    You often can tell when a person is having an asthma attack by the hoarse whistling sound made while exhaling. This sound, known as wheezing, occurs because air becomes trapped in the lungs. Coughing after exercise, crying, or laughing are other signs that an asthma attack could begin.

    If you find a tick embedded in a person’s skin, it must be removed.
    • With a gloved hand, grasp the tick with fine-tipped and pointed tweezers that have a smooth inside surface. Get as close to the skin as possible. Pull slowly, steadily and firmly with no twisting.

    After blood is donated, it is tested in a laboratory to ensure it is safe for transfusions. Tests currently performed (as of July 2010 ) include:
    - Each unit of blood is tested for the following: ABO and Rh blood groups.
    - Unexpected red blood cell antibodies that are a result of prior transfusion,...Read More

    We all need a safe blood supply. We need to make sure it is safe for a donor to donate blood and for a recipient to receive the donated blood. Most people choose to donate because they want to share their healthy blood with someone who needs it. Some potential donors, however, may have been exposed...Read More

    If a donor’s low hemoglobin/hematocrit is due to low iron, he or she can replenish iron levels by eating more high-iron foods or taking supplements. Foods rich in iron include red meat, fish, poultry, and liver. Other good sources are iron fortified cereals, beans, raisins, and prunes. Eating food...Read More

    American Red Cross answered:
    Hematocrit and hemoglobin measurements are blood tests. Hemoglobin enables red cells to transport oxygen and carbon dioxide. The hemoglobin is checked before each donation to 
    ensure that the donor has adequate red blood cell levels to donate blood. Blood donors must have a minimum of 12.5 g/dL...Read More

    Some blood groups are more prominent in certain ethnic groups. For example, about 60 percent of the Latino population is group O. Only about 45 percent of the population of other ethnic groups is group O.  Many African Americans have group O or B blood. Nearly 20 percent of all African Americans...Read More

    Individuals with the blood group O Rh negative are called “universal donors” because their red blood cells can be transfused to people of all blood groups. This is why the Red Cross is constantly recruiting donors whose blood type is O Rh negative. Read More

    Karl Landsteiner will always be honored for his discovery of blood groups. In 1901, he showed that transfusions between individuals of like blood groups (A to A, B to B) do not result in the destruction of blood cells. Transfused red blood cells and the patient’s own red blood cells destroy each other only when...Read More

    American Red Cross answered:
    Most people have an inherited antigen on their red blood cells known as Rh, or D antigen. When the D antigen is present, a person’s blood is designated Rh positive. When D antigen is missing, the blood group is designated Rh negative. In general, Rh negative blood is given to Rh negative patients,...Read More

    American Red Cross answered:
    Nearly all people belong to one of the four major groups in the ABO blood typing system: A, B, AB, and O. Blood groups are determined by antigens found on an individual’s red blood cells. An antigen is a protein or carbohydrate on the cell that triggers an immune response, such as the formation of...Read More

    White blood cells help fight infection. Individuals with a low white blood cell count, who are at risk for serious infections, may benefit from this type of transfusion. Those individuals who are unresponsive to antibiotic therapy may also benefit from this type of transfusion. Read More

    An individual can give up to 24 apheresis platelet donations each year. Apheresis platelet donors have 24 opportunities each year to help save a life. Some apheresis donations can generate 2 or 3 adult-size platelet transfusion doses from one donation! Read More

    American Red Cross answered:
    Apheresis is the process by which platelets and other blood components are collected from a donor. The word “Apheresis” is derived from the Late Latin word “Aphaeresis” meaning “to take away.” This process is accomplished by using a machine called a cell separator. Most commonly, blood is drawn from...Read More
