margin-bottom: 0px; max-width: 100%; word-wrap: normal; min-height: 1em; white-space: pre-wrap; box-sizing: border-box !important; line-height: 1.75em;"><br  /></p><p style="margin-top: 0px; margin-bottom: 0px; max-width: 100%; word-wrap: normal; min-height: 1em; white-space: pre-wrap; box-sizing: border-box !important; line-height: 1.75em;">一、仪器的性能</p><p style="margin-top: 0px; margin-bottom: 0px; max-width: 100%; word-wrap: normal; min-height: 1em; white-space: pre-wrap; box-sizing: border-box !important; line-height: 1.75em;"><br  /></p><p style="margin-top: 0px; margin-bottom: 0px; max-width: 100%; word-wrap: normal; min-height: 1em; white-space: pre-wrap; box-sizing: border-box !important; line-height: 1.75em;">对于检验产品，特别是五分类血球仪而言，最关键的性能就是准确性和稳定性。市面上五分类血球仪种类众多，从检测原理分主要有以下几种：</p><p style="margin-top: 0px; margin-bottom: 0px; max-width: 100%; word-wrap: normal; min-height: 1em; white-space: pre-wrap; box-sizing: border-box !important; line-height: 1.75em;">1、体积、电导和激光散射技术；</p><p style="margin-top: 0px; margin-bottom: 0px; max-width: 100%; word-wrap: normal; min-height: 1em; white-space: pre-wrap; box-sizing: border-box !important; line-height: 1.75em;">2、电阻抗、射频和核酸荧光染色技术；</p><p style="margin-top: 0px; margin-bottom: 0px; max-width: 100%; word-wrap: normal; min-height: 1em; white-space: pre-wrap; box-sizing: border-box !important; line-height: 1.75em;">3、激光散射和细胞化学染色技术；</p><p style="margin-top: 0px; margin-bottom: 0px; max-width: 100%; word-wrap: normal; min-height: 1em; white-space: pre-wrap; box-sizing: border-box !important; line-height: 1.75em;">4、双鞘流和细胞化学染色技术；</p><p style="margin-top: 0px; margin-bottom: 0px; max-width: 100%; word-wrap: normal; min-height: 1em; white-space: pre-wrap; box-sizing: border-box !important; line-height: 1.75em;">5、多角度偏振激光散射技术</p><p style="margin-top: 0px; margin-bottom: 0px; max-width: 100%; word-wrap: normal; min-height: 1em; white-space: pre-wrap; box-sizing: border-box !important; line-height: 1.75em;">；6、多角度激光散射技术。</p><p style="margin-top: 0px; margin-bottom: 0px; max-width: 100%; word-wrap: normal; min-height: 1em; white-space: pre-wrap; box-sizing: border-box !important; line-height: 1.75em;"><span style="line-height: 1.75em; font-size: 16px;">目前，大家对不同原理的五分类仪器检测结果争议很大，主要围绕嗜酸性粒细胞与嗜碱性粒细胞结果是否准确进行讨论。俗话说，实践是检验真理的唯一标准。对五分类检测结果心存疑虑的购买者可以在购买前选用可靠的第三方质控品对仪器进行检测或查看其临检中心室间质评的测评结果。</span><br  /></p><p style="margin-top: 0px; margin-bottom: 0px; max-width: 100%; word-wrap: normal; min-height: 1em; white-space: pre-wrap; box-sizing: border-box !important; line-height: 1.75em;"><br  /></p><p style="margin-top: 0px; margin-bottom: 0px; max-width: 100%; word-wrap: normal; min-height: 1em; white-space: pre-wrap; box-sizing: border-box !important; line-height: 1.75em;">二、光源</p><p style="margin-top: 0px; margin-bottom: 0px; max-width: 100%; word-wrap: normal; min-height: 1em; white-space: pre-wrap; box-sizing: border-box !important; line-height: 1.75em;"><br  /></p><p style="margin-top: 0px; margin-bottom: 0px; max-width: 100%; word-wrap: normal; min-height: 1em; white-space: pre-wrap; box-sizing: border-box !important; line-height: 1.75em;">激光是五分类血球仪的常用光源。通常是激光直接照射细胞，或对细胞染色后再用激光照射，通过检测不同角度散射光的强度进行白细胞五分类。由于激光具有单色性和高强度的特点，用其作为光源的仪器分类结果肯定比使用卤素灯或LED灯的结果好。市面上的血球仪大多采用激光作为光源。</p><p style="margin-top: 0px; margin-bottom: 0px; max-width: 100%; word-wrap: normal; min-height: 1em; white-space: pre-wrap; box-sizing: border-box !important; line-height: 1.75em;"><br  /></p><p style="margin-top: 0px; margin-bottom: 0px; max-width: 100%; word-wrap: normal; min-height: 1em; white-space: pre-wrap; box-sizing: border-box !important; line-height: 1.75em;">目前使用的激光种类主要有半导体激光和气体激光。二者比较半导体激光具有寿命长（7—10年）、体积小、启动快、耗电少、对稳压要求低，更为经济适用等特点，虽然其功率相对较低，但对细胞分类而言其强度已经足够；气体激光功率强，但使用寿命短，需要定期更换，维护成本会相对较高。