Abstract
Summary
The rate of coagulation of whole blood in paraffin coated or lusteroid tubes after addition of a standard suspension of cephalin, gives a rapid and reliable estimation of the anticephalin activity of the corresponding plasma. The extent of the difference between the rate of coagulation of blood in glass and lusteroid tubes supplies an additional estimate of this activity. The response to the clot accelerating action of cephalin does not seem to be significantly affected by the platelet content of the blood; the presence of hypoprothrombinemia may, however, exaggerate the delay in the response.
