What is this test?
This test examines a urine sample under a microscope to determine whether yeast cells are present. It is a qualitative test, so the result is reported as detected or not detected.
Why might I need this test?
It may be ordered when you have urinary symptoms such as burning, urgency, or frequent urination, or when yeast is suspected as a cause of a urine abnormality. It may also be used to help interpret other urine findings.
How is the test performed?
A urine specimen is collected and prepared for microscopic examination. The laboratory looks for yeast cells and reports whether they were observed.
How do I prepare for the test?
Follow the laboratory's urine collection instructions, which may include providing a clean-catch, midstream sample. Deliver the sample promptly and refrigerate it only if the laboratory specifically instructs you to do so.
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 in urine can be a normal finding or may result from contamination of the specimen. A larger amount of yeast, especially with urinary symptoms, may support a yeast infection or colonization that requires clinical evaluation. The result should be interpreted with symptoms, other urine findings, and the laboratory's comments.
