Fungal culture and sensitivity (from a fluid specimen)
This test checks for the presence of fungi in your body fluids and determines how your body might respond to treatment. It helps identify infections caused by yeast or mold.

What Is Fungal Culture & Sensitivity Testing?
A sample of your bodily fluid (like blood, urine, or cerebrospinal fluid) is collected and examined under a microscope to look for fungal organisms. If fungi are found, the sample is grown in a lab to confirm their presence and identify the specific type.
Why Is This Test Done?
Your healthcare provider may order this test if you have symptoms like persistent fever, unusual skin rashes, or unexplained infections that don’t improve with antibiotics. It’s also used in people with weakened immune systems, those receiving chemotherapy, or those with chronic illnesses like diabetes.
How Is the Test Performed?
A small sample of your fluid is taken via a needle, catheter, or other method. The sample is then sent to a lab where it’s cultured to grow fungal organisms, if present. Sensitivity testing helps determine the best antifungal medication.
What Do the Results Mean?
Positive results show the presence of fungi, and the lab report will specify the type. Sensitivity results indicate which antifungal drugs are most effective against that fungus, guiding treatment decisions.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Clinical Significance: Fungal infections can be serious, especially in vulnerable populations. Early identification through culture and sensitivity helps prevent complications and ensures targeted treatment, improving recovery chances.
