I agree with Bubbles/Celeste. As someone that works directly with clinical research data, lab ranges are an insteresting beast. There is normal and then there is "normal" based on things like gender, ethnicity, height, weight (depending on what you are measuring for and which disease state). So what could be a lab range that one clinic is using, might not be the normal for you anyways. We usually confirm our lab ranges with investigators, etc.depending on multiple variables and many many other factors. So there can be bigger sweet spots than people think sometimes. AND…..TSH can be even more complex as an endicronologist might have a different range for what they consider normal from another type of physician. Some consider anything in the lab range as normal and some consider values in the range as subclinical depending on the number. TSH outside of melanoma, has a lot of stuff going on. I've had mine tested one week apart (I'm not on anything or any treatments for anything, my husband has melanoma) and gotten two very different values.
Plus the drugs can mess it all up as we all know. When I was in dialysis research, the dialysate and treatemtn could mess up electrolytes/hemoglobin and then you needed EPO, potassium etc.. YADA YADA YADA It's a balancing act at times. I used to think of it as a cascade of events from point of treatment.
It's a real roller coaster at times, so Normal is good at any point!
The scanxiety is real, allow yourself to know that it's hard to control the anxiety at times, especially before scans. In reality, who the heck WOULDN'T be nervous going through all this. It's big stuff.
