[The plasma coagulation system of domestic cats]

Haemostaseological investigations of the animals need improvement. Usual methods in human medicine have to be reconsidered with regard to their qualification for veterinary medicine. A standardization of methods and accurate haemostaseological characterization of the reagents used are necessary for an appropriate interpretation of the results and interlaboratory comparative studies. Results of global tests (ARZ, PTT, TZW, TZ, RZ) and determinations of activity of single blood clotting factors (I, II, V, VII-XII) in healthy cats are presented and discussed in view of the mentioned.
