Reference values vary based on several factors, including the specific laboratory that supplies them. A patient's urine test values should be interpreted based on the reference value of the laboratory in which the test was done; the laboratory typically provides these values with the test result. These values are listed in alphabetical order in the following table.

Normal findings detected by microscopic examination can include a few RBCs (especially in menstruating women), WBCs, epithelial cells, bacteria, yeast cells, crystals (eg, calcium oxalate, triple phosphate, amorphous phosphates and urates), sperm, and unidentifiable materials. Large amounts of these substances or the presence of certain other materials may be abnormal.
