    I’m not in the field either, but based on my experience, you’re right. They also draw blood into small vials, the big bag is for giving/donating blood.

      and those small vials are sealed vacuums (or close to it. we pretend) to make the blood go in easier.

      when they break out the 100mL syringe, you know you’re in for it.
