Question 5 of 20 Correct

How long does it take your body to replace the blood lost during a donation?

Correct! Sorry, that’s incorrect.

Blood Donation Quiz
Question 6 of 20 Correct

True or false: If you are anemic, you will not be allowed to donate blood.

Correct! Sorry, that’s incorrect.

The correct answer is: This is true. Anemia can be a sign of low iron. Before you donate blood, your blood will be quickly tested for hematocrit and hemoglobin measurements; this lets the nurses and healthcare providers drawing blood know if you're anemic. If you are, you will not be able to donate.

Blood Donation Quiz

True or false: People who were once anemic can never donate blood.

Correct! Sorry, that’s incorrect.

The correct answer is: This is false. If you're deferred from donating blood because you're anemic, you can--and should--try again. Ask the blood donation organization for information on increasing your iron intake to get it to normal levels.

The correct answer is: This is false. You may donate blood if you were vaccinated for influenza, as long as you are not sick and do not have a fever at the time you wish to donate. For some vaccines, there is a waiting period between inoculation and when you can donate blood. However, once that window has passed, you should be allowed to donate.

Blood Donation Quiz
Question 16 of 20 Correct

How many blood types exist?

Correct! Sorry, that’s incorrect.

The correct answer is: Humans have four major blood types: A, B, AB and O. Blood types are determined by proteins on the blood cell's surface—these are called antigens. There are only two antigens, A and B. If you have type AB blood, then both A and B antigens are present on your red blood cells. If you have type O blood, neither A nor B antigens are on your red blood cells.

Blood Donation Quiz

True or false: Type O blood is called universal blood because anyone can use it.

Correct! Sorry, that’s incorrect.
