Evaluation of new Smart Strip instrument for determination of hemoglobin

「Summary」 Before a blood donation for a suitable donor, items are checked as pleasant, safe, and convenient as possible. Among these items are blood specific gravity (SG) or whole blood hemoglobin concentration (Hb conc.). Though the former had long been adopted because of its low cost, the latter is now mainly adopted for a donor's health control. However, the only instrument for determination of Hb conc. was HemoCue Hb 201+ based on colorimetry. However, a new mobile instrument (called Smart Strip) based on amperemetry has been developed. With this instrument, the interference from other blood components was eliminated. Smart Strip was suited for the determinations of Hb at concentrations between 1-20g/dL. Its within-run precision (C.V.) was 2.6%. A close correlation was found between Smart Strip and other instruments.
