CPT® Code 81007

The CPT® Code 81007 refers to a specific laboratory test known as a urinalysis, which is designed to screen for the presence of bacteriuria, or bacteria in the urine, without utilizing culture or dipstick methods. This test is particularly significant as bacteriuria can indicate the presence of an acute or chronic urinary tract infection (UTI). The procedure begins with the collection of a urine sample, which can be obtained through various methods such as clean catch, mid-stream void, or catheterization. Once the sample is collected, it is thoroughly mixed and then diluted using fluorescent staining dyes to enhance the visibility of the components within the urine. The analysis is conducted using automated flow cytometry, a sophisticated technique that allows for the precise measurement of different cellular elements in the urine. During this process, the urine sample is passed through a sheath and illuminated by an argon laser beam. This advanced technology enables the counting and recording of various components, including red blood cells, white blood cells, epithelial cells, casts, and bacteria. The qualitative results generated from this urinalysis provide valuable information regarding bacterial concentrations, which can be instrumental in diagnosing urinary tract infections. Overall, this procedure is a critical tool in the clinical assessment of urinary health and the identification of potential infections.
