A 56-year-old member asked:

No: These are both from the same medication class, beta-blockers. It would be extremely unusual for a physician to prescribe these simultaneously and could be potentially very dangerous. You should absolutely clarify with your physician whether this was intentional and if so, what the reason was for prescribing them both together.
A 52-year-old male asked:

Probably not: People with graves disease typically have a low TSH along with high free T4 and/or high free t3 (liothyronine). Most people also have a high tsi titer, though not everyone does. If you have a low TSH and high free t4, you may have mild early hyperthyroidism, and it is possible that it is graves, so it is something to follow-up in the future. A more accurate antibody test than tsi is the TSH receptor antibody.

Don't worry about it: As long as your hemoglobin is normal, don't worry about your mch, as it doesn't really matter. If you don't have an anemia, then the MCH is not important. Mch stands for mean corpuscular hemoglobin, which is the average mass of hemoglobin in a red blood cell.

Thanks for your quick reply! Thank you for your time and answer, a lot to think about. When tested 20 yrs ago it was very low, in the 2's, now it's 4/5. Same symptoms.
