Biological fluid analyzing device

A biological fluid analyzing device for analyzing biological fluid by measuring optical characteristics of a sample, comprising:

• a body comprising an upper and a lower parallel plates;
• a sample-receiving port and a pump-connection port, each defined in an outer surface of said body;
• a single fluid pathway defined between facing surfaces of said upper and lower plates, said fluid pathway fluidly connecting said sample-receiving port and said pump-connection port;
• at least one sample-treating chamber and at least one optical-measuring chamber, each chamber being defined between said facing surfaces of said upper and lower plates and each chamber defining a portion of said fluid pathway;
• and
• at least one waste liquid reservoir chamber between the sample receiving port and the pump-connection port, and connected to said pathway.
