A few weeks ago I noticed an article on the mainstream news about blood type and heart disease. The data came from the Nurses Health Study which has been going on so long the researchers are signing up the participant’s family members. The problem with blood type is there are far more people with type O and A than AB and B. The smaller numbers skews the percentages. In this article http://todayhealth.today.com/_news/2012/09/16/13866976-blood-type-hype-may-be-overblown#comments that point is expanded on.
There is another point made in the article I don’t agree with. First, I want to be clear that I do agree that a person should know their blood pressure, because its the single best factor a person can control for good health. Reece Carson, the protagonist, in Body Wave even tells one of her clients how important knowing and controlling blood pressure is to her health. However, I don’t agree with the article when it states knowing your cholesterol level is more important than knowing your blood type. Really?
The same argument given for not needing to know your blood type could fit with not needing to know your cholesterol level. Both require blood tests ordered by doctors while a blood pressure reading does not.
If people know their blood type is O-the universal donor because their Rh factor is negative, they can go immediately to give blood should a disaster occur because they know they can help out. Secondly, how would blood donation centers that give blood to hospitals to save lives function without the good people that donate blood and yes, know their blood type? Most blood is donated by repeat donors.
Sexually active women should be aware of their Rh factor, which is usually tested at the same time as blood type. Rh factor is important to be aware of in case a miscarriage occurs. With easy access to home test pregnancy kits, women without insurance and possibly scared teenagers, may not see a doctor as quickly as other women. Some times Mother Nature steps in and the pregnancy ends before a doctor is seen. An Rh-female, who doesn’t know she’s Rh-, will have no idea she’s building up antibodies that could effect her next pregnancy. She could lose the window to receive the Rh vaccine because articles like this one suggests that testing for blood type which includes identifying Rh factor isn’t important. I think all women should know their blood type and Rh factor for this very reason.
Whenever a person donates blood, their blood type and Rh factor can be learned and every baby born is tested as well. Mothers should start recording their newborn’s blood type and Rh factor in their birth albums so it can be easily referenced.
