Apparatus and method for conducting solid phase tests for mobile components in fluids.

摘要

Apparatus and method are provided for performing solid phase tests for mobile components in fluids, especially in vitro diagnostic tests. A solid phase device is used having a fixed component immobilized on its surface which is in contact with a fluid sample when inserted therein. The improvement involves utilizing a receptacle, into which the device is inserted, having the same fixed component immobilized on the inner surface of the receptacle. The test is performed by placing a fluid sample, having a mobile component reactive with the fixed component, into the receptacle and in contact with the insert for a period of time and measuring a change which is a function of the concentration of the mobile component.
