The iQ 200 System is intended for analysis of urine chemistry, specific gravity, and formed sediment elements, which constitutes typical routine urinalysis.
Urinalysis is ordered by physicians as a screening procedure for detection of possible abnormal metabolic or systemic disease, indicated by chemical composition of urine, and of potential renal or urinary tract disease or dysfunction, indicated by urine concentration and by the nature and distribution of urinary formed elements. Urine profile testing is commonly employed in the initial clinical evaluation of patients admitted for hospital care or undergoing physical examinations.
Routine urinalysis is also indicated in diagnosis of patients with possible renal or urinary tract infection, carcinoma, or other injury, as well as for monitoring the status and effectiveness of drug, radiation, or dietary therapy, and of post-surgical or post-therapeutic recovery.
The information produced by the iQ 200 System concerning the composition of patient urines is ordered at the discretion of the physician, and is part of a larger body of laboratory and other test results available to assist the physician in health assessments or differential diagnoses. Routine urinalysis findings are always subject to judgment and interpretation by physicians relative to the patient's overall clinical presentation and history.
Indications for use as stated in the FDA summary.
