With a TSH level on 3/15 was. 1 taken again on 4/17 the result was. 40, my current doctor does not appear to be worried, should I be?

TSH. Tsh levels can fluctuate based on various factors. Are you taking medications such as levothroxine for hypothyroidism? If so, your second TSH result. 40 is within the recommended target range. If you are not taking levothyroxine, your first result. 1 is slightly on the lower side, you may have subclinical hyperthyroidism. So it would all depend on the context. Talk to your doctor.
No. These levels are normal. Ranges to worry about are 5-10. Treatment may not be indicated until the level is over 10.
