if you donate blood they will tell you what type you have. if you've already had blood taken some time in the past, your dr. may know from a previous test. you may be able to just ask him.

You can't know your blood type from your parents blood type unless they are both O negative. Any other combination would make your type uncertain. For example, if both were O Positive, they could carry the negative and you could be O negative. If they were both A positive, you could potentially be A+, A-, O+ or O- .
To determine your type a blood sample is required. It only has to be a few drops if the testing reageants are available.
If you donate a unit of blood, you will do a good deed and they will tell you your type.

Depends on what your parents' blood types are.
If both parents are O, then you can only be O.
If either parent is AB, then you can NOT be O.
Everything else pretty much needs to be determined by blood test, because the possible combinations of your parents' genes mean that you could be any of the four types - A, B, AB, or O.
But you'll still need to know whether you're Rh-positive or Rh-negative.
If you've ever given blood, ask the blood bank - they have to type it.

There are only so many blood types. If you don't want to go to a doctor, or pay for a test, you can donate blood at your local Red Cross and find out.

if you really want to know, read about dominant and recessive gen in biology/genetics. but for a short:
case 1:parents (O and O)
children must be O, otherwise, there's a big chance you are adopted :)
case 2:parents (A and O) or (A and A)
children might be A or O
case 3:parents (B and O) or (B and B)
children might be B or O
case 4:parents (A and B)
the children have all the possibilities, A, B, AB, O
case 5:parents (AB and O)
the children might be A or B
case 6:parents (AB and A)
the children might be A or AB
case 7:parents (AB and B)
the children might be AB or B
case 8:parents (AB and AB)
the children might be A or AB or B

You have to go to a doctor or the red cross to be typed. You could have a completely different type from either of your parents.

If both your parents are O, you're O.
If one of your parents is AB, you're not O.
After that, you need a blood test.

You will need to go somewhere & give a sample.
Why don't you donate blood to the Red Cross, at least once.
You'll learn your type & possibly save someone's life.
If you're at least 18 years old.

Everybodys bllod type is different, just go to your doctor, and they will cross match you, and you will know your blood type.

well, if both parents are the same, then you will be that blood type... if one is a and one is b than you can be either.... etc etc...
