Abstract

혈중 글루코스 함량 측정기에 사용하기 위해 시약 시험 스트립이 채용된다. 전혈 시료는 스트립 상의 매트릭스의 한쪽 표면에 적용되고, 측정기는 약 635nm와 700nm에서 매트릭스의 반대 표면의 반사율을 측정하고, 반사율로부터 시료 중의 글루코스 농도를 계산한다. 적용된 시료가 매트릭스를 투과해서 시험 표면에 나타나는 부위는 700nm에서 감지할 수 있는 범위까지 흡수하지 않는다. 그럼에도 불구하고, 글루코스를 함유한 시료는 시약을 함유한 매트릭스의 성분들과 상호작용하여 혈액 색의 효과를 나타내는 700nm에서의 반사율의 변화를 일으킨다. 그 결과, 광학적으로 볼 수 있는 헤모글로빈의 존재 중의 전헐 시료 중의 글루코스 농도를 측정하는 측정기에 스트립이 사용될 수 있다.
