I remember in science class there was a test we did to test our own blood type. Does anyone know of this test? I know I can ask my doctor but I want to find out about the test cause I thought it was stupid at the time but now I know that it would come in handy.

it is very easy to find it out . i keep teaching kids about it . the following information will help u.
What are the different blood groups?
The differences in human blood are due to the presence or absence of certain protein molecules called antigens and antibodies. The antigens are located on the surface of the red blood cells and the antibodies are in the blood plasma. Individuals have different types and combinations of these molecules. The blood group you belong to depends on what you have inherited from your parents.
There are more than 20 genetically determined blood group systems known today, but the AB0 and Rh systems are the most important ones used for blood transfusions. Not all blood groups are compatible with each other. Mixing incompatible blood groups leads to blood clumping or agglutination, which is dangerous for individuals.
Nobel Laureate Karl Landsteiner was involved in the discovery of both the AB0 and Rh blood groups.
AB0 blood grouping system
According to the AB0 blood typing system there are four different kinds of blood types: A, B, AB or 0 (null).
Do you know which blood group you belong to?
Blood typing – how do you find out to which blood group someone belongs?
A person with A+ blood receives B+ blood. The B antibodies (yellow) in the A+ blood attack the foreign red blood cells by binding to them. The B antibodies in the A+ blood bind the antigens in the B+ blood and agglutination occurs. This is dangerous because the agglutinated red blood cells break after a while and their contents leak out and become toxic.
1.
You mix the blood with three different reagents including either of the three different antibodies, A, B or Rh antibodies.
2.
Then you take a look at what has happened. In which mixtures has agglutination occurred? The agglutination indicates that the blood has reacted with a certain antibody and therefore is not compatible with blood containing that kind of antibody. If the blood does not agglutinate, it indicates that the blood does not have the antigens binding the special antibody in the reagent.
3.
If you know which antigens are in the person's blood, it's easy to figure out which blood group he or she belongs to!
What is happening when the blood clumps or agglutinates?
For a blood transfusion to be successful, AB0 and Rh blood groups must be compatible between the donor blood and the patient blood. If they are not, the red blood cells from the donated blood will clump or agglutinate. The agglutinated red cells can clog blood vessels and stop the circulation of the blood to various parts of the body. The agglutinated red blood cells also crack and its contents leak out in the body. The red blood cells contain hemoglobin which becomes toxic when outside the cell. This can have fatal consequences for the patient.
The A antigen and the A antibodies can bind to each other in the same way that the B antigens can bind to the B antibodies. This is what would happen if, for instance, a B blood person receives blood from an A blood person. The red blood cells will be linked together, like bunches of grapes, by the antibodies. As mentioned earlier, this clumping could lead to death.
Blood transfusions – who can receive blood from
whom?
People with blood group 0 are called "universal donors" and people with blood group AB are called "universal receivers."
Of course you can always give A blood to persons with blood group A, B blood to a person with blood group B and so on. But in some cases you can receive blood with another type of blood group, or donate blood to a person with another kind of blood group.
The transfusion will work if a person who is going to receive blood has a blood group that doesn't have any antibodies against the donor blood's antigens. But if a person who is going to receive blood has antibodies matching the donor blood's antigens, the red blood cells in the donated blood will clump.

Find Out Your Blood Type
2016-09-28 02:58:40 · answer #2 · answered by horam 4 · 0⤊ 0⤋
Based on the descriptions and my honest choice [usually biased] I fit AB and O with none of the negatives though my confidence may be perceived for arrogance Sun - Aquarius Moon - Aries Again bias from selection :/.... people choose what they choose and it may not be the truth also only 4 types... Dunno my actual blood type :/... but I wouldn't be surprised if it was AB or O... though that is 50% chance combined If I had to fit each to an element O = Fire or Water B = Fire + Sag + Pisces maybe Water AB = Air or Earth definitely A = Earth... specifically Virgo.... Also Fixed Signs and Water signs, probably fixed Water too These descriptions are a bit too much of each sign and not hard wired into a clear decision But again like the previous question I would say if someone had like a setup with Cancer sun Scorpio moon and lots of water with no Air and then "Got" [Chose] Sanguine... I would be like duuuuuuuuuuuude.............BS!!!!!!!!!!... Liar!! Unlike other people I'm not politically correct, I'm honest... And astrologers don't like working backwards, or saying a sign isn't more of "this, or 'that" ... I have no interest in doing that especially if it's the truth....

You probably did a test that used latex beads coated with antibody to agglutinate red blood cells. One way you could find out your blood type (and help other people in the process) is by donating blood. This will not only tell you your blood type, but some will also do cholesterol screening (I know Carter Bloodcare does this, not sure about ARC) Good luck!

Blood Type O Its kinda the opposite. I can have insensitive/ruthless/vain tendencies but it isn't a constant trait. Passionate yes, obsessive yes. Outgoing no. Warrior I can see, natural instincts are right at the surface.

Go to the doctors,they will draw some blood and then they can tell you what type your blood is. I think knowing your blood type is important.

Yeah! what you do is take a reagent that has antibodies to various blood groups ( Anti A, Anti B and Anti D) you take a drop of your the reagent so three drops one drop of each and then take a drop of blood for each reagent. mix them then look for clumping or agglutination the one that agglutinated means you have that group and the anti d indicates if your postive or negative blood group. its eazy you can ask your doctor to do it for you no biggy. hope it helped

donate blood ... they'll tell you
... tho *IF* you had teh proper reagents, you could put a drop of your blood into a solution and watch to see which
reagent caused your blood drop to clot-up and fall to the bottom or maybe top .. and thus determine blood-type .. dunno for sure, but donating blood is a fer-sure way to find out

Any doctor or blood bank will tell you.

easier way is to donate blood and you will find out for free your blood type...
