Desiree,
I don't know how well you know this Doctor's office and I'm not sure it matters. But, I think I would leave a message for a call back from the doctor.
They ususally call back at the end of their day. I'd explain that you are unsure, anxious and frightened and getting the results delayed is adding to the stress. See if he'll intervene (sp)with the lab. After all they should want to keep him happy so he continues to refer to them.
It can't hurt to ask. My last go round with my gastro he had people giving him results in a day. This is scans, blood, mri's and such. Still don't know how he pulled that off.
And if he doesn't help, come back and vent....
Take care,
Dinah
