• Reagent composition, dry element and method for determination of total bilirubin
  申请人：EASTMAN KODAK COMPANY (a New Jersey corporation)

  公开号：EP0158507A2

  公开（公告）日：1985-10-16

  A reagent composition, dry analytical element and an assay to determine total bilirubin in aqueous liquids use a diazonium salt, or reagents capable of producing a diazonium salt when contacted with water, and 3,3-dimethylglutaric acid or a salt thereof present in an amount effective to buffer the assay at a pH of 3.5 or less. The composition and elements described herein provide a means to eliminate the effect of an undetermined interferent which is either preformed or formed in situ in diazo-based total bilirubin determinations of biological fluids (e.g. uremic serum).

  一种用于测定水性液体中总胆红素的试剂组合物、干燥分析元件和测定法，使用重氮盐或与水接触后能生成重氮盐的试剂，以及 3,3-二甲基戊二酸或其盐，其含量能有效缓冲 pH 值为 3.5 或更低的测定法。本文所述的组合物和元素提供了一种消除未确定干扰物影响的方法，这种干扰物是在生物液体（如尿毒症血清）的重氮基总胆红素测定中预先形成或在原位形成的。
• Integral multilayer analysis element

  公开（公告）日：1988-08-17

  Disclosed is an integral multilayer analysis element comprising in order, first at least one reagent layer and second a porous spreading layer laminated on a light-transmissive water-impermeable support, wherein a fluorine-containing surfactant is incorporated at least in said spreading layer. The element is especially suitable for clinical examination of an aqueous liquid sample of a human humor such blood, lymphatic liquid, saliva, urine, etc. By the incorporation of the F-containing surfactant, the spreadable area can be controlled over a broad range of the spotting amount of a sample liquid without interfering with the metering function of the spreading layer.

  本发明公开了一种整体多层分析元件，依次包括第一层至少一个试剂层和第二层多孔铺展层，铺展层层压在透光不透水的支撑物上，其中至少在所述铺展层中加入了含氟表面活性剂。该元件特别适用于对血液、淋巴液、唾液、尿液等人体液体样本进行临床检查。通过加入含氟表面活性剂，可涂抹面积可在较大范围内控制样本液体的涂抹量，而不会影响涂抹层的计量功能。
