The development of dry reagent systems has provided convenience to the user as well as devices that are more versatile and suitable for a variety of analyses. Most dry reagent chemistries are usually less than 7 cm2 by 300 micron thick packaged as discrete test devices. This reduces spoilage of unused reagents. Sample volumes needed for analysis are usually in the range of 3-30 microliter, with 10 microliter most commonly used. The use of such small volumes makes these devices suitable for neonatal and geriatric patients where large sample volumes are not often available. Hence, 150 microliter of serum (approximately 300 microliter blood) is sufficient for at least 15 different analyses on a sample. Dry reagent chemistries are easy to store, readily available for use, and disposable. Only application of a sample is needed to start an analysis.
干试剂系统的发展为用户提供了便利，同时也带来了功能更广泛、适用于各种分析的设备。大多数干试剂化学制品通常以离散测试设备的形式包装，面积小于7平方厘米，厚度为300微米。这减少了未使用试剂的浪费。分析所需的样本体积通常在3至30微升范围内，最常用的是10微升。使用如此小的体积使得这些设备适用于新生儿和老年患者，因为他们通常无法提供大量样本。因此，150微升血清（约300微升血液）足以对一个样本进行至少15种不同的分析。干试剂化学制品易于储存，随时可供使用，且为一次性使用。开始分析仅需加入样本即可。
