Hi,
Advice from CD:
Q: Is it all right to continue the ‘Sole Source’
programme if giving blood?
A: The ‘Sole Source’ programme should not be followed for
one week preceding blood donation and for one week
after. In fact, a centre will refuse to take blood if
they know the donor is on a very low calorie diet,
because blood viscosity and volume are affected by the
‘Sole Source’ programme.
