Abstract
A process and device for determining a hormone in a liquid such as blood wherein measured amounts of the liquid to be tested, of a radioactively-labelled hormone, and of a hormone-binding protein or antibody, all present in a measuring vial, are contacted with an adsorbing vial formed from a mixture of a thermoplastic resin and an ion exchange resin for adsorbing unbound hormone, and the residual radioactivity of the liquid mixture is then measured after draining back into said measuring vial.
