  • A newborn baby has about one cup of blood in his or her body.
  • White blood cells are the body's primary defense against infection.
  • Granulocytes, a type of white blood cell, roll along blood vessel walls to search and destroy bacteria.
  • Red blood cells carry oxygen to the body's organs and tissues.
  • There are about one billion red blood cells in two to three drops of blood.
  • Red blood cells live about 120 days in the circulatory system.
  • Blood platelets help clotting and give those with leukemia and other cancers a chance to live.
Facts about blood needs
  • Every year our nation requires about 4 Crore units of blood, out of which only a mear 40 Lakh units of blood are available
  • Every two seconds someone needs blood.
  • More than 38,000 blood donations are needed every day.
  • A total of 30 million blood components are transfused each year.
  • The average red blood cell transfusion is approximately 3 points.
  • The blood type most often requested by hospitals is Type O.
  • Sickle cell patients can require frequent blood transfusions throughout their lives.
  • More than 1 million new people are diagnosed with cancer each year.
  • Many of them will need blood, sometimes daily, during their chemotherapy treatment.
  • A single car accident victim can require as many as 100 units of blood Facts about the blood supply
  • Blood cannot be manufactured – it can only come from generous donors.
  • Type O-negative blood (red cells) can be transfused to patients of all blood types. It is always in great demand and often in short supply.
  • Type AB-positive plasma can be transfused to patients of all other blood types. AB plasma is also usually in short supply.
Facts about the blood donation process
  • Donating blood is a safe process. A sterile needle is used only once for each donor and then discarded.
  • Blood donation is a simple four-step process: registration, medical history and mini-physical, donation and refreshments.
  • Every blood donor is given a mini-physical, checking the donor's temperature, blood pressure, pulse and hemoglobin to ensure it is safe for the donor to give blood.
  • The actual blood donation typically takes less than 10-12 minutes. The entire process, from the time you arrive to the time you leave, takes about an hour and 15 min.
  • The average adult has about 10 units of blood in his body. Roughly 1 unit is given during a donation.
  • A healthy donor may donate red blood cells every 56 days, or double red cells every 112 days.
  • A healthy donor may donate platelets as few as 7 days apart, but a maximum of 24 times a year.
  • All donated blood is tested for HIV, hepatitis B and C, syphilis and other infectious diseases before it can be transfused to patients.
Facts about blood and its components
  • Blood makes up about 7 percent of your body's weight.
  • There are four types of transfusable products that can be derived from blood: red cells, platelets, plasma and cryoprecipitate. Typically, two or three of these are produced from a unit of donated whole blood – hence each donation can help save up to three lives.
  • Donors can give either whole blood or specific blood components only. The process of donating specific blood components – red cells, plasma or platelets – is called apheresis.
  • One transfusion dose of platelets can be obtained through one apheresis donation of platelets or by combining the platelets derived from five whole blood donations.
  • Donated platelets must be used within five days of collection.
  • Healthy bone marrow makes a constant supply of red cells, plasma and platelets. The body will replenish the elements given during a blood donation – some in a matter of hours and others in a matter of weeks.
Facts about donors
  • The number one reason donors say they give blood is because they "want to help others."
  • Two most common reasons cited by people who don't give blood are: "Never thought about it" and "I don't like needles."
  • If you began donating blood at age 18 and donated every 90 days until you reached 60
  • Only 7 percent of people in India have O-negative blood type. O-negative blood type donors are ‘’universal donors’’ as their blood can be given to people of all blood types.
  • Type O-negative blood is needed in emergencies before the patient's blood type is known and with newborns who need blood.
  • 0.4 percent of people have AB-blood type. AB+ type blood donors are ‘’universal donors of plasma’’, which is often used in emergencies, for newborns and for patients requiring massive transfusions.
