Abstract

The present invention relates to a process for preparing partial thromboplastin which comprises extracting bloodless dry placentae with an organic solvent, separating the extract from the undissolved substance, evaporating, dispersing the residue in water and adding, if desired, a stabilizer and/or lyophilizing. It further relates to the partial thromboplastin thus obtained and to its use as diagnostic agent.
