Predicting A Future Property Using Reagents by Measuring Properties at Points in Time

A method for measuring specific substances and extracting objective information from the measurements that is especially applicable in immunoassays but can also be used in other assays which rely on affinity between binding partners. The invention overcomes problems and difficulties caused by disturbing or interfering phenomena by exploiting a mathematical algorithm which predicts the target value from a series of measurements performed during the reaction. The mathematical method of linear prediction is used for this purpose.
