Question regarding thyroid test results. My result is followed by Reference Range. Thyroxin (T4) Free, Direct S 0.90 ng/dL REF 0.82 - 1.77; TSH 4.170 uIU/mL REF 0.450 - 4.500; Thyroglobulin, Antibody less than 1.0 IU/mL REF 0.0 to 0.9; REVERSE T3, Serum 7.2 ng/DL REF 9.2 - 24.1; Thyroxin (T4) 6.6 ug/dL REF 4.5 - 12.0; Thyroid Peroxidase (TPO) Ab 9 IU/mL REF 0 - 34; Triiodothyronine, Free, Serum 2.5 pg/mL REF 2.0 - 4.4. Regarding TSH, I understand from various articles, the ideal range is 0.4 to 2.0 uIU/mL.

QUESTION: What does LOW (or High) REVERSE T3 mean? I would prefer to make any corrections to BOTH TSH and REVERSE T3 with Food and/or Supplements. I do not use SALT at home. Rarely eat out. No fast food. I eat salmon once or twice a week. I do not take Iodine.

I am 75 years old patientold, am 5' 2" and weigh 115 pounds. I take magnesium citrate/malate and Vitamin D3. Breakfast: Buckwheat or oatmeal cereal with ground flaxseed--no milk or sugar. Sometimes, 1 egg, I strip of bacon, and I slice of plain toast. LUNCH: 1 carrot, 2 celery, 1 apple (or half a grapefruit) and a bowl of tomato or barley soup. Sometimes, I have half a sandwich; roast beef or chicken salad on white bread. I have read that wheat is not all that good.) DINNER: 3 ounces of either chicken, turkey, salmon, or beef or salmon; 2 servings of vegetables. For Carbs, either brown rice, a boiled potato, or a small serving of angel hair pasta. A salad of cucumber, mushrooms, and romaine lettuce. On the salad and the carbohydrates, I use only Olive Oil. Occasionally, I have 1 glass of red wine.
