ABSTRACT:
A multilayer analysis sheet for analyzing liquid samples is described, comprising, in sequence, a light transmitting hydrophobic support having on one side thereof at least one layer containing at least one reagent in a binder and a liquid sample spreading layer made of fabric, which layers are laminated to form an integral unit together with the support, wherein said fabric has the ability to supply a liquid sample placed on the surface thereof to the reagent-containing layer at a substantially constant volume per unit area, which ability is conferred upon the fabric by rendering it hydrophilic; the multilayer analysis sheet can be economically manufactured without variations in quality, and improves the spreading capability of liquid samples.
