Before you can donate and save a life, we need to check if you’re able to give blood based on eligibility criteria from the Food and Drug Administration (FDA). The FDA’s guidelines are followed by all blood centers in the nation and your eligibility is determined by your medications, travel, health conditions, and lifestyle.
To donate blood or platelets, you must:
Some medications can prevent you from donating temporarily or permanently. If you’ve been prescribed medication, please review this list to determine if you’re eligible to donate blood.
The FDA recently made changes to several guidelines during the COVID-19 pandemic, which may offer additional opportunities for military members and others to give blood. A complete list of the guideline changes is included here.
Still have questions? Call our Donor Eligibility department at 210-731-5590, extension 2243, from 8:30 a.m.-5 p.m., Monday-Friday. You can also email us here.
When you arrive to give blood, you will be asked to show a picture ID. If you didn’t complete your health history questionnaire online through Donor Doc Advance, you will complete a questionnaire on site.
If you’re able to donate blood, you will have a mini-physical where vital signs will be checked, such as pulse, temperature, blood pressure and iron levels.
If you pass the screening, a donor care specialist will guide you to a donor bed. They will swab your arm inside the elbow and insert a sterile needle into a vein. About a pint of blood is drawn (for a whole blood donation) and a bandage is put on your arm.
After your donation, spend 10-15 minutes enjoying a snack and drink. Don’t forget to schedule your next appointment.

STBTC needs to collect an adequate blood supply for more than 100 hospitals in 40 South Texas counties. We depend on volunteer blood donors to make this happen. Also, blood is perishable and there is no substitute.
You receive a mini-physical (pulse, temperature and iron check), earn donor points and redeem them for a FREE gift card of your choice on our rewards store and the satisfaction that comes from saving lives.
The FDA requires that all blood centers ask about your medical history every time you donate to ensure the safety of the blood supply. You have to wait a certain amount of time between donations. A lot can happen in that time. The questions serve as a layer of protection for patients who receive blood.
Refrigerated red blood cells can be stored for up to 42 days. Plasma is frozen and stored for up to one year. Platelets can be stored for only five days.
Blood is used for many different patients including: cancer patients, open-heart surgery patients, diabetics, recipients of organ or tissue transplants, trauma victims and more.
After resting for five to ten minutes and enjoying refreshments to replenish your fluids, you should feel just fine and ready to continue your daily activities. You should refrain from heavy lifting or extreme physical exertion for 24 hours and you’ll feel great knowing you have helped save three lives.
Yes. All supplies used to collect blood are new, completely sterile and used only once. There is no risk of disease transmission to a donor.
Comfort levels vary from person to person but most first-time donors wonder why they waited so long! You will feel a slight pinch and it’s all over before you know it!
The qualifications to be a blood donor are simple. You must be in good general health, at least 17 years of age (or 16 with parental consent form) and weigh at least 110 lbs (or 120 lbs if 16 years old).
If you are a synthetic marijuana user, please do not donate. Read more here for more information.
If you have diabetes, you can give blood as long as it is under control with medication and/or lifestyle.
Was your life saved by the generous gift of blood, marrow, tissue or cord blood? Or are you a donor who’d like to share why you chose to save a life?
For more than 45 years, the nonprofit South Texas Blood & Tissue Center has focused on a critical purpose: to save and improve lives.
Inspired by a group of physicians, our organization was formed to provide blood to the South Texas region – ensuring a safe and adequate blood supply through proper testing, storage and distribution to hospitals. This essential service allows front-line workers to focus on the direct care of patients, with confidence that this lifesaving resource will be there when it’s needed most.
But we didn’t stop there. Over the years, we’ve evolved as the needs of our patients and hospitals have changed, driven to save lives in as many ways as possible.
We couldn’t do this without donors like you. We understand that the gift of donation is a personal, powerful choice that has the potential to touch a life. Today, we offer many ways to make a difference that include:
Our team has also expanded its programs, partnering with leaders within the healthcare industry to develop a wide range of therapies. We’ve recently developed programs to collect and distribute COVID-19 convalescent plasma, as well as improve trauma care.
