A collection of devices intended to be used to collect and analyse a paediatric urine specimen for multiple clinical chemistry analytes (e.g., ketones, glucose and pH). It consists of a specimen collection undergarment (nappy or diaper) worn by the patient, and quantitative test strips for various clinical chemistry analytes. Results are analysed visually or with dedicated interpretive software (not included). It can be used at home by a caregiver and at the point-of-care by a healthcare professional. This is a single-use device.
