Abstract：
The use of portable hemoglobin measuring devices is widespread. In this context, the company HemoCue® has put on the market a new device, the Hb801. It uses a whole blood absorbance measurement method and not the azidmethemoglobin measurement method used by HemoCue\'s older devices. We evaluated this new equipment on EDTA venous blood. Hb801 is lightweight, compact, requires a volume of 10 μL of blood and renders its result in less than a second. The repeatability and intermediate precision are close to the values expected according to Ricos, with coefficients of variation respectively for a low level of hemoglobin: 2.1% and 1.9%, for an average level: 0.8% and 1.5% and for a high level: 1.5% and 1.3%. Comparison to our laboratory reference method (XN-10 Sysmex®) and HemoCue® Hb201+ was performed on 96 samples. Bias (SD) found were: XN-10: +0.42 g/dL (0.17), HemoCue® Hb201+: +0.17 g/dL (0.41). Clinically acceptable performance (within ± 1 g/dL of reference hemoglobin) was high: 93.8%. In the end, this device seems to us to be suitable for hemoglobin point-of-care testing.
摘要：
便携式血红蛋白测量装置的使用是广泛的。在这种情况下，HemoCue®公司已将一种新设备投放市场，Hb801它使用全血吸收率测量方法，而不是HemoCue的旧设备使用的叠氮高铁血红蛋白测量方法。我们在EDTA静脉血上评估了这种新设备。Hb801是轻量级的，紧凑型,需要10μL的血液体积，并在不到一秒的时间内呈现其结果。重复性和中间精度接近Ricos的预期值，低水平血红蛋白的变异系数分别为2.1%和1.9%，平均水平：0.8%和1.5%，高水平：1.5%和1.3%。对96个样品进行与我们的实验室参考方法(XN-10Sysmex®)和HemoCue®Hb201+的比较。发现的偏差（SD）为：XN-10：0.42g/dL（0.17），HemoCue®Hb201+:+0.17g/dL(0.41)。临床可接受的性能(在参考血红蛋白的±lg/dL内)很高:93.8%。最后,在我们看来，这种装置适用于血红蛋白即时检测。
