Blood testing unit

摘要

A blood constituent separating membrane constituted substantially of polysulfone membrane separates blood plasma and/or blood serum from a blood sample. Reagents which are supported on the reagent layer have a portion for spreading the blood plasma and/or the blood serum separated from the blood sample, and when the reagent layer comes into contact with the blood constituent separating membrane, the blood plasma and/or the blood serum spreads over the reagent layer. The reagent forms a color as a result of a reaction with the blood plasma and/or the blood serum.
