Explain how to test for ABO blood types?
147703
first you will need the blood sample, anti-A antibody and anti-B antibody. \nplace a drop of anti-A and anti-B antibody on separate slides.\nsmall amount of blood is taken from the patient's 4th finger. the blood sample is then mixed with the droplets of the antibodies.\nafter a few minutes, observe any signs of agglutination on the slides. if agglutination occurs on slide with anti-A antibody, the blood contains antigen A (blood type A). if agglutination occurs on slide with anti-B antibody, the blood contains antigen B (blood type B). if there's agglutination on both slides, the person has blood type AB. if there's no agglutination, the person has blood type O.

The easiest way to understand it is to look at a picture. There's one in the source link at the bottom that has a chart so you can look up both parents and find out about the child. The site also explains why ABO blood typing is not an absolutely reliable test of parenthood, and it explains how the rh factor (the + or -) works. The baby does not have to be the same as either of its parents. Be careful. A lot of people who think they understand this really don't.

hi: unfortunately the only way of finding out what blood type you are is by a simple blood test which a dr has to \norder on a requistion(piece of paper that tells the lab technician that takes your blood what tests the dr wants). \nit doesn't have to be done by your doctor only.. you can \ngo to any walk-in clinic in your neighbourhood and tell them\nyou want to know what type you are.. i am a lab technican

Yes, start with your blood type....for example 0+,\n\nnow check your siblings (brother & sisters)\nnow check your parents....and see who's blood everyone has!\n\nNow check your grandparents, and/or your aunts...if available.\nIt's amazing how many people do not know what their blood type is!

Im not gonna give you the answer but there is a really good site where you play the blood typing game then you should be able to figure it out for yourself.\nhttp://nobelprize.org/medicine/educational/landsteiner/readmore.html

(1) You can donate even without knowing your Blood Type.\n(2) Blood Group test is performed at almost every hospital. Result is obtained very shortly which allows you to know the type of yuor Blood Group.

I was told by someone (dont know it's true or not) that usually you have a blood test done to see if by some strange chance you might be related or something like. if that is true then you might have that test done. also get the test that were mention above.

By blood type, tissue type, and antibodies present.  Testing will be done on the organ to make sure it viable.

A, B, and O are the names of specific marker proteins on the blood cells.  A and B are with protiens and O is without.  Positive is indicative of yet another protein, and negative means you don't have it.  The body uses these proteins to identify the cell as 'self', to make sure it isn't a germ.  O negative blood can be accepted by anyone because it does not have any of the proteins that the body would call 'other' and attack.  It is the 'neutral' blood type. The big problem with this, though, is that people with O negative blood can only receive O negative because thier bodies would reject anything else.

male AA + female OO will produce AO that is A bloods group\nmale AO + feamle OO will produce AO and OO ,,so can be A or O group

Blood types are not evenly distributed throughout the human population. There are also variations in blood-type distribution within human subpopulations. The figures given here are for people of European descent:\n\nType Frequency\nO+ 38%\nA+ 34%\nB+ 9%\nO- 7%\nA- 6%\nAB+ 3%\nB- 2%\nAB- 1%\n\nTherefore, O+ is the most common and AB- is the rarest.

Is Your Blood Type Rare? \n\nMore recently, a number of characteristics, sometimes called markers and antigens, have been found in blood. We inherit these unique characteristics from our parents. Sometimes the process of finding compatible blood for someone with rare markers or a rare blood type is complex and challenging. Fortunately New York Blood Center has a team of world-renowned "match-makers" in our Immunohematology Lab who search for just the right compatible blood for a particular patient in need. \n\nIn fact, NYBC has the largest inventory of rare blood types in the U.S. - but we always need more rare blood. Almost everyday we receive a call from a hospital somewhere in the world trying to locate a rare blood type for a specific patient. These precise units are so rare, in fact, that we specially classify them as either "Code 99" or "Code 96" donors. Code 96 donors lack a particular combination of common markers, while Code 99 donors lack a marker nearly all other people have. Giving rare units of blood a special designation makes storage and, more importantly, retrieval of these rare units easier. That's also why we encourage donors to self-identify their ethnicity on our donor registration forms so the screening process for a rare unit of blood likely to be found within a specific ethnic group is streamlined for a patient in need.\n\nIt would be a really nice thing if you donated your blood.

