Abstract

The effect of prior cumulative mixing was evaluated by means of a simple regression model which used as a dependent variable percentage(%) change of each repeated observed value for the initial value. The red blood cell count (RBC), hematocrit (Hct), and mean corpuscular volume(MCV) showed a significant decrease (p<.01), but % of basophils had a significant increase (p<.05). The ratios of rate of change (regression coefficient/SD) were .0012 for RBC, .0020 for Hct, .0024 for MCV, and .0011 for % of basophils. Of the 19 parameters evaluated, 21% changed.

자동혈구분석기(Technicon $H^*2$ )에 의한 혈액검체의 측정전 mixing횟수가 검사결과에 미치는 영향을 평가하기 위하여 19가지 parameter를 대상으로 초기측정치에 대한 반복측정치의 변화율을 종속변수로 하여 단순회귀분석을 실시하였다. Mixing횟수가 증가할수록 RBC, Hct, MCV는 통계적으로 유의하게 (p< .01)감소하였고, 호염기구 백분율은 유의하게(p< .05)증가하였으므로 평가된 19가지 parameter의 21%인 4가지 검사항목에서 변화가 있었다.
