Yeast-Like Fungi, Urine — Microscopic Examination, Semi-Quantitative
A urine microscopy test that detects and estimates the amount of yeast-like fungi, which may include Candida, in a urine sample.
["Yeast-like fungi in urine can reflect contamination or a yeast infection, so the result should be interpreted with symptoms and other findings."]

What is this test?
This test examines urine under a microscope to look for yeast-like fungi, including Candida. When reported, the amount may be described using a semi-quantitative or high-power-field assessment.
Why might I need this test?
It may be ordered if you have urinary symptoms, such as painful or frequent urination, or if another test unexpectedly detected organisms or abnormal urine findings. It can also help evaluate suspected yeast infection in people with diabetes, a weakened immune system, or recent antibiotic use.
How is the test performed?
A urine specimen is examined microscopically to identify yeast-like organisms and estimate their relative quantity. The laboratory may use a stain or wet preparation and report the findings in a semi-quantitative format or per high-power field.
How do I prepare for the test?
Collect the urine as instructed by your healthcare professional, often as a clean-catch midstream sample in a sterile container. Good hand hygiene and avoiding contact with the inside of the container help reduce contamination; deliver the sample promptly when requested.
Reference range
Adult: 10-40 U/LN/A
No special preparation required. Avoid fatty meals before the test if possible.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Yeast-like fungi in urine may indicate a urinary yeast infection, particularly when symptoms are present and the result is confirmed as significant. They may also result from contamination, especially in samples collected poorly or from patients with vaginal yeast infections. Interpretation depends on symptoms, specimen quality, immune status, recent antibiotic or hospital use, and other urine-culture findings.
Short name
