Double Red Cell
Each Year, nearly
6,000 units of red blood cells are needed in the NIH Clinical Center
to treat patients undergoing cancer therapy, organ and tissue transplants
and other diseases that require blood transfusions. If you'd like
to donate but can't seem to find the time, now there is a new donation
option at the NIH Department of Transfusion Medicine called Double
Red Cell Apheresis (DRCA). This procedure will let you give two
units of red cells in one visit to the blood bank. While the procedure
itself takes slightly longer, you won't be eligible to donate again
for 4 months.
In addition to saving time spent traveling, parking, and undergoing
medical screening on two different occasions, there are numerous
advantages to Clinical Center patients.
What Is Double
Red Cell Apheresis?
Double red cell apheresis is a procedure that allows a donor to
give two units of red cells at the same time. This is done by a
procedure called "apheresis", which has been used for
many years to separate whole blood into component parts such as
red blood cells, platelets, plasma and white blood cells. To remove
red cells, a needle is placed in your arm and the blood flows into
a sterile, disposable plastic kit installed in a machine designed
specifically for this purpose. As blood enters the machine, the
bowl is spinning at a very high rate of speed. This causes the components
of the blood to separate so that the red blood cells can be siphoned
into a blood bag. Plasma and other parts of the blood are than returned
to you through the same needle. The process is repeated to collect
two units of red blood cells.
Is Double
Red Cell Apheresis (DRCA) Safe?
Absolutely! The machine and the procedure have been evaluated and
approved by the Food and Drug Administration, and all plastics and
needles coming into contact with you are used once and discarded.
At no time during the procedure is the blood being returned to you
detached from the needle in your arm so there is absolutely no risk
of returning the wrong blood to you.
What Are
The Donor Requirements?
Because you will be losing more red blood cells during this procedure
the following criteria is different than whole blood donation.
Men
Minimum weight
- 130 puunds
Minimum height - 5'1"
Women
Minimum weight - 150 puunds
Minimum height - 5'5"
All donors must have a slightly higher red cell count that is validated
by a hemoglobin of 13.3 gm/dl. To assure that you do not become
anemic the interval between DRCA and other donations is 4 months.

How Long
Does The Procedure Take?
The time required to remove two units of reds cells is about 45
minutes. Allow an hour and 15 minutes from start to finish. Because
you'll be with us longer, there will be time to watch TV, read or
just chat with staff and other donors. Every effort will be made
to make the experience relaxing and enjoyable.
