Special Instructions

Microscopic examination of the urine sediment is automatically performed if the protein, blood, leukocyte, or nitrate is positive. SPECIMEN COLLECTION: One to two ounces (30-50 milliliters) of urine–a sufficient sample is required for accurate results; sometimes you may be directed to collect a sample using a “clean-catch” technique: women should spread the labia of the vagina and clean from front to back; men should wipe the tip of the penis. Start to urinate, let some urine fall into the toilet, then collect one to two ounces of urine in the container provided, then void the rest into the toilet.
