Evaluation of the handy type electrolyte analyzer Fingraph
Journal Title: Journal of Analytical Bio-Science - Year 2013, Vol 36, Issue 4
Abstract
Fingraph is a handy-sized electrolyte analyzer for measuring Na and K ion concentration in blood (including whole blood, serum and plasma). The special features of this instrument is giving results in 60 seconds by using a disposable sensor-card and only a drop of blood (10μL) from finger-tip. The coefficient of variations (CV%) were less than 2.0% and 3.0% for Na and K respectively when measuring ISE-CRS. The correlation factors (r) for both Na and K were above 0.95 when measuring whole blood (heparin lithium added) with Fingraph and electrolyte analyzer STAX-3, and measuring serum with Fingraph and automated analyzer TBA-120FR. It is expected useful for reducing painfulness and stress of patients facing frequent vein blood drawing, and reducing TAT (turn around time) when applied for outpatients and inpatients at bedsides of hospitals and clinics.
