Abstract: This invention concerns a biochip kit, comprising at least one biochip with at least one reactor, in which probe antibody and probe antigen are immobilized non-randomly in the form of probes array or/and probes pattern. This invention also concerns a method for testing a biological sample by using the kit. This kit can be used to analyze different target molecules corresponding to said probe antibody and probe antigen. By using this kit, the reactor number and the detection time needed for the analysis are reduced while the detection comparability is increased. So this kit has the advantage of being economical, timesaving and more efficient.
