Healthsens Nephropoc® is the one of the most reliable devices available in the market today for determining the concentration of creatinine in peripheral blood. It also estimates the eGFR, fundamental for evaluating renal disease; the more accurate the creatinine measurement is, the more accurate the estimation of the eGFR will be.
To confirm its reliability, the Healthsens company undertook a performance evaluation study of the Nephropoc® device by comparing it to the laboratory analyser Cobas 8000 Roche® (compensated kinetic Jaffe) and the IDMS reference method (Isotope Dilution Liquid Chromatography−Tandem Mass Spectrometry).
In this comparison, it is worth mentioning that the blood fraction measured by the different devices is not the same. While the Cobas 8000 Roche® system and the IDMS require extracting the serum from the blood, the Healthsens Nephropoc® system is capable of directly measuring total blood, which allows the immediate analysis of a blood sample after its extraction.
As a summary of the performance evaluation the following conclusions are presented:
- Although these previously mentioned reference methods can only measure the concentration of serum creatinine, which eases the measuring process as many impurities are removed, Healthsens Nephropoc® provides similarly consistent results despite being real-time measurements and carried out with total blood.
- The reliability of this device is further supported by the fact that the results of the measurements carried out by patients coincide with those made by experienced personnel.
- All these evaluations have been carried out by official institutions external to the Healthsens company; the Nephropoc®´s characteristics have been properly verified and validated.
The main benefits of Healthsens Nephropoc® lie in the possibility of estimating renal function in a minimum amount of time, using just a drop of blood obtained by a painless finger puncture procedure. Reliability, simplicity and ease of use enable Healthsens Nephropoc® to be used:
- By the patient himself, for the control and monitoring of his renal function.
- In primary care services (outpatient services, clinics).
- In conjunction with imaging studies that involve the use of iodinated contrasts, which can cause acute renal function disorder.
- In emergency services, when the quick evaluation of renal function is necessary.
