What is this test?

This test examines a urine specimen under a microscope to look for yeast cells. The amount observed is reported as a semi-quantitative result based on the number seen in high-power fields.

Why might I need this test?

It may be ordered during a urinalysis, particularly when you have urinary burning, urgency, frequency, cloudy urine, or other symptoms that could be related to a urinary tract infection.

How is the test performed?

A laboratory technician examines a urine sample microscopically and records the amount of yeast observed. Results may be reported as a numerical amount, a semi-quantitative category, or the presence of yeast, depending on the laboratory method.

How do I prepare for the test?

Usually no fasting or medication changes are required. Follow your laboratory's collection instructions and provide a clean-catch, midstream urine sample when requested.

Reference range

Adult: 10-40 U/LN/A

Specimen: urine

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 occur with a yeast urinary tract infection, especially when Candida is involved. Yeast may also be introduced during collection or naturally present in the urinary tract, so a positive result is not diagnostic by itself and should be interpreted with symptoms and other urine findings.

Short name

Urinary yeast microscopy

Frequently asked questions

Does yeast in urine always mean I have an infection?
No. Yeast can sometimes reflect contamination or normal colonization rather than infection. Your clinician will interpret the result with your symptoms, examination, and other laboratory tests.
What does the high-power field result tell me?
It describes how much yeast was seen during microscopic examination. A larger amount may support concern for infection, but the result must be considered with the rest of your urinalysis.
Do I need to fast before this test?
Generally, no. Unless your clinician gives different instructions, you can usually collect urine without fasting or stopping prescribed medications.
