Step #3. The procedure

After registering, you will proceed towards the blood donation station. Once you are comfortable, you will have to roll up the sleeves on both arms. Two needles are required, one for drawing blood and the other for returning.

Needles are inserted in veins on both arms and are attached to a centrifuging machine. You will not feel any pain during the platelet donation. However, while inserting a needle might sting a little bit. 

You can sit back and relax, as the blood from one of your arms will go into the centrifuging machine, separating the blood into its component and collecting the platelets. The centrifuging machine spins the blood at a high rate and separates all the blood components according to their densities.  

This blood spins several times for one donation. And the collected platelets will be in the sterile bag. The rest of the blood components will return to the body through a needle on another arm. This process of platelet donation will take approximately two to three hours.  

The platelet taken in this donation is equal in quantity to the platelet collected from three whole blood donations. Sometimes the platelets donated by one induvial can be used for three patients.  

 

Step #4. After the donation

Once the process ends, the medical staff will remove needles and send the collected platelet bag to the blood bank. You should rest for 15 to 30 minutes after donation and eat snacks. Usually, the people at the blood donation drive or the clinic will provide you with snacks and a water bottle. 

Eating after the donation is as important as eating before donation, which will prevent you from feeling tired or weak or lightheaded. To prevent dehydration, you must drink plenty of water for the next twenty-four hours.
