Types Of Blood Donation

Whether you’ve done it before or are a first-time donor, there are a variety of blood donation options that can meet a variety of medical needs. Donations of whole blood, red blood cells, platelets, and plasma fall under this category.

#1. Whole blood donation

One of the most prevalent types of blood donations is a whole blood donation. As soon as the blood has been drawn, it can be utilized for transfusions. Platelets and plasma, for example, can be extracted and purified. It may take up to an hour or more to donate one’s full blood, yet it is extremely beneficial to those having surgical procedures.

#2. Power red donation

An alternative is the use of a concentrated quantity of red blood cells from your own body, known as a “Power Red Donation.” During the extraction process, a machine separates your blood’s red blood cells from the rest.

#3. Platelet donation

Platelets are a type of blood cell that aids in wound healing by preventing bleeding. When dealing with Dengue fever, they’re especially important.

#4. Plasma donation

Those with blood type AB are the best candidates for donating plasma. When it comes to treating different blood types, the AB plasma might be employed.

What To Do Before, During, And After Donating Blood

If you’re thinking about participating in a blood drive, use the following check list to make sure you’re prepared for the process from start to finish.


Making an appointment or attending a local bloodletting campaign are two options if you desire to donate blood. Rather than having to go to the site and wait for a bloodletting campaign in your region, you can schedule an appointment and save time. It’s also important to keep an eye on your diet. Foods high in iron should be prioritized when trying to meet your daily iron needs. Red meat, chicken, and fish are all good sources of iron. Vegetarians can eat beans, spinach, raisins, or iron-rich cereals to get their daily iron intake. Take care of yourself by getting enough sleep and drinking enough of water. Before donating blood, it is critical to keep your body at ease. Be sure to keep track of how much water you consume as well. Make sure you drink enough of water the day before the donation. Before donating plasma, it’s a good idea to figure out what you’re going to consume.


Activating your RapidPass before donating blood is a smart move. Using the RapidPass app, you may keep tabs on the progress of your blood donation and set up an appointment. Bring a photo ID with you. Regardless of whether this is your first time donating, you will be required to present a donor card. Also, if you have one or two kinds of identification, apply for a driver’s license.

Make a list of the medications you’ve been taking for the past three months. If you have a medical condition that affects your blood quality, you need to tell the medical personnel about it. Draw blood while wearing a t-shirt or sleeveless top that can be easily rolled up. In addition to mp3s or a favorite book, you may also pack a pillow and a blanket to keep you comfortable.

After your donation:

  • At the very least, keep your bandage on for four hours. Do not remove the bandage for more than four hours after you notice any new bleeding.
  • Before you leave, make sure you’ve had something to eat and drink. Drink plenty of fluids over the next three days to make up for the volume you lost when you donated blood. In the first four hours following a donation, it is very crucial to consume a lot of water.
  • Take a 12-hour break from hard lifting and intense activity. The needle site will heal and your body will be able to adjust to the blood loss as a result of this.
  • After donating blood, the skin may appear bruised or discolored. Black, blue, or brownish-green discoloration is caused by the accumulation of blood beneath the skin. There is no need for any kind of treatment. The bruising should go away on its own in a few days.

Special instructions: Call the Donor Services Nurse at (206) 398-5999 if you have questions

  • A cold compress should be applied for 20 minutes, four times a day for the first two days in order to reduce swelling and pain; then a warm compress should be used for 20 minutes, four times a day until the discomfort has subsided.
  • A fall and damage are likely if you don’t take action quickly enough if you suffer dizziness, lightheadedness, or the feeling that you are about to faint. Hold this position for as long as you feel the pain subside. If the symptoms don’t go away, see a doctor.
  • Remove the bandage in 1 hour and rewrap loosely if you had an artery puncture. For at least 24 hours, do not lift anything with your affected arm. A problem with the arterial puncture can be addressed by calling the nurse at the number shown above or by seeking medical assistance.
    • Pupil size differs from eye to eye, with one being larger than the other.
    • a worsening of an existing headache
    • Seizures and convulsions
    • Reduced ability to coordinate
    • vision that is doubled or distorted (since the donation)
    • Vomiting and nausea on a regular basis
    • Unusual conduct, such as excitement or disarray
  • If you notice any redness, oozing, pus, or a fever of 100.5 F or higher at the venipuncture site, please call the number listed below.

What to Expect When You Give Blood

Considering donating blood? Here are some things to keep in mind. Volunteering to donate blood is an easy and safe way to help others. Knowing what to expect before, during, and after your donation will help you get ready.

