Abstract
The accuracy of a diagnostic test for determining the coagulability of blood is improved by reducing the interference by heparin. At least one metal salt, preferably a copper or zinc salt, is added to the diagnostic test to avoid or considerably reduce the undesirable influence of heparin on the test.
Claims14
A method of reducing the interference by heparin with the accuracy of a diagnostic test for determining the coagulability of blood, which comprises introducing an additive into at least one reagent of said diagnostic test, wherein said additive comprises at least one metal salt of copper or zinc, a copper or zinc ion of which forms a bond with heparin.
