What Happens to Donated Blood?

Step 1: The Donation

  • Donor registers
  • Health history and mini physical are completed
  • About 1 pint of blood and several small test tubes are collected from each donor
  • The bag, test tubes and the donor record are labeled with an identical bar code label to keep track of the donation
  • The donation is stored in iced coolers until it is transported to a Red Cross center
Step1:TheDonation

Step 2: Processing

  • Donated blood is scanned into a computer database
  • Most blood is spun in centrifuges to separate the transfusable components – red cells, platelets, and plasma
  • The primary components like plasma, can be further manufactured into components such as cryoprecipitate
  • Red cells are then leuko-reduced
  • Single donor platelets are leukoreduced and bacterially tested.
  • Test tubes are sent for testing.
Step 2: Processing

Step 3: Testing

  • Steps 2 and 3 take place in parallel
  • The test tubes are received in one of five Red Cross National Testing Laboratories
  • A dozen tests are performed on each unit of donated blood – to establish the blood type and test for infectious diseases
  • Test results are transferred electronically to the manufacturing facility within 24 hours
  • If a test result is positive, the unit is discarded and the donor is notified. Test results are confidential and are only shared with the donor, except as may be required by law
Step 3: Testing Blood

Step 4: Storage

ff
  • When test results are received, units suitable for transfusion are labeled and stored
  • Red Cells are stored in refrigerators at 6ºC for up to 42 days
  • Platelets are stored at room temperature in agitators for up to five days
  • Plasma and cryo are frozen and stored in freezers for up to one year

Step 5: Distribution

Blood Distribution Ambulance
  • Blood is available to be shipped to hospitals 24 hours a day, 7 days a week.

  • Get a good night’s sleep.
  • Drink an extra 16 oz. of water and fluids before the donation.
  • Eat a healthy meal before your donation. Avoid fatty foods, such as hamburgers, fries or ice cream before donating. Tests for infections done on all donated blood can be affected by fats that appear in your blood for several hours after eating fatty foods.

Why Donate Blood?

Donating Blood Saves Lives

Consider the individuals in the hospital needing a blood transfusion. A gunshot or accident victim. Any person needing an ample supply of blood while in surgery. These people need us, and what they ask for is very little. Just imagine what a few pints of blood can do and how many lives it can save.

Donating Blood Increases Your Own Awareness of Cholesterol Levels

One of the added benefits of donating blood is having access to cholesterol levels. Results are readily available to you online so you can gage what you need to change in your diet, or you may just want to maintain healthy levels.

The Health Benefits from Donating Blood

Donating blood has many health benefits. Not only will you help someone in need of blood, but you will also help optimize your health and wellness. Here are the top three health benefits from donating blood.

1. Protect Your Heart by Reducing Oxidative Stress

Iron in your blood can oxidize resulting in damage to your cells and tissues. The increase in oxidative stress is most dangerous to your cardiovascular system.

According to a new study published by the American Medical Association, giving blood every six months led to fewer heart attacks and strokes in test participants ages 43 to 61.

Excessive iron is thought to contribute to heart disease, especially at its early stages. Donating blood on a regular basis reduces the iron stores in the body and this study supports the theory that reducing iron appears to preserve cardiovascular health.

A second study of 2,682 men in Finland, reported in the American Journal of Epidemiology, found that men who donated blood at least once a year had an 88 percent lower risk of heart attacks than non-donors.

This same group of researchers published a follow-up study and found that men who donated blood were less likely than non-donors to show any signs of cardiovascular disease.1

2. Protect Against Developing Cancer

Give blood to help lower your risk of cancer. According to the Miller-Keystone Blood Center, consistent blood donation is associated with lowered risks for cancers including liver, lung, colon, stomach and throat cancers.2

Risk levels dropped in correlation with how often participants donated blood. The association between lower cancer risk and donating blood might also stem from reducing oxidative stress. Free radical compounds can damage your DNA. Damaged genetic material is the hallmark of all cancers.

3. Free Blood Analysis

After donating, your blood will be tested for syphilis, HIV (the virus that causes AIDS), hepatitis and other factors. The center will notify you if tests show you may be unhealthy. Your blood will not be used if it could make someone sick.
