I've read that HCG shows up in blood before it spills over into the urine. I think you could probably get a positive on an hpt and get a negative on a blood test, because most labs have a certain cutoff point to show pregnancy. Some cut off at 10 some at 25-50. Go to the doc and he can order a quantitative test to tell the exact amount of HCG you have in your blood.
Negative blood can be given to someone with positive blood. Positive blood CANNOT be given to someone with negative blood.
There is no blood type OE. There are 8 different blood types, A positive and negative, B positive and negative, O positive and negative, and AB positive and negative.
No, an O Positive person cannot donate to an A Negative person because the person who is Negative, or Rh Negative, will react to the Positive (Rh Positive) blood. Negative can only get Negative, Positive can get Positive or Negative.
Human blood has a protein (rH). If you have rH in your blood you have positive blood type, if you are lacking rH you have a negative blood type. Negative blood rejects positive blood because it is lacking the chemical, however positive blood can accept both negative or positive blood.
Negative feedback usually regulates hormone concentrations in the blood.
Is the clotting of blood an example of positive or negative feedback?
CAN TWO POSITIVE BLOOD TYPES MAKE a negative blood type
No. The Rh Negative blood group is formed by an absence of the Positive factor.
Pregnancy tests are almost always accurate with home tests it is more common to get a false negative then a positive if it says you are pregnant then you are.... With a blood test you will most likely always get the correct reading because your blood changes it increases and it develops a hormone that is only there when pregnant.
B positive or negative or, O positive or negative.
No. Rh negative is a recessive gene. Positive people do not carry it.
they can have a A positive A negative O positive O negative depending on genes of A
