Yeast and Hyphae, Urine — Microscopic Examination
A urine microscopy test that looks for yeast cells and fungal hyphae, which may occur with a urinary tract infection or specimen contamination.
["Yeast or hyphae in urine can suggest a fungal urinary infection, but contamination and other causes may also produce these findings."]

What is this test?
This test examines a urine sample under a microscope to look for yeast cells and hyphae. Hyphae are branching, thread-like structures produced by fungi.
Why might I need this test?
It may be ordered when symptoms suggest a urinary tract infection, when yeast is suspected, or as part of the laboratory review of an abnormal urine test. The results can help identify a possible fungal cause of infection.
How is the test performed?
A urine specimen is collected and examined microscopically for the presence of yeast and fungal hyphae. Other urine findings, such as bacteria, white blood cells, or signs of inflammation, may be reported at the same time.
How do I prepare for the test?
Follow the laboratory's urine-collection instructions, which may request a clean-catch, midstream sample. Before collecting urine, clean the genital area and avoid contaminating the sample with creams or other products.
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 and hyphae in urine may be associated with a Candida urinary tract infection, particularly in people with diabetes, an immune system condition, urinary catheterization, or other risk factors. These findings can also result from contamination of the urine specimen, so they must be interpreted with symptoms and other urine or culture results.
