- How much blood is taken?
- A unit (about one pint) of blood is drawn. This procedure takes about five to 10 minutes. The average person has between 8 and 12 pints of blood in their body. It takes about one month to replace the blood that is donated.
- How often can I donate?
Giving whole blood requires a waiting period of 56 days between donations. If you donate plasma (your red cells are returned to you), you may donate every 28 days. If you donate platelets (your red cells and most of your plasma are returned to you), you may donate every seven days, with a maximum of 24 times per year.
If you are type A blood you would make a terrific platelet donor! It takes a little more time, but it helps people who are quite ill.
Remember, type AB blood makes good plasma donors, and type O and B blood make good red cell or whole blood donors.
If you donate double red cells (most of your plasma is returned to you), you must wait 112 days before your next donation. Double red cell donors must meet certain weight, height and hemoglobin (iron) requirements.
- How often can I give whole blood?
- You can donate whole blood every 56 days; however, all we ask is for individuals to Commit for Life and donate once every quarter. It takes three easy steps to Commit for Life:
- Donate at least once every quarter;
- Allow The Blood Center to contact you; and
- Spread the word, encouraging family and friends to donate
- Can you explain the blood donation process?
- Donating blood takes less than one hour from the time you arrive until you are ready to leave. First you complete a registration form with basic information such as your name, address and birthdate. You also will present identification that shows your name and your photo or signature. Then, one of our medical professionals will check your blood pressure, temperature and hemoglobin level (iron); take a look at your arm to make sure it is clear of any signs of infection; and ask you confidential questions about your health to ensure that you are eligible to donate blood that day. The actual whole blood donation takes between five and 10 minutes. Afterwards, you will be given juice and light snacks to replenish lost fluids during donation.
- How long does it take?
- The entire donation process, from registration to post-donation refreshments, takes just under one hour. The actual donation takes 5 to 10 minutes. We encourage donors to make and honor appointments to avoid long delays. To make a donation, visit Where to Donate or Digital Donor.
- How will I feel after I donate?
- Most people feel fine after donating blood. A unit of blood (500 ml) is less than a pint, and the average adult body contains 10 to 12 pints of blood. Your body makes new blood constantly, and the fluid you give will be replaced within hours. Eating a full meal within four hours before donating will help you feel strong after donating. Drinking water and juices before and after donating also helps your body replenish lost fluids. You should avoid alcohol before and after donating. Strenuous activity should be avoided for 12 hours after donating. If you have a hazardous or strenuous job, you should donate at the end of your work shift. Smokers should refrain from smoking 30 minutes after donating.
- How long will it take to replenish the pint of blood I donate?
- Your body will replace the blood volume (plasma) within 48 hours. It will take four to eight weeks for your body to completely replace the red blood cells you donated. The average adult has eight to 12 pints of blood. You will not notice any physical changes related to the pint you donated.
- What happens to my blood after I donate?
- Your blood will be tested for various infectious agents, including HIV and hepatitis. It will then be processed into components (red cells, platelets, plasma). After processing, red cells can be stored for 42 days, platelets can be stored for five days and plasma can be frozen for one year. Your single unit of blood can help save the lives of up to three separate patients.
- What benefits are available for individuals who donate blood?
- In addition to helping save up to three lives, blood donors receive many benefits For example; all donors receive a mini-physical exam at the time of their donation. This includes the determination of hemoglobin levels (as sign of anemia), blood pressure, temperature, blood type and various blood screening tests. Additionally, individuals who Commit for Life receive points that can be redeemed for great items in the Commit for Life store, invitations to specialty recognition events and more.
- What do I need to know about the Advanced Wellness Check?
- To obtain accurate lipid-profile results, the blood sample should be taken when the individual has been fasting (no food or drink for 12 hours). Therefore, you will not be able to have a sample drawn for this testing at the same time you donate blood. Samples will be drawn at one of our fixed-site facilities. To schedule your annual Advanced Wellness Check, please call (713) 791-6260 or 1 (800) 791-1666.
- What is considered normal and high blood pressure?
- Blood pressure levels available here.
- How can I reach the the next Commit for Life level?
- Commit for Life donors reach a new membership level with every donation. If you donated twice last year to become a bronze-level donor, donate three times this year to be a silver-level donor or four times to become a gold-level donor! Every donation helps save up to three lives!
- How do I get to the Commit for Life online store?
To redeem points, you will access the store by logging on Digital Donor. You'll need your Donor-ID number to log onto Digital Donor. You can find that number on your donor card or by calling (713) 791-6260.

