The number of people who come forward to donate blood are just too small as compared to the overall demand for blood to be used for the medical treatment of patients. The need for donations have always remained high. The shelf life of blood being relatively low, continuous replenishment of stocks is necessary for the blood banks. Platelets can be stored for only a week and the maximum storage time for red blood cells is only 35 days. For meeting the requirement of certain types of blood, donations from a wide variety of blood donors is necessary. If you are already a voluntary blood donor, start motivating others to join the campaign of blood donation. Save lives and light up the lives of others.
Pre donation checks

Checking for anemia
Next, a droplet of blood is taken from your finger tip to ascertain the amount of haemoglobin in it. The substance present in red blood cells is the haemoglobin and it helps oxygen to be carried around the body. Lower haemoglobin in the red blood cells or less number of red blood cells are indicators of Anaemia. If you have low haemoglobin level, donating blood will further reduce it and aggravate the problem for you. So, even if your blood is found to be suitable otherwise, you could be disqualified from donating blood, being anaemic.