Blood Donation Benefits

People in the United States require blood every two seconds. You may be able to help someone by donating blood:

  • They are people who have been through a tragedy or an emergency.
  • Those who suffer blood loss as a result of serious surgery
  • Gut-bleeding patients who have had blood loss
  • In cases where a woman’s pregnancy or childbirth goes awry,
  • People who have cancer or severe anemia due to thalassemia or sickle cell disease may benefit from chemotherapy.

Those who regularly donate blood may also get the benefits:

  • Iron levels in the blood are lower than normal. If your iron levels are too high, this is a good thing. When you donate blood, you remove some of your red blood cells, which carry iron throughout your body.
  • Improved levels of cholesterol and triglyceride. People who routinely donate blood and those who do not were both studied in a study that measured total cholesterol, triglyceride levels, HDL (good) cholesterol and LDL (bad). Blood donors had decreased triglyceride, total, and low-density lipoprotein (LDL) cholesterol levels. To my knowledge, I have no idea why this is happening.
  • It’s rewarding to know that you made a difference in someone else’s life, even if it was a complete stranger. Taking part in a blood drive with a group of people may also have advantages.

Before You Donate

Make sure you satisfy all of the standards and prepare appropriately if you plan on donating blood.

Conditions for donating blood. Find a blood bank or drive and schedule an appointment first. For donations, be sure to inquire about any special requirements, including what forms of identification are required.

We require you to be:

  • In most places, you must be 16 or older to donate whole blood (and 17 or older to donate platelets).
  • Weigh a minimum of 110 lbs.
  • I’m in great shape and feel great

The 4 Steps of Blood Donation

There are four steps involved in donating blood:

  1. Registration
  2. Medical history and a brief physical exam
  3. Donation
  4. Refreshments

Despite the fact that the entire process can take up to an hour, the actual donation can be completed in about 8-10 minutes. Your blood is returned to you after a machine removes the platelets and filters them out. It takes longer to do this procedure (2-3 hours).

How Long Are you Supposed to Leave This Bandage On?

Prior to making a donation, you will be interviewed in private by a member of the blood bank staff to learn more about your health and lifestyle. You’ll also be subjected to a “mini-physical,” a brief health checkup. Your pulse, blood pressure, and temperature will be measured by an employee, who will also collect a little sample of blood for testing.

  • Your medical record
  • Travel
  • Medications that you regularly consume
  • (questions are focused on specific behaviors rather than sexual orientation).

Questions are based on AABB (previously known as the American Association of Blood Banks) and FDA-approved standards for blood donor screening.

They’ll do a blood test to determine your blood type and to look for any abnormalities:

  • a parasitic infection known as Babesiosis
  • Antibodies to the CMV virus
  • Infectious hepatitis B
  • Histiocytosis C
  • HIV
  • Donors who have ever been pregnant or have been pregnant since their last blood donation are required to provide antibodies against human leukocyte antigen (HLA).
  • Viral infection of the human T-lymphocyte
  • Syphilis
  • An infection caused by Trypanosoma cruzi.
  • The West Nile Virus
  • Zika is a contagious disease.
  • When you arrive at the hospital, you will be taken to a donor room and placed on a cot.
  • A sterile needle will be inserted into your vein by a phlebotomist (a blood draw employee). A short pinch can be felt in the process, which takes only a few seconds.
  • A pint (or one unit) of blood is what you’ll be donating. It should take no more than 10 minutes to complete. Apheresis, on the other hand, can take up to two hours if you’re donating platelets, red blood cells, or plasma.
  • After that, you’ll elevate your donor arm and apply pressure to it to aid in the clotting of your blood. Your arm will be covered in an adhesive strip at this point.

Side Effects After Donating Blood

Temporarily, you may experience the following side effects, none of which are harmful.

  • Hydration is required. For the first 24 to 48 hours after donating blood, drink more non-alcoholic beverages.
  • It’s time to ease up a bit. Don’t engage in any strenuous physical activity for 24 hours after donating blood.
  • I’m feeling a little dizzy. Once you’re ready to stand up again, take a few minutes to relax on the couch.
  • There should be a small amount of bleeding from the site where the organ was donated. For a few minutes, raise your arm and apply pressure to the area.
  • Use an ice pack on the bruising if you have any.


It is important to know how long to leave the bandage on after blood donation because it protects the needle region from the elements outside our body.
