Description
本願は、2005年12月29日に出願した米国仮特許出願第60/755,014号の優先権を主張する。
本発明は、一般的には、サンプル分析装置(sample analyzer)に関し、更に特定すれば、操作が簡単で、誤った結果を提示する危険性を低減したサンプル分析装置に関する。
{SSALSi, SFALSi} -> {drbci, CHCi}
270に示すように、散乱SSALSiおよびSFALSiの強度が所定の検出閾値以下である場合、制御をステップ268に戻す。しかしながら、散乱SALSiおよびSFALSiの強度が所定の検出閾値よりも大きい場合、制御をステップ272に移す。ステップ272では、SSALSiおよびSFALSiの合計が所定の血小板閾値よりも大きいか否か判定を行う。SSALSiおよびSFALSiの合計が所定の血小板閾値よりも大きくない場合、粒子「i」が血小板であると判定し、制御をステップ274に移す。ステップ274では、計数した血小板の数(Nplt)を1だけ増分し、制御を再度ステップ268に移す。
Vdisp =εδ(π/4)d3
貯蔵空洞の直径は、次の式から推定することができる。
d = ((4Vdisp/(εδπ))1/3
図9gの表は、分析を4分間行い、その半分をRBCの測定、半分をWBCの測定に費やすと仮定した場合に、サンプル推進流体および試薬の各々に適当と思われる、貯蔵空洞の直径を纏めた。球体化溶液およびシース溶液用のカード上試薬貯蔵空洞のサイズは、十分な大きさのカードについて考慮するとよい。
以上、少なくとも1つの例示的な例に関して、本発明について説明したが、本明細書を読めば、多くの変形や修正が当業者には明白となろう。したがって、添付した請求項は、従来技術に鑑み、かかる変形および修正を全て含むようにできるだけ広く解釈するものとすることを表明する。
