Urinalysis, Complete, with Reflex to Culture

Test Code: 3020

CPT Code(s): 81001

Clinical Significance: Dipstick urinalysis is important in accessing the chemical constituents in the urine and the relationship to various disease states. Microscopic examination helps to detect the presence of abnormal urine cells and formed elements. Culture may identify the organism(s) causing infection.

Includes: Macroscopic and Microscopic Examinations - A culture is performed, when appropriate, at an additional charge (CPT code(s): 87088, 87086).

Test Code: 10553

CPT Code(s): 87880

Includes: If Streptococcus Group A Rapid Antigen is negative, a culture will be performed at an additional charge (CPT code(s): 87081).

Methodology: Immunochromatography Bacterial Culture, Aerobic Routine Isolation and Identification Procedures

Clinical Significance: A positive result from the antigen assay or isolation of Group A streptococci by culture from a symptomatic patient is usually considered clinically significant.
