Abstract
The present invention provides a coated article, which can be used in in-vitro diagnostics, in particular in the diagnostic testing of body fluids, such as in blood coagulation testing. The coated article is made of a polymer material and coated with a polymer material, which may be the same or different. The present invention furthermore provides a method of preparing such a coated article and a method of performing such diagnostics, e.g. coagulation analysis.
Claims16
A pair of first and second disposable articles adapted for use in a viscoelastic measurement apparatus for measuring coagulation characteristics of a blood sample, the first and second disposable articles being adapted to move with respect to each other, a volume being defined between surfaces of the first and second disposable articles, the volume adapted to receive the sample of blood, each of the first and second disposable articles comprising:
- (a) an article body made of a polymer material, the polymer material comprising a first polymer, and
- (b) a coating material layer, distinct from the article body, disposed on the surfaces defining the volume adapted to receive the sample of blood, the coating material layer comprising a coating material selected from the group consisting of a second polymer, a resin, and combinations thereof, the coating material layer being configured to adhere to a fibrin network during coagulation of the blood sample;
- wherein,
- (i) the first disposable article is a measurement cup,
- (ii) the second disposable article is selected from the group consisting of a pin and a sleeve for a pin, and
- (iii) the measurement apparatus is selected from the group consisting of a thromboelastography measurement apparatus and a thromboelastometry measurement apparatus.
