| 摘要 |
The invention generally relates to devices, systems and methods adapted for use by patients for monitoring their own dietary intake of sodium without any need of laboratory facilities or collection of blood samples. The systems utilize test strips for measuring the concentration of analytes in urine, specifically, chloride and creatinine. Urinary chloride concentrations, normalized by creatinine concentrations to reduce variability contributed mainly by changing states of hydration serve as a conveniently monitored surrogate for salt intake by subjects, especially patients with hypertension or congestive heart failure who must control their salt intake carefully.
