Honey, I'm so sorry you had to go through this.
As others have said, I wouldn't accept this at face value, either. You pass a physical, and your lab work says your thyroid, blood, and kidneys have issues? What kind of issues? Why did they test for TSH? What wrong with your blood work? Hematocrit low (anemia?), clotting time? And the kidneys - what was up with that? Was it your GFR? My GFR is low, like below 50 (< 60 is supposed to mean "chronic kidney disease"), and my doctor and surgeon were both okay with it.
This stinks that this happened one week before your scheduled surgery! How was that even possible? My surgeon requires lab results at least one month before the surgery date. Okay, so let's get past that. Maybe you have to reschedule your surgery, but you have to wipe away the tears and gather your inner strength here, sweetie. Start looking for paths forward.
First of all, if you don't know already, you need to find out exactly what the issues are, and by all means get your doctor to order new labs. Then, depending on the results you make a new plan. Never give up!
With kindness,
Terri
