What This Test Measures

This test involves growing a sample of your blood or serum/plasma in a controlled environment to detect the presence of yeast or fungal cells. If fungi are found, they can be identified further to determine the type of organism and guide treatment.

Why It’s Done

Your healthcare provider may order this test if you have symptoms like fever, chills, or signs of infection (e.g., persistent sore throat, skin rashes) that could be caused by a fungal infection. It’s also used in monitoring patients with weakened immune systems or those receiving treatments that increase infection risk.

Sample Collection and Preparation

A blood sample is taken from a vein, usually in your arm. The sample is then processed and cultured in a lab to detect fungal growth over time. Results may take several days to confirm.

What to Expect Before the Test

No special preparation is needed, but inform your provider if you’re taking antibiotics or antifungal medications, as these could affect results. Avoid eating or drinking anything for a short time before the blood draw if instructed.
