Description
図1に示すように、血液分析装置100は、測定部10と情報処理部20を備える。測定部10は、測定制御部11と、記憶部12と、試料調製部13と、光学検出部14と、電気抵抗式検出部15と、信号処理回路16と、を備える。情報処理部20は、処理部21と、記憶部22と、表示部23と、入力部24と、を備える。
実施形態1では、蛍光標識抗体試薬113に含まれる抗体は、CD4抗原と結合する抗体であったが、これに限らず、他の抗原と結合する抗体であっても良い。たとえば、蛍光標識抗体試薬113に含まれる抗体は、CD3抗原、CD8抗原、CD14抗原、CD19抗原、CD45抗原などに結合する抗体でも良い。
図9(a)に示すように、実施形態2では、実施形態1と比較して、試料調製部13に蛍光標識抗体試薬116を収容する容器が接続されている。蛍光標識抗体試薬116は、蛍光標識抗体試薬113と同様、血球の表面抗原を標識する。蛍光標識抗体試薬116は、光源部221から出射される光により励起されて、蛍光標識抗体試薬113とは異なる波長の蛍光を発する蛍光色素と、血球の表面抗原と結合する抗体とを有する。実施形態2の蛍光標識抗体試薬116に含まれる抗体は、CD8抗原と結合する抗体である。したがって、実施形態2では、CD8陽性T細胞の表面に発現しているCD8抗原が、蛍光標識抗体試薬116により標識される。
