is the part of life that is given
to those who need it by those who
have the resource to satisfy the
need. The love of fellow human and
a desire to share something of one
is what singles out a blood donor
from the others. Emergencies occur
every minute. For each patient requiring
blood, it is an emergency and the
patients could have set back if
blood is not available.
There are four
main blood types: A, B,
AB and O. The gift
of blood is the gift
of life. There is no substitute
for human blood.
Every year our
nation requires about 4
Crore units of blood, out
of which only a meager 40
Lakh units of blood are
One blood donation
can save as many as three lives.
One unit of blood can be separated
into several components, including
red blood cells, plasma and platelets.
Red blood cells carry oxygen to
the body's organs and tissue. Plasma
is a pale yellow mixture of water,
salts and proteins, including solvable
clotting factors; plasma is 90 percent
water and constitutes 55 percent
of blood volume. Platelets are small
blood cells that initiate blood
clotting, controlling bleeding.
Every three seconds,
someone needs blood. Blood fights
against infection and helps heal
wounds, keeping you healthy. Anemic
patients need blood transfusions
to increase their iron levels. Cancer,
transplant and trauma patients and
patients undergoing open-heart surgery
require platelet transfusions to
survive. People who have been in
car accidents and suffered massive
blood loss can need transfusions
of 50 units or more of red blood
The average bone marrow transplant
requires 120 units of platelets
and about 20 units of red blood
cells. Severe burn victims can need
20 units of platelets during their
treatment. Children being treated
for cancer, premature infants, and
children having heart surgery need
blood and platelets from donors
of all types.
is a special kind of blood donation
that allows a donor to give specific
blood components, such as platelets.
Platelets must be used within five
days of collection; hence blood
donations are especially needed
around 3-day weekends. Red blood
cells must be used within 42 days.
Plasma can be frozen and used for
up to a year.
Blood makes up
about 7 percent of your body's weight,
and the average adult has 10 pints
of blood in his or her body. Since
a pint is pound, you lose a pound
every time you donate blood.

belonging to the O- blood
group are called universal blood
donors. The red blood cells
of a universal blood donor may be
transfused to anyone regardless
of their blood type.
· The plasma of those belonging
to the AB blood group may be transfused
to anyone regardless of blood type.
