Blood cake (hematology)

Blood cake is the name given to the gelatinous mass that is formed from red blood cells , platelets and fibrin during blood clotting (i.e. when samples are taken without the addition of anticoagulants) in a blood sample tube and slowly settles (sediments). The blood serum is separated out. By centrifugation , i.e. H. through controlled, accelerated sedimentation, blood cake (sediment) and blood serum (supernatant) can be separated from one another more quickly. This is a laboratory method to get the maximum amount of blood serum from a minimal blood sample.

In the preparation of pudding , the blood is with a whisk pitched to a polymerization of fibrin and hence the formation to prevent a blood clot.
