A member asked:
After my daughter got six tubs of blood taken out she feels weak and headache. she did pass out after they drew the blood.?
A doctor has provided 1 answer
Likely illness Sx: Six tubes or about 2 tablespoons of blood are not enough to cause instability in anyone over about 40 lb.If the person fainted at the time blood was drawn it is likely just the fainting response all can have, not the volume taken.Persistence of any faint feeling & headache can also be due to a combination of feeling unwell, stress, fatigue, poor hydration & reaction to the draw.
