Urinalysis (UA) is a division of clinical laboratory, which includes the physical, chemical and microscopic examination of urine. Dipstick format is used for most of the in-house urinalysis chemical tests.

The sample must be fresh (not chemically preserved), well mixed, and room temperature to obtain the best results. The containers of urine dipstick should not be refrigerated, must be stored at room temperature in airtight containers. The common dipstick tests that are routinely performed on random urine specimens include,

Protein
