The science of blood is simply fascinating; it began in my first year in high school and would continue throughout my life with a renewed interest with my daughter’s desire to become a forensic pathologist. My first interest was when my science teacher began teaching us the different blood types and with two parents what are the only blood type outcomes possible in the child.
What blood types are there:
- Group A – has only the A antigen on red cells and B antibody in the plasma
- Group B – has only the B antigen on red cells and A antibody in the plasma
- Group AB – has both A and B antigens on red cells but neither A nor B antibody in the plasma
- Group O – has neither A nor B antigens on red cells but both A and B antibody are in the plasma
Not every blood type can replace all other blood types, there is a certain typing or matching that has to be followed.
Donor’s and Recipient’s:
- Type O is what they call the “universal donor” and can donate red blood cells to anybody
- Type A can only donate to A’s and AB’s
- Type B only to B’s and AB’s
- Type AB can donate to other AB’s and they can receive from all the others
Blood type like many other things is inherited. with type O positive being the most common blood type, there is actually a difference in the mix based on which ethnic group your belong. You can find a great reference chat at Red Cross Blood where they offer extensive information on blood.
Some of the things that can be determined by blood testing keep us from transferring harmful things from one person to another. The following are some of those things.
- Hepatitis C virus
- Human Immunodeficiency viruses, Types 1 and 2
- Human T-Lymphotropic virus
- Syphilis (Treponema pallidum)
- West Nile virus
One of the things that had my daughter change her career path was the Casey Anthony trial. With all of the ways they collected evidence and the new technologies they used it ignited and new found interest in her. I will be her biggest fan because I continue to have a love for science in many areas but forensics is one of my greatest loves with my first being cooking and sometimes there is a science to that as well. I may not be in school studying science but I enjoy what I can on the internet, our highway to education and knowledge.
