A portable filter fluorometer, the hematofluorometer--which utilizes "front face" optics, internal standards, and digital computation capabilities--has been specifically designed for the rapid (approximately 5 s) assay of erythrocyte zinc protoporphyrin in unprocessed blood. A small (unmeasured) drop of blood, such as is obtained from a finger puncture, is placed on disposable cover slip and inserted in the sample holder of the instrument. The operator pushes the holder of the instrument. The operator pushes the holder, which also holds the permanent blank and standard, into the instrument. Zinc protoporphyrin concentration is automatically and instantaneously computed and the value is displayed on a digital readout as micrograms of zinc protoporphyrin per deciliter of blood for some standard hematocrit. No calibration adjustment need be performed by the operator. The hematofluorometer is designed for "field" use as well as for laboratory assays.
一种便携式滤光荧光计，即血液荧光计，它采用“前表面”光学系统、内标和数字计算功能，专门设计用于快速（约5秒）测定未经处理血液中的红细胞锌原卟啉。一小滴（未测量）血液，如通过手指穿刺获得的血液，放置在一次性盖玻片上，然后插入仪器的样品架中。操作人员将仪器的样品架推进去。操作人员将同时装有永久性空白对照和标准品的样品架推进仪器。锌原卟啉浓度会自动即时计算出来，数值以每分升血液中锌原卟啉的微克数形式显示在数字读数上，适用于某种标准血细胞比容。操作人员无需进行校准调整。血液荧光计既设计用于“现场”使用，也适用于实验室检测。
