Why does the body make antibodies against heparin?
What is this? The body makes antibodies against the Heparin because it’s binding to platelet factor 4 (a blood protein). The created antibodies will bind to the Heparin and PF4 complex, which activates the platelets. Small clots will form (hence new clots or worsening of current clots) and the platelet count falls …hence thrombocytopenia.
