  • Fibrogen is the key protein

    Fibrogen is the key protein
    William Hewson, a British anatomist researched about blood coagulation and found out that fibrogen is the key protein in the clotting process.
  • Human to Human

    Philip Syng was the first person to perform a human to human blood transfusion; however, his work is not published.
  • Recorded the first human to human blood transfusion

    James Blundell, a physiologist performs a human to human blood transfusion and it was recorded for the first time.
  • Platelets

    Sir William Osler is the person that observes the small cell fragments from the bone marrow that makes up bulk of the colts, and it is called platelets.
  • 3 main groups of blood

    Karl Landsteiner, an Austrian physcian releases a detailed paper on his discovery of the three main bllod groups which are A,B, and C; however, he later changes it to O.
  • Blood clotting

    Blood clotting
    Researchers found a way to prevent blood clotting and it is by adding sodium citrate to blood.
  • Preventing coagulation

    At the New Yorker's Mount Sinai Hospital, Dr. Richard Lewishn creates a concentration of sodium citrate that can be mixed with donor blood to prevent coagulation.
  • Blood depot

    Dr. Oswald Robertson collect and store type O blood with citrate glucose solution to create the first blood depot that can be stored and delivered during the WWI War.
  • Blood service at home

    At home in London, Percy Lan Oliver operates a blood donor service. He recuits volunteers and before they donate blood, everyone are screened for diseases and tested for blood type.
  • 1st blood transfusion at the hospital

    The first to establish a system of facilities to collect and store blood for the transfusions at the hosiptials are the Soviets.
  • Storing citrated blood

    Anesthesiologists at the Mayo Clinic in Rochester, MN are the first to begin storing citrated blood for transfusion with a hospital setting in the US.
  • Separate and perserve blood plasma

    Drs. Karl Landsteiner and Alexander Wiener found the Rh blood group, through experiments with the RBC of Rhessus monkeys. In addition, during the WW2 Dr. Chareles Drew uses a technique to separate and perserve blood plasma.
  • Blood banks

    Blood banks
    The American Assiociation of Blood Banks is a natinal network of blood banks that was formed by serveral blood banks joined together.
  • Plastic bags for blood

    Plastic bags for blood
    Instead of storing blood in a fragile glass container, Dr. Carl W. Walter, develops a plastic bag for the collection of blood.
  • Structure of hemoglobin

    Structure of hemoglobin
    Dr. Max Perutz uses the x-rays and found out the structure of hemoglobin, the protein with RBC that carries oxygen.
  • A way to stop bleeding

    Dr. Judith Pool discovered that slowly thawed frozen plasma yields deposits hign in factor VII and the deposit is called Cryo. Cryo can be given to hemophiliacs to stop bleeding and this means a person doesn't have to travel to the hospital to be treated.
  • FDA tests

    The FDA tests the blood and found out that a substance on the surface of the hepatitis B virus that starts the production of antibodies. Soon, they dicovered that many blood donors were infected; therefore, the tests is a mandatory by FDA.
  • Gay-related Immunodeficiency Disease

    Dr. Bruce Evatt found out that they Gay- related Immunodeficiency Disease may be blood borne, which he shows his theory to the US Public Health Service.
  • AIDS

    Dr. Robert Gallo discovered the virus that causes AIDS which he calls the human T-cell lymphotrophic virus.
  • HIV antibodies

    When many Americans got AIDS from blood transfusion the first screening shows that the HIV antibodies were present.
  • 1987-2002 Donors were infected

    Due to many infected donor donating blood, people are required to take several screen tests to detect if they have the virus HCV or HIV.

    Illustrations on tomb 2500 BCE
    A way to treat patients is by the method bleeding. People found out due to the illustrated tomb in Memphis, Egypt.
