What should I do if I feel lightheaded after a blood draw for the HbA1c test?

If you feel lightheaded after a blood draw, sit down for a few minutes and drink some water. Feeling dizzy after a blood draw can happen, especially if you’re nervous or dehydrated. Let the healthcare professional know if you feel faint so they can help you. Most people recover quickly after resting for a few minutes. To reduce the chances of dizziness, stay well-hydrated before your appointment, and let the lab technician know if you’ve had issues with blood draws in the past.
