I'm expecting AF today and I'm suppose to get CD3 bloodwork done. I've read CD4 is ok too. If I count today as CD1, Sunday would be CD4 but if I go by 24-hr periods, Monday would be CD4. Which is it?
I think the closest you can get in to the Dr. is the day you should go with...I think there won't be a huge downside to getting BW on cd4 vs. cd3. ?I've known of people getting it on cd5 w/o issues.
If AF does infact show today, I would think Sunday because the first day of red flow is CD1 even if you start late in the day. I would just call the doctor to schedule the blood work and ask them at that time which day would be more appropriate.
