Blood is the key factor for the sustenance of your body and for your living as well. Studies have revealed that blood is donated on huge level in United States of America and five million people around the nation, as per an estimate are transfused with blood every year.

Unluckily most of the time when the blood supply needs to be high the country has to confront decline of blood supply badly. As mentioned above blood supply needs to be very high for demand itself is very high. It is to be noted that blood coming from only one percent of the united state’s nation would be enough to meet requirements.

Four groups of blood do exist and are named as –A, B, AB and O- these groups have positive and negative forms, which is contribution of Rh factor. O negative form of blood however, is accepted universally and can transfuse with any group of blood. Blood at the instance of its transfusing has a numerous components, which have to transfuse. These components are platelets, red cells, plasma and nutrients along with watery fluids.

Scientists are working on producing an alternative to blood, human blood so that people will not require donating blood for the sake of saving lives. Studies have made it possible to compose a medicine, which to greater extent but very short periods work as efficiently as blood in the circulatory stream of body. Focus is being held over decreasing the blood spillage and wastage at time of surgeries by surgeons.

Women always have observed to donate blood at very rarely and the major reason being the fact that they menstruate and have lesser amounts of red blood cells in their bodies. A thing worth mentioning here is the fact that iron is very critical to those who are interested in blood donation as this nutrient is important for blood formation. So, whether you donate or not it must be kept in mind that you menstruate, therefore you must provide your body with adequate supply of iron to make up for the amounts of blood you have had lost. The level, which is defined by FDA for the blood donation, is 12.5 g/dl, for hemoglobin.

Blood is approved as the top reason, which works as the vector for the infectious disease transmission. So for this reason blood that is donated is sterilized before transfused. FDA owns the responsibility for making supply for blood free of risk. However, studies still are being conducted around the Globe for the sake of discovering ways to prevent poor or infectious supply of blood. One such successful technique is “sterilization” which is also called by specialists as pathogen inactivation. This procedure includes adding certain chemicals for breaking up genetic material of infectious microorganisms in the blood bag.

The future of the transfusion of blood is expected to come out with something as artificial blood. As blood transfusion, donation and maintenance are considered difficult and chronically short for required blood supply.
