The U of T researchers took an existing population of mostly young and healthy adults who provided detailed information about their usual diets and provided fasting blood that was used to isolate DNA to determine their ABO blood type
and the level of cardiometabolic risk factors, such as insulin, cholesterol and triglycerides.
In particular, when considering ABO blood type
antigens, non-0 blood is correlated with the highest risk of CVD.
Beyond the ABO blood type
and the Rhesus (Rh) blood type, the International Blood Transfusion Society recognizes twenty-eight additional blood types with names like Duffy, Kidd, Diego and Lutheran.
This type of delta check does not catch errors when the patient does not have a historical blood type, nor does it identify instances in which 2 patients have the same ABO blood type
(ie, silent WBIT).
To examine whether ABO blood type
and factor V Leiden clotting factor are associated with preeclampsia risk, the researchers reviewed data from a national registry of blood types of pregnant women and a national registry of medical records.
