複雑で大きなものとなることが多い。However, when blood is collected from the human body and analyzed for specific components using an analyzer, various pretreatments such as separation of blood cell components are required.
In many cases, analysis-inhibiting substances are removed, a specific If11 plasma region is fractionated, and the results are measured using an analyzer. During this pretreatment, correct analytical results often cannot be obtained because the sample becomes contaminated or the target component disappears or changes with the passage of time due to coexisting components. Furthermore, the operation of subjecting the collected blood to pretreatment is complicated, and the pretreatment device itself is often complex and large.
