Preparation
Once you have chosen a day to donate blood, it is a good idea to start eating
iron-rich foods for a few weeks before the day. You can get good amounts of iron from meat, fish, legumes, as well as greens like spinach, kale, beans, and lentils. On the day of your donation,
drink plenty of water and fluids . Wear
loose-fitting clothing with sleeves that can be easily rolled up above the elbow. Don't forget to bring a list of all the medications you take (
prescription and over-the-counter) and your ID.
How often can you donate blood?
If you donate whole blood, you can only donate
once every 4 months . If you donate only platelets or plasma, the period is even shorter.
Blood donation process: 4 simple steps
Although the entire process of donating blood takes about an hour, it actually takes only 8-10 minutes to get your blood drawn. Let's take a look at the steps involved in this process.
| Steps | What is happening? |
|---|
| Step 1: Registration | When you go to the blood donation center, you first need to register by showing your ID. You will be asked to fill out a form with basic information like your name and address. |
| Step 2: Medical examination | Next, a member of the medical staff will talk to you and ask you a few confidential questions about your health and lifestyle. They will also take your blood pressure, pulse, and temperature, and take a drop of blood to check your hemoglobin level. All of this is done for your safety and that of the patient receiving the blood. |
| Step 3: Donation | After the tests, you will be made to lie down on a comfortable bed. A trained phlebotomist will clean your arm and insert a new, sterile needle into your vein. This will only cause a small pain, like being bitten by an ant . Over 8-10 minutes, 1 pint (about 450 milliliters) of blood will be taken. |
| Step 4: Rest and Treat | After donating blood, they will put a plaster on your arm and ask you to rest for 10-15 minutes. In the meantime, you will be given a biscuit and something to drink, such as tea. This rest is very important to help your body recover from the loss of fluids. |
A word about tattoos
If you have a tattoo, it is not a barrier to donating blood. However, it should be done
in a safe place using sterilized equipment . It is usually best to wait 6 months to a year after getting a tattoo before donating blood.