- Is it safe to receive blood?
- Yes. The blood supply is now safer than ever. Every potential donor undergoes a thorough screening by a trained professional, and every unit undergoes many tests to ensure safety.
- Which patients use what components?
- Every whole blooddonation can help save up to three lives. This is accomplished because the donation is separated into three separate components:
- Red blood cells can be used to help accident victims, surgical patients and people with anemia.
- Platelets can be used to treat leukemia and cancer patients.
- Plasma is effective in treating patients suffering from burns or shock.

Variant Creutzfeldt-Jakob Disease (vCJD) is a fatal degenerative disease affecting the nervous system that is found almost exclusively in the United Kingdom. It has been linked to another disease often referred to as "Mad Cow Disease." The risk of vCJD is unknown, however, only two cases associated with blood transfusion have been detected. Neither was in the United States. Learn more about vCJD.
Current FDA guidelines prevent you from donating blood if you have spent an extended amount of time in the United Kingdom and Europe. The guidelines are:
- if you traveled or lived in the United Kingdom for a total time of three months or more between 1980 and 1996, you are not eligible to donate blood.
- If you have traveled or lived for a total of five years or more in any other European (however, does not include Russia) country since 1980 to the present, you are not eligible to donate.
- If your were associated with the military and stationed on a military base in Europe for more than six months between 1980 and 1990 (Belgium, Germany, Netherlands & the United Kingdom) or for six months or more between 1980 and 1996 (Greece, Italy, Portugal, Spain & Turkey), you are not eligible to donate blood.

Neither of these vaccines affects donor eligibility. Because there is no deferral period, you may donate blood the same day you receive the seasonal flu vaccine or H1N1 flu vaccine. As always, donors must be in general good health without any cold or flu symptoms.
Autologous and Directed Donations Questions
- Can I donate blood for myself?
- Yes. It is called an autologous donation. Autologous (au-tol-o-gous) blood transfusion is a procedure in which you are transfused with blood that you have donated only for yourself. This type of donation only can be conducted with written permission from your physician. A written order must be faxed to the Autologous and Directed Program of The Blood Center. Your physician can obtain a "Request for Autologous/Directed Donation" form by calling (713) 791-6608 Monday through Friday from 8 a.m. to 5 p.m., or you may download it here, and take to your physician to complete.
- Will I be charged for directed donations if the donors are not compatible?
- If your donors are not compatible there is no charge. But if we are not provided with the patient's blood type when we draw the unit, then we send every donation to the hospital. After the hospital cross-match is done and it is concluded that the donation is incompatible, then there is only the direct fee of $26.
- Why does my blood expire sooner if I am a blood relative?
- If you are a blood relative, your donation will have to be irradiated to avoid graft vs. host disease (donor's cells attack the patient's tissues). In this instance, the 42-day expiration for red blood cells is then reduced to 28 days.
- Why do I have to pay for my own blood?
- The charges assessed with an autologous donation are to recover costs for testing, processing and service fees.
- Do you ship blood internationally?
- No, clearing the blood units through customs is very difficult. We cannot regulate the blood temperature once it leaves The Blood Center.
- Why do I need doctor's orders before donating autologous or directed units?
- We must have a doctor's request in order to make sure we have all the proper information for the patient (what components are needed, social security numbers, date of birth, doctor's name, fax and phone number, name of hospital, etc.). We also make sure the doctor has authorized the patient to give an autologous donation.
- If I'm having surgery out of town, can I donate here and have it shipped? And at what cost?
- Yes, you may donate with a physician's request at any of our local Neighborhood Donor Centers. But all units must be prepaid before any donations are made. This fee varies depending on how many units your physician wants. It includes testing and processing fees, autologous and/or directed fees, and shipping and handling.
- Why can't I know the names of or other information about my direct donors?
- All information is kept strictly confidential in accordance to HIPAA (a set of rules designed to protect patients and their health information).
- What is HBsAG?
- HBsAg stands for hepatitis B Surface Antigen. This test identifies hepatitis B antigens and antibodies, which help determine if a person is infected with hepatitis B virus (HBV).
- If I don't use my autologous donation, why can't it be released for someone else?
- Autologous donations are not drawn under the same criteria as a regular whole blood unit. Some physicians will allow autologous donors to donate who otherwise would not qualify to donate for the general public. Therefore, these units cannot be released for someone else to use.
