Abstract:
A real-time, non-invasive system and method for determining the level of an analyte of interest in the urine of a patient is disclosed. The system and method uses the measured level of an analyte of interest to detect the onset of acute renal failure (ARF) as early as possible to prevent that patient from developing the disease or mitigating the effects of the disease. The system and method may be used to monitor the recovery of a patient after an ARF diagnosis. Preferably, the analyte of interest is creatinine or urea. The system may be placed in the urine drain line of a patient between a Foley catheter or other urinary drain and a urine collection bag. The system makes substantially continuous measurements of the urine flow rate and the concentration of the analyte of interest to determine the mass excretion rate of the analyte so it may be monitored to detect if the patient experiences a delta change in the mass excretion rate of an analyte that is indicative of the onset of ARF or a change in renal function.
