A biological test strip is disclosed and includes a source end, at least one test line and at least two control lines. The source end is used for dropping a sample liquid thereon. The at least one test line is used to react with at least one sample of the sample liquid to generate a colorization reaction. The at least two control lines, are used to react with the sample liquid to generate at least two colorization reactions with different color darkness, so as to define a predetermined maximum concentration value and a predetermined minimum concentration value, both of which can be used as color comparison references for the at least one test line.
