Blood OTG

Blood OTG takes a request from a user and informs others whose blood group matches with the requested blood group. It sends notifications to them instantly. The seeker is also notified when someone accepts the request. Then they can contact with each other. Blood OTG also ensures that a single person can request for his blood group by just two clicks. However, he can edit some of his information if he wants to.

Users can request for blood with multiple (up to 3) photos with descriptions of each.

Blood OTG doesn't charge for any donation. Neither the blood seeker nor the blood donor is charged.

In emergency situations this app lets you request for blood without writing anything. It saves the time and energy that you need to post on a social media. Blood OTG instantly sends notifications to the ones whose blood group matches with the required group.

Safe blood saves lives and improves health. Blood transfusion is needed for:

women with complications of pregnancy, such as ectopic pregnancies and haemorrhage before, during or after childbirth;
children with severe anemia often resulting from malaria or malnutrition;
people with severe trauma following accidents; and
many surgical and cancer patients.

It is also needed for regular transfusions for people with conditions such as thalassaemia and sickle cell disease and is used to make products such as clotting factors for people with haemophilia.

There is a constant need for regular blood supply because blood can be stored for only a limited time before use. Regular blood donations by a sufficient number of healthy people is needed to ensure that safe blood will be available whenever and wherever it is needed.

Blood is the most precious gift that anyone can give to another person — the gift of life. A decision to donate your blood can save a life, or even several if your blood is separated into its components — red cells, platelets and plasma — which can be used individually for patients with specific conditions.

There are two main methods of obtaining blood from a donor. The most frequent is to simply take the blood from a vein as whole blood. This blood is typically separated into parts, usually red blood cells and plasma, since most recipients need only a specific component for transfusions. A typical donation is 450 milliliters (or approximately one U.S. pint) of whole blood, though 500 milliliter donations are also common. Historically, blood donors in India would donate only 250 or 350 milliliter and donors in the People's Republic of China would donate only 200 milliliters, though larger 300 and 400 milliliter donations have become more common.

The other method is to draw blood from the donor, separate it using a centrifuge or a filter, store the desired part, and return the rest to the donor. This process is called apheresis, and it is often done with a machine specifically designed for this purpose. This process is especially common for plasma and platelets.
