Global Variations in Blood Collection: What Explains the Differences?
Maxime Dely, Sales and Application Specialist in Therapeutic Apheresis and Cell Therapy, has shared a post on LinkedIn:
”Blood Donation: Why do collection volumes vary by country?
You might think that donating blood is the same experience everywhere.
However, the volume collected depends… on the country! And that’s no coincidence.
In France, the standard volume is 475mL per donation. This is very close to what’s practiced in Germany, Canada, or the United States, where 500mL is collected. Why? Because the average body size is larger, and recommendations are adapted to donors’ physiology.
It’s important to know that the volume collected never exceeds 13% of donor’s total blood volume. Additionally, standard volumes are always given with a margin of about ±10% to account for individual variations.
Conversely, in several Asian countries, the volume is reduced. In Vietnam, for example, a standard donation is 𝟯𝟱𝟬 𝗺𝗟. In China, donors can even choose: 200, 300, or 400 mL. These smaller volumes take into account average body weight, hemoglobin levels, and local medical standards.
These differences reflect not only morphological realities but also cultural and regulatory approaches to public health. Some countries favor more frequent donations but in smaller amounts, while others focus on larger volumes spaced further apart.
The same gesture, different contexts.
What remains universal is the importance of donation: whether 200 or 500 mL, every contribution saves lives.
And while the volume may change, the human value of the gesture remains constant.”
