Fungal culture from serum (or plasma) for identification and susceptibility testing of yeast or mold organisms

Why Is This Test Done?

Your healthcare provider may order this test if you have symptoms like fever, chills, or fatigue combined with signs of a serious fungal infection, such as organ damage or immune system issues. It’s also used in patients with weakened immune systems (e.g., from chemotherapy, HIV, or organ transplants) who are at higher risk for fungal infections.

What Does the Test Involve?

A blood sample is drawn from a vein, usually in your arm. The blood is placed in a special container that supports fungal growth. Over time, if fungi are present, they will grow and can be identified under a microscope or tested for sensitivity to different antifungal drugs.

How Long Does It Take?

Results can take several days to weeks, depending on the type of fungus and laboratory conditions. Some cultures may be positive sooner, while others require longer incubation periods.

What Are the Risks?

The main risk is from the needle insertion, which can cause mild discomfort, bruising, or a slight infection at the site. There are no other significant risks associated with the fungal culture itself.
