Abstract
An improved method for performing an in vitro diagnostic test is provided. The method utilizes a solid phase device having a fixed component immobilized on its surface which is in contact with a fluid sample when inserted therein. The improvement resides in 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.
