Chemotherapy readiness in pediatric oncology: Assessing an automated method to measure urine specific gravity

Abstract

As part of the evaluation for chemotherapy readiness, urine specific gravity is measured to assess the patient's overall hydration status. Depending on the accuracy of the methods used, patients may be adversely affected by having their chemotherapy delayed or prematurely started. To evaluate the diagnostic accuracy of a new automated urine dipstick readout device (Clinitek), we tested 196 consecutive urine samples for urine specific gravity and compared them with the practical gold standard, a urine refractometer. We found a high correlation between both tools among clean urine samples, but a poor correlation among the pathological urine samples.
