Basic examination of procalcitonin reagent that used AQT90FLEX

Abstract

The results of the basic examination of AQT as a target reagent by immunochromatography were mostly good. For N = 50, the rate of agreement is 88.0%, and it is considered that the introduction of AQT to routine examination is possible in all six mismatched cases, which depend on individual differences in visual observation. In addition, the rate of agreement with the blood culture was 75.0%, and only a small number of samples is required, but the positivity rate of the blood cultures tended to be high if the PCT level was high. Because we can measure whole blood samples immediately without preprocessing a specimen, which is a characteristic of AQT, a quick result report is possible. In addition, without individual differences occurring in comparison with the immunochromatography method, which requires complicated visual judgment and quantitative measurement, human errors, such as input mistakes, can be prevented because AQT can be applied online.
