Anion gap 2. sodium normal. moms sis died from multiple myeloma. should i be concerned? just got test back. 57 years old. tsh 0.20 i'm on synthroid (thyroxine)

If your TSH: is consistently low, you need to have your doctor reduce your dose of Synthroid (thyroxine) and recheck your levels after six weeks or more.

Not really.: A low anion gap is not something we worry about. It's true that sometimes people with multiple myeloma can have a low anion gap because their protein is high and their albumin is low. But having the blood sit too long also causes a low anion gap. What is your protein and albumin? Having a low TSH when taking Synthroid (thyroxine) can mean the dose is too high, but it depends on the reason you take It.
