Critical Value:  
Interpretive Comments: Analysis includes macroscopic examination and chemical examination for protein, blood, glucose, ketones, specific gravity, nitrite, leukocytes and blood.

Results from any unrefrigerated urine sample >2 hours may not be accurate.

A microscopic examination is done only when the urine is less than 2 hours old.
A urine microscopic examination will not be performed on samples giving a normal dipstick result.
(Except research requests).

Microscopic reference range:

Some erythrocytes, leukocytes and casts are excreted by normal individuals, but they are seen only occasionally in urinary sediments examined microscopically.
* <5 Red Blood Cells per high power field are considered normal
* <5 White Blood Cells per high power field are considered normal
* Occasional Hyaline Casts per high power field are considered normal
