Abstract
Disclosed is a test strip for measuring medical data, in which a hydrophilic material is introduced to improve the spreadability of blood. Having the structure comprising a blood-filtering layer designed to filter off either or both of erythrocytes and low-density lipoprotein (LDL) cholesterol from an applied blood sample; a reaction layer in which the blood sample free of erythrocytes and/or low-density lipoprotein (LDL) cholesterol is reacted with an reagent, and a hydrophilic material, intercalated between the blood-filtering layer and the reaction layer, for uniformly spreading the blood sample filtered through the filtering layer, the blood-filtering layer and the reaction layer being stacked between the lower support and the upper cover, the test strip prevents the infiltration of erythrocytes into the reaction layer and improves the spreadability of blood to reduce measurement errors, thus bringing about higher reproducibility.
