Abstract
The present invention is in the field of coagulation diagnostics and relates to a kit and method for preparing controls for use in test methods for determining thrombocyte function.
Claims7
A kit for preparing controls for a method for determining thrombocyte function, wherein the kit contains the following components:
- a. a first lyophilisate suitable for preparing a first control having normal thrombocyte function, wherein the lyophilisate consists of the following components:
- a buffer substance capable of maintaining a physiological pH, and an auxiliary substance capable of providing a cryoprotective or lyoprotective effect during lyophilization;
- and
- b. a second lyophilisate suitable for preparing a second control having abnormally reduced thrombocyte function, wherein the lyophilisate contains at least the following components:
- a buffer substance capable of maintaining a physiological pH,
- an auxiliary substance capable of providing a cryoprotective or lyoprotective effect during lyophilization, and
- a direct inhibitor of thrombocyte aggregation.

A kit for preparing controls for a method for determining thrombocyte function, wherein the kit includes:
- a first lyophilisate that is dissolvable in whole blood to produce a first control having normal thrombocyte function, wherein the lyophilisate consists of:
- a buffer substance capable of maintaining a physiological pH, and
- an auxiliary substance capable of providing a cryoprotective or lyoprotective effect during lyophilization;
- and
- a second lyophilisate that is dissolvable in whole blood to produce a second control having abnormally reduced thrombocyte function, wherein the lyophilisate includes:
- a buffer substance capable of maintaining a physiological pH,
- an auxiliary substance capable of providing a cryoprotective or lyoprotective effect during lyophilization, and
- a direct inhibitor of thrombocyte aggregation.
