World Blood Donor Day

One drop of blood may seem small, but to someone in need, it holds the power of life. Be the reason someone gets to live another day.

Dr Olakunle Oladehin

Blood Donation and Its Importance

“A Life-Saving Act That Impacts Millions”

World Blood Donation Day is a generous tribute to the millions of voluntary, unpaid blood donors who give others a second chance at life. Every 14th of June, the world celebrates these heroes whose generosity saves lives, strengthens communities, and embodies the spirit of solidarity.

We are in a critical situation regarding blood shortages worldwide, especially in Nigeria.

Did you know that Nigeria needs about 1.8 million pints of blood annually, yet only 27% comes from voluntary donors? Around 80,000 women die each year due to complications during childbirth—many of which are attributed to blood loss, with lack of access to blood transfusion being a major contributing factor.


What is Blood?

Blood is a specialized bodily fluid that circulates through the heart, arteries, capillaries, and veins. It is a fluid connective tissue that provides communication between cells in various parts of the body and the external environment. Blood delivers essential substances such as oxygen and nutrients to cells and removes waste products.

It flows through every organ of the body, kept in continuous circulation by the heart, traveling through:

  • Arteries – carrying oxygenated blood from the heart to the body.

  • Veins – returning deoxygenated blood to the heart.


Composition of Blood

  • Red Blood Cells (RBCs) – Transport oxygen using hemoglobin.

  • White Blood Cells (WBCs) – Defend the body against infection.

  • Platelets – Aid in blood clotting.

  • Plasma – The liquid component carrying cells, hormones, nutrients, and waste.


How is Blood Synthesized?

Blood cells are produced in the bone marrow through a process called hematopoiesis:

  • Stem cells differentiate into RBCs, WBCs, and platelets.

  • Regulated by hormones like erythropoietin (for RBC production).


Importance of Blood

  • Transports oxygen and nutrients to tissues.

  • Removes carbon dioxide and waste products.

  • Fights infections through immune cells.

  • Clots at injury sites to prevent bleeding.

  • Regulates body temperature and pH balance.


Blood Groups

Blood groups are inherited, stable characteristics that give rise to the antigen-antibody system. These may be detected early in fetal life and, except for the Lewis and I systems, remain unchanged until death.

Some red blood cells carry proteins (antigens) on their surface that can stimulate an immune response if transferred between incompatible individuals. The presence or absence of these inherited antigens determines a person’s blood group.


Types of Blood Groups

1. Major Blood Group Systems:

  • ABO System:

    • A

    • B

    • AB

    • O

  • Rhesus System:

    • Rhesus positive

    • Rhesus negative

2. Minor Blood Group Systems:

  • Kell's Blood Group

  • Duffy Blood Group

  • Lewis Blood Group


Why Blood Grouping and Rhesus Factor Matter

  • Ensures compatibility in transfusions.

  • Crucial in pregnancy (Rh incompatibility can affect the fetus).


What is Blood Donation?

Blood donation is the voluntary process of giving blood to help patients in need. It is used in transfusions for illnesses, surgeries, trauma, and chronic diseases such as sickle cell anemia.


Types of Blood Donation

  • Whole Blood – Most common; all components collected.

  • Platelet (Apheresis) – For cancer patients, clotting disorders.

  • Plasma Donation – Used in burns, shock, and clotting deficiencies.

  • Double Red Cell – Collects extra red cells; useful for trauma or anemia.


Who Can Donate?

  • Age: 17 to 65 years

  • Weight: At least 50 kg

  • Hemoglobin: ≥12.5 g/dL (females), ≥13 g/dL (males)

  • Must be healthy and free from infections

  • Must not engage in high-risk behaviors


Health Screening Before Donation

  • Medical questionnaire (illnesses, medications, travel)

  • Vital signs: weight, blood pressure, temperature

  • Hemoglobin test (finger prick)

  • Blood group determination

This ensures donor eligibility and recipient safety.


The Blood Donation Process

  1. Registration & Screening

  2. Donation (8–10 minutes, 350–450 mL)

  3. Rest & Refreshments (10–15 minutes)

  4. Post-donation Advice (stay hydrated, avoid heavy lifting)


Importance of Blood Donation

To Recipients:

  • Saves lives in emergencies and surgeries

  • Treats anemia and sickle cell disease

  • Essential during childbirth and cancer treatment

  • One donation can save up to 3 lives

To Donors:

  • Free health screening

  • Stimulates new blood cell production

  • Regulates iron levels

  • Boosts emotional well-being and sense of purpose


Crossmatching Before Transfusion

  • Ensures compatibility between donor and recipient

  • Prevents transfusion reactions

  • Done after ABO and Rh typing


Universal Donor and Recipient

  • Universal Donor: O⁻ (no A, B, or Rh antigens)

  • Universal Recipient: AB⁺ (has all antigens)

Note: Crossmatching is still required for safety.

 

Recipient Can Donate To Can Receive From
O⁻ All groups O⁻
O⁺ O⁺, A⁺, B⁺, AB⁺ O⁻, O⁺
A⁻ A⁻, A⁺, AB⁻, AB⁺ A⁻, O⁻
A⁺ A⁺, AB⁺ A⁺, A⁻, O⁺, O⁻
B⁻ B⁻, B⁺, AB⁻, AB⁺ B⁻, O⁻
B⁺ B⁺, AB⁺ B⁺, B⁻, O⁺, O⁻
AB⁻ AB⁻, AB⁺ AB⁻, A⁻, B⁻, O⁻
AB⁺ AB⁺ All types

 

Donation Safety

  • Sterile, single-use needles

  • No risk of infection

  • Plasma replaced in 24 hours

  • Red cells restored in 4–6 weeks


Who Needs Blood the Most?

