There is provided the reagent layer composition that can substantially reduce the measurement bias arising from hematocrits. The addition of fatty acid (4-20 carbons) and quaternary ammonium salt to a commonly used reagent layer composition composed of an enzyme, an electron transfer mediator, and several water soluble polymers not only reduce the hematocrit level-dependent bias but also provide very stable performance for an extended period of time. Disclosed are also various types of sub microliter sample volume electrochemical biosensors that are suitable to use with the reagent layer composition of present invention.

Electrochemical biosensor

There is provided electrochemical biosensors with a sample introducing part, comprising a sample introducing passage, an air discharge passage, and a void. The sample introducing passage communicates with the air discharge passage, and the void is formed at the point of communication. Also, disclosed is the electrochemical biosensor with the said sample introducing part and a fluidity determining electrode.
