摘要: Values of clinical properties are normally measured by taking a sample from patient, mixing an aliquot with reagent, placing the mixture into selected instrument, and measuring property. If another property is required, measurement sequence must be created. This can efficient on large scale, for example in centralized laboratory, but inefficient small scale. It shown that using systems based manipulation flowing streams, assays performed hand held device. flow system allows complex to remote locations automated portable instruments flexible enough conduct wide variety assays.
