Tools for diabetes and thyroid management including HbA1c-to-glucose conversion, insulin correction dose calculation, and TSH interpretation. Designed for clinicians and patients managing endocrine conditions.
This category currently includes 5 tools, including HbA1c Converter, Insulin Correction, and TSH Interpreter.
These resources are built for clinicians, trainees, and medically informed patients who need fast bedside calculations. Use the results as decision support and pair them with full clinical context and local guidelines.
Convert HbA1c to estimated average glucose (eAG): 6%=126 mg/dL, 7%=154, 8%=183, 9%=212. ADA 2026 target <7% for most adults with diabetes. Shows both mg/dL and mmol/L.
Calculate the insulin correction factor (sensitivity factor) using the 1800 and 1500 rules. Determine how much 1 unit of insulin lowers blood glucose.
Interpret TSH and free T4 to assess thyroid function. Normal TSH: 0.4–4.0 mIU/L. Identifies overt and subclinical hypothyroidism, hyperthyroidism, and euthyroid sick syndrome.
Estimate the starting levothyroxine dose for hypothyroidism: ~1.6 mcg/kg/day for full replacement, ~25–50 mcg/day for subclinical hypothyroidism. Recheck TSH at 6–8 weeks.
Convert between corticosteroid doses by anti-inflammatory potency equivalence: prednisone 5 mg = hydrocortisone 20 mg = methylprednisolone 4 mg = dexamethasone 0.75 mg.