AB blood group system in Humans is the co dominant type\n\nIf Ur fathers blood group is AB X Mothers ?\n                                                  |\n                                                  |\n                                             Ur's is AB \n\n Answers--->\n--------------------\n\n1. Father AB X Mother AA ----> Ur's may be AA or AB\n\n2. Father AB X Mother OA (Means A-group)      ----> Ur’s AO or BO (means all will be A-group)    \n                               \n\n3. Father AB X Mother AB ---> Ur’s AA (A-group) or AB (AB-group) or BB (B-group)\n\n4. Father AB X Mother BB ---> Ur’s AB (AB-group) or BB (B-group)\n\n5. Father AB X Mother OB  (Means B-group)             \n\n---> Ur’s OA (A-group) or AB (AB-group) or BB (B-group) or OB (B-group)\n                       \nSo, Ur mother’s might be case  1 or 3 or  4 or 5  , but not  case 2

it is very simple \nif ur blood type is o+ than u can receive blood from o+ and o-\nif ur blood type is o- than u can only receive blood from O-

Codegirl gave a great answer, although she left out the possibility of your husband being AB and giving an A to make your child AA.  All I'd add is that you have to understand the difference between phenotype (which is the expressed form) versus the genotype (with is the combination of genes).  When you and your baby were typed, they only look at the phenotype, not the genotype.\n\nA person tested as A can be genotypically AA (A from both parents) or AO (A from one parent; O, which is recessive, from the other).\nA person tested as B can likewise be BB (B from both parents) or BO (B from one parent, O from the other).\nA person tested as AB must be genotypically AB, getting one from each parent.\nA person taht is tested as O must likewise be OO, getting O from each parent.\n\nA parent gives one of their two alleles to their child.  If you are AB, you could give your child either A or B.  Since their are two possible combinations of alleles that make A (AA and AO), the father might have contributed either an A or an O.  So the only thing known for certain about the father's genotype is that he is NOT BB.  He could be either AA, AB, or AO (and contributing an A to make your child genotypically AA), or he could be either BO, OO or AO (and contributed an O to make your child genotypically AO).  But phenotypically, the father could be anything: A, B, AB, or O.

Genetic variation or differences would be the primary factor to give this question an explanation.  The same explanation that tells why there are different eye colors, different hair, different skin colors, etc. We inherit our blood type from our parents. Genes on our chromosomes tell the body what type of blood to make.\n\nThe types of proteins, glycoproteins and glycolipids found (or expressed) on the surface of red blood cells define blood types. In addition, blood types, or at least the genes responsible for them, are inherited. Karl Landsteiner described the original blood types - A, B and O - in 1900 and doctors now recognize 23 blood group systems with hundreds of different "types." Many of the blood type antigens (and the antibodies that react with them) have been discovered as a result of transfusion incompatibilities. Some of these molecules have additional functions that are at least as important as conferring compatibility (of lack of compatibility) on transfusion recipients. \n\nThere are four popularly known blood types: A, B, AB and O. These designations refer to the types of sugars (A, B and O) found on the surface of red blood cells. Everyone on the planet has an O sugar, and those who have no other type are known as blood group O. The other group names arise from the fact that some people have A, B or both A and B sugars attached to the O sugar.\n\nThe genetics is unusual in that there are two equally dominant alleles. If the gene from your mother is the recessive allele for producing O cell surface markers, and the gene from your father is for A cell surface markers, then your overall blood type is A. Why? Since everyone has O we only look at the second sugar present to determine blood type. If the gene from your mother was for B and the gene from your father was A, then your blood type would be AB. If both parents donated A alleles, then you would be A. And if both gave you recessive alleles then your blood type would be O.\n\n>> If we have the genes for the A antigen, we will make red blood cells that have A on them.\n>> If we inherit A antigen from both parents or A from one and neither A or B from the other we will have group A blood. \n>>If we inherit B antigen from both parents or B from one and neither A or B from the other we will have group B blood. \n>>If we inherit A antigen from one parent and B from the other we will have group AB blood. \n>>If we inherit neither antigen from both parents we will have group O blood. There is no O antigen. O is the result of not having any A or B. \n>>In addition to our blood group (A,B,AB,O) we can inherit the D antigen. D is more commonly know as the Rh type. This is what is called the positive or negative. Either we have it or we don't. \n>>If we inherit Rh antigen from both parents or Rh from one and not from the other we will have type positive blood. \n>>If we do not inherit the Rh antigen from either parent we will have type negative blood.\n\nThere is no much elaboration on non - ABO blood type as there is only a few who got any of the rare identified blood types.☺
