Normal thyroid lab studies.: Your thyroid lab studies are within normal limits on whatever dose of Synthroid (thyroxine) you are now taking. Hypothyroidism particularly if due to Hashimoto's thyroiditis can be associated with other autoimmune entities such as pernicious anemia characterized by low B12 levels. in that situation B12 must be administered either sublingually daily or intramuscularly on a monthly basis. Active menses?