</p><p style="margin-top: 0px; margin-bottom: 0px; max-width: 100%; word-wrap: normal; min-height: 1em; white-space: pre-wrap; box-sizing: border-box !important; line-height: 1.75em;"><br  /></p><p style="margin-top: 0px; margin-bottom: 0px; max-width: 100%; word-wrap: normal; min-height: 1em; white-space: pre-wrap; box-sizing: border-box !important; line-height: 1.75em;">三、检测模式</p><p style="margin-top: 0px; margin-bottom: 0px; max-width: 100%; word-wrap: normal; min-height: 1em; white-space: pre-wrap; box-sizing: border-box !important; line-height: 1.75em;"><br  /></p><p style="margin-top: 0px; margin-bottom: 0px; max-width: 100%; word-wrap: normal; min-height: 1em; white-space: pre-wrap; box-sizing: border-box !important; line-height: 1.75em;">如果实验室里没有三分类血球仪而直接购买五分类，那么购买的五分类一定要具备CBC+5Diff（白细胞五分类）模式和CBC（体检）模式。通常情况是进行CBC+5Diff即白细胞五分类模式的检测；但是部分体检，例如入职体检、入户体检等，只需要做白细胞计数而不需要进行五分类检测，采用CBC模式即可完成。雷杜五分类血球仪Hemaray 86就具备这两种检测模式，而且其CBC模式只需要10μL血样，CBC+5Diff模式仅需20μL，节省样本的同时也节省试剂。</p><p style="margin-top: 0px; margin-bottom: 0px; max-width: 100%; word-wrap: normal; min-height: 1em; white-space: pre-wrap; box-sizing: border-box !important; line-height: 1.75em;"><br  /></p><p style="margin-top: 0px; margin-bottom: 0px; max-width: 100%; word-wrap: normal; min-height: 1em; white-space: pre-wrap; box-sizing: border-box !important; line-height: 1.75em;">四、检测项目</p><p style="margin-top: 0px; margin-bottom: 0px; max-width: 100%; word-wrap: normal; min-height: 1em; white-space: pre-wrap; box-sizing: border-box !important; line-height: 1.75em;"><br  /></p><p style="margin-top: 0px; margin-bottom: 0px; max-width: 100%; word-wrap: normal; min-height: 1em; white-space: pre-wrap; box-sizing: border-box !important; line-height: 1.75em;">用户购买血球仪，主要看有什么要求，要解决什么问题？一般综合医院门诊使用，选择常规的五分类血球仪足以满足需求；若是儿科或血液科的专用仪器，就要选择具备幼稚细胞、异常淋巴细胞、网织红细胞等检测功能的血球仪。</p><p style="margin-top: 0px; margin-bottom: 0px; max-width: 100%; word-wrap: normal; min-height: 1em; white-space: pre-wrap; box-sizing: border-box !important; line-height: 1.75em;"><br  /></p><p style="margin-top: 0px; margin-bottom: 0px; max-width: 100%; word-wrap: normal; min-height: 1em; white-space: pre-wrap; box-sizing: border-box !important; line-height: 1.75em;">五、样本处理能力</p><p style="margin-top: 0px; margin-bottom: 0px; max-width: 100%; word-wrap: normal; min-height: 1em; white-space: pre-wrap; box-sizing: border-box !important; line-height: 1.75em;"><br  /></p><p style="margin-top: 0px; margin-bottom: 0px; max-width: 100%; word-wrap: normal; min-height: 1em; white-space: pre-wrap; box-sizing: border-box !important; line-height: 1.75em;">用户在购买前一定要了解清楚所在单位的检测样本量，有多大的头就戴多大的帽。仪器买贵了或者样本处理能力达不到需求都是件揪心的事。</p><p style="margin-top: 0px; margin-bottom: 0px; max-width: 100%; word-wrap: normal; min-height: 1em; white-space: pre-wrap; box-sizing: border-box !important; line-height: 1.75em;"><br  /></p><p style="margin-top: 0px; margin-bottom: 0px; max-width: 100%; word-wrap: normal; min-height: 1em; white-space: pre-wrap; box-sizing: border-box !important; line-height: 1.75em;">六、售后服务</p><p style="margin-top: 0px; margin-bottom: 0px; max-width: 100%; word-wrap: normal; min-height: 1em; white-space: pre-wrap; box-sizing: border-box !important; line-height: 1.75em;">常言道：救人如救火。对五分类血球仪也是一样，机器损坏待修时间过长会造成病人对医院的信任度下降，久而久之就会造成病人的流失。所以，机器的售后服务也是一个必须考虑的因素。</p><p style="margin-top: 0px; margin-bottom: 0px; max-width: 100%; word-wrap: normal; min-height: 1em; white-space: pre-wrap; box-sizing: border-box !important; line-height: 1.75em;"><br  /></p><p style="margin-top: 0px; margin-bottom: 0px; max-width: 100%; word-wrap: normal; min-height: 1em; white-space: pre-wrap; box-sizing: border-box !important; line-height: 1.75em;">通过以上对五分类血球仪的了解，相信您一定能够买到令自己满意的仪器！</p><p style=""><img src="http://mmbiz.qpic.cn/mmbiz/rz7R73cuHRrv6jdOCoJeZmYwvEAIoHpY0a7yJL2egiaEokLTpwkIsIRTzTFUic09aEThKHS4hrEcSqU0lAS3tu5g/0" data-ratio="0.14784394250513347" data-w="487" width="auto" width="auto" src="http://mmbiz.qpic.cn/mmbiz/rz7R73cuHRrv6jdOCoJeZmYwvEAIoHpY0a7yJL2egiaEokLTpwkIsIRTzTFUic09aEThKHS4hrEcSqU0lAS3tu5g/0" style="word-wrap: break-word !important;
