Can I donate blood to a friend or family member?
You may donate blood for a family member or friend. This type of donation is a
directed or designated donation. It requires the consent of the patient and the
patient's physician. The designated donor must meet the same criteria as a regular donor.
To provide sufficient time for the blood to be tested, the donation must take place at
least five working days in advance of the expected transfusion. If the intended recipient
doesn't need the transfusion, the blood can be made available to other patients.

You may donate you own blood in advance of your own surgical procedure.
This is an autologous or autogenic donation. Special requirements for this type
of donation are:
- You must not have a history of heart disease or stroke
- You must be able to emotionally tolerate the donation process
- Although there is no weight limit, you must be able to tolerate a ten-fifteen percent blood-volume reduction
- The consent of the surgeon is required
- Some medical conditions may require additional medical clearance.
- Up to three units of blood may be donated. Each donation must take
- place at least one week apart. Blood can be collected up to 72 hours before surgery.

blood donations. We are happy to accommodate both large and small groups.
If your organization would like to host a blood drive, here's all you have to do:

We bring all the equipment and supplies, along with juice and cookies, necessary

What is the process for donating blood?
The entire process of donating blood usually takes about thirty minutes. This includes
the pre-screening, the donation, and a brief rest period immediately following the donation.
Before
You should eat a regular meal on the day of your donation. Remember to bring
identification. At the donation site you will be asked to provide basic information
about yourself, such as name, address, and phone number. The Donor Center staff
will check your pulse, blood pressure, temperature, and hemoglobin level. We will
also ask you a few questions about your medical history.
During
The actual process of donating blood takes only 5 to 10 minutes. One unit of blood
(about one pint) will be collected.
After
After the collection process, we provide refreshments and the opportunity to rest.
Your body starts to replenish its blood supply almost immediately. Drink extra fluids
for the first twenty-four hours after donating. You will receive a donor's card with your blood type and total cholesterol level results about three weeks.
What happens to my blood after it is collected?
After being collected at the donor site, blood is taken to the blood bank. There, some
of the blood is used for screening purposes (HIV, HTLV, hepatitis, syphilis). Some is
tested to determine your blood type and to measure your cholesterol level. The rest is
processed and broken down into its component parts.