  • Accident and trauma victims

  • Sickle cell or thalassemia patients

  • Pregnant women with complications

  • Cancer and surgical patients

  • Premature babies needing transfusion


Common Misconceptions

  • Myth: It’s painful
    Fact: Only a brief prick

  • Myth: Causes weakness
    Fact: Body replenishes fast

  • Myth: Risk of infection
    Fact: Sterile tools are used


How Often Can You Donate?

(Based on Nigeria – National Health Policy Guidelines)

  • Whole Blood: Every 12–16 weeks

  • Platelets: Every 2–4 weeks

  • Plasma: Every 2–4 weeks

Tips: Stay hydrated and well-rested


Call to Action

  • Be a life-saver. Donate blood.

  • Encourage friends and family.

  • Join or organize community blood drives.

  • One unit = up to 3 lives saved

Powerful Herbal treatment is 100% guarantee for HSV cure, the reason why most people are finding it difficult to cure HSV 1 or 2 is because they believe on medical report, drugs and medical treatments which is not helpful to cure HSV and hasn't proved any sign of helping. Natural roots/herbs are the best remedy which can easily eradicate herpes forever. I never believed it until I was helped and cured of my 16 months genital herpes with natural herbal medicines from Dr Sikies. Where other medical prescribed drugs and treatments failed, Dr Sikies natural herbs helped saved me from Genital herpes permanently and I’m so grateful for this.

Thanks to Dr. keneddy I was cured of herpes. I had been suffering from herpes for seven years before I met Dr. Keneddy who used herbs to heal me. I am living proof that Dr. Keneddy can help others suffering from herpes or any other diseases. I saw Dr.Keneddy recommendations online and contacted him. He prepared herbal medicine and sent it to me. I followed his instructions and took the medicine for 14 days. The results returned negative when I went to the hospital for a test. It was the happiest day of my life to find out that I was cured of herpes. If you also suffering from the same virus or another disease, you can contact him via email [email protected] or WhatApp him on +2347041979530

I have been living with Oral herpes for over 4 years now and it has been a big problem for me. I have been looking for a solution because I can't leave with it, One day I came across a woman's testimony on a forum saying she got cured of her Herpes with the help of Dr Akhimien an herbal doctor from Africa with herbal medicine. At first I did not believe because I was not sure herbs can really take this virus away, but I have no choice than to give it a try and contacted him with his emails, I explain my problems,.. then he told me not to worry that he will prepare the a cure with herbal mixture and send it to me, I got the medicine after 4 days delivery and I use as instructed. After 21 days when the herb was almost finished, I went to a medical doctor, I did a test and discovered that the virus was gone, and my test results were HSV 1%2 negative, I was so surprised and happy! Then I wrote to Dr Akhimien and thanked him for getting me cured from herpes. I advise you to contact this great herbal doctor Akhimien as he has cures for different kinds of diseases. I decided to share this testimony to let others who also suffer from herpes know about this and give hope to others, you can reach him via Email [email protected] also his Website https://drakhiniemodion.wixsite.com/drakhimien or WhatsApp number +2349133157031

I was diagnosed with Herpes four years ago. For over two years, I relied on prescribed medications and treatments, but unfortunately, my condition continued to worsen. The flare-ups became more frequent, the discomfort increased, and even simple daily tasks became difficult to manage.Last year, out of desperation and hope, I decided to try a herbal treatment program from NaturePath Herbal Clinic. Honestly, I was skeptical at first, but within a few months of starting the program, I felt some changes. My discomfort eased, my energy levels improved, and I felt I had more control over my daily life again.It’s been a meaningful experience for me, and I feel more like myself than I have in years. This is simply my personal story. You can visit their website at www.naturepathherbalclinic.com whatsapp +27604189106

My partner left me and my kids due to certain challenges. Life took a downturn from that point, I felt an unbearable emotional pain that got me hooked up to drugs to help with the pain, my life took a different dimension when I had an encounter with Dr Osazu love spell home he was able to bring a level ground between me and my estranged husband and I have reunited with my kids. My home is back to what it used to be, thank you Dr Osazu and here is his email. [email protected]

I have been suffering from a deadly disease (Hsv) for the past 2 years now, I had spent a lot of money going from one places to another, from churches to churches, hospitals have been my home every day residence. Constant checks up have been my hobby not until this faithful day, I was searching through the internet, I saw a testimony on how Dr Jude helped someone in curing his (Hsv) herpes disease, quickly I copied his email which is [email protected] just to give him a test I spoke to him, he asked me to do some certain things which I did, he told me that he is going to provide the herbal cure to me, which he did, then he asked me to go for medical checkup after some days after using the herbal cure, behold I was free from the deadly disease, he only asked me to post the testimony through the whole world, faithfully am doing it now, please brothers and sisters, he is great, I owe him in return. if you are having a similar problem just email him on [email protected] Or WhatsApp him via +2347058053587
