstream fungal infections, which can be hard to detect without testing. Early treatment improves outcomes, especially in high-risk patients.
How long does it take to get results?
Results can take several days to a week, depending on lab processes. Your doctor will contact you once they have the findings.
Can I eat or drink before this test?
Check with your doctor first, as dietary restrictions may vary. Generally, no special preparation is needed unless instructed otherwise.
