Re: What is difference between TSH and TSH Cascade?
If you'd been up for 6 hours, your TSH is prolly like 6+ as you first get up. the TSH drops throughout the day.
my TSH after being up for about 30 minutes was 4.565. After being up for about 4 hours, it was 2.61. About 6 hours, it was 1.91.
I would suggest you have your blood taken as soon as you get up in the morning as your TSH is at its maximum.
I was recently diagnosed hypo last week. Based on TSH alone.
Good luck and I hope that your doctor isn't an idiot like 99% of them. (I went through 4, and I was lucky then!)
