Marcos Umino Shares His 2025 Donation Goals: 15 Plasma Donations,13L of plasma!
Marcos Umino, Senior Customer Experience Engineer at Microsoft, posted on LinkedIn:
“That’s the last plasma donation for this year. 15 plasma donations, 879mL each bag, that’s about 13L of plasma!
According to CoPilot, a 80 kg adult male typically has about 3.2 – 4.0 L of plasma. I donated my plasma volume at least 3 times over this year. Average statistics, each plasma donation saves 3 lives. I hope I helped at least 45 people.
I am not bragging. I am calling you. Help this world be a better place, help it believe it is worth fighting for. Help it believe good exists without asking for nothing back.”
