Advantages of Dried Urine for Testing Heavy Metals & Essential Nutrients
Urine collection and shipment of the dried filter strips are simple and convenient for the patient and practitioner. Dual collections of urine directly on a filter strip,upon awakening and just before bed, are far more convenient and less subject to the inherent inaccuracies of a 24-hour urine collection, yet correlate well with 24-hour urine collections. Iodine, bromine, selenium, arsenic, mercury, cadmium, and creatinine in dried urine are exceptionally stable for weeks at room temperature allowing more flexibility in collection, shipment, testing, and storage. Elements results expressed in μg/g creatinine allows normalization of results when problems exist with urine that is very concentrated or dilute.
