How to Find out Your Blood Type

Why Find Out Your Blood Type

The discovery of human blood groups was made in 1901 by the famous Austrian scientist Dr. Karl Landsteiner. He won the Nobel Prize for his discovery.

He divided the blood group into four categories being A, B, AB, O . His discovery made him understand that two distinct chemical molecules called antigens and antibodies were present on the surface of the red blood cells. He found that if these categories were not matched properly it could cause clumping or agglutination in the arteries and veins of the recipient and lead to a bad reaction that could sometimes even result in loss of life.

Under the common ABO blood typing process, a person's blood type could be A, B, AB or O. It is very important to know your own blood type, as well as the blood type of your spouse and children. Important decisions concerning emergency blood transfusions may have to be made quickly, so having this information on hand for medical professionals can shave precious minutes off the initial triage process following a trauma.

 

What is My Blood Type

  1. The first and best place to go to get your blood type is a teaching institution with a nursing program. Students learning to become nurses need people to practice on. Relax, they have practiced on each other quite a few times. You can get cholesterol levels, glucose, hematocrit, and you will find out your blood type.
  2. Donating blood is a generous and valuable opportunity when answering the question,"What blood type am I?"  You will find out your blood type and be tested for HIV and Hepatitis.
  3. Your college infirmary may be able to help determine your blood type. Ask your school infirmary for the dates volunteer nurses will be in town. Every few months nurses visit to distribute free STD screening kits.
  4. How can i find out what blood type i am without having to give up any blood? Contact the hospital where you were born. They may still have the records of your blood type. If you have ever delivered a baby, or had any surgical procedure, chances are your hospital records will help to find out your blood type.
  5. Check with a Biology instructor. Biology 101 usually includes a self-testing exercise for blood typing, as standard curriculum.
  6. How to find out your blood type at home? A simple and affordable blood typing test can be performed literally anywhere by anyone through the use of specially-treated testing cards.

What Determines which Blood Type a Person has?

One of the main factors that determine blood type is family genetics. A child receives separate sources of genetic code called alleles from each parent at the time of conception. One of the alleles located on chromosome 9 contains the precise blood type of the donor parent, and is classified as A, B, AB or O. An additional factor is called the Rhesus factor, which could be positive or negative. The actual blood type of a child is determined by the dominant blood type between the two parents. A and B are both dominant over O, which means a child that receives an A blood type from the father and an O blood type from the mother will have blood type A.

Subsequently, A and B are considered to be codominant, which means a child inheriting an A blood type from the mother and a B blood type from the father will most likely have an AB blood type. Only two recessive O blood type genes from both parents will result in a child having an O blood type. An O negative blood type is considered to be a universal donor, since it contains nothing which would appear foreign to someone else's blood type. Those with A or B positive blood types must not receive blood infusions of the opposite type, since the body's natural defenses will attack the incoming blood cells as they would any other infection.

A person's blood type is determined through a simple ABO test available at a doctor's office, blood donation center or even through pharmacies. A drop of blood is placed on two separate testing circles marked A and B. The card has already been prepared with dried serum containing anti-A and anti-B chemicals. If the blood reacts to the A circle but not the B circle, then the tester's blood type is considered to be A. A reaction to both circles indicates an AB blood type, while a complete non-reaction to either circle indicates an O blood type. The reaction is caused by the chemicals on the card coming in contact with type A or type B antigens on the surface of the red blood cells. Anti-A reacts with an A blood type and Anti-B reacts with a B blood type.
