3 Endocrinology Calculators – HbA1c, HOMA-IR & Thyroid
Endocrinology calculators cover HbA1c-derived glucose conversion, fasting insulin-resistance arithmetic, and structured thyroid-function pattern assessment. These tools answer different laboratory questions.
Select by the required analytes, fasting or stability assumptions, assay context, and population. A converted value or biochemical pattern is not itself a diagnosis.

Choose a calculator by task
Use the task groups below to find the calculator whose formula, intended population, required measurements, and purpose match the task.
Glycemia and insulin-resistance arithmetic
Use HbA1c conversion for its population-level estimated average glucose relationship or HOMA-IR for paired fasting glucose and insulin arithmetic.
Thyroid-function pattern assessment
Use TSH with the required thyroid hormones and assay-specific reference intervals for a neutral biochemical pattern.
How to choose a calculator in this category
- Use HOMA-IR only with paired fasting inputs and preserve the laboratory methods and units stated on the page.
- Interpret thyroid results against the relevant laboratory reference intervals and the page’s required TSH, Free T4, and optional Free T3 inputs.
- Treat HbA1c conversion, HOMA-IR, and thyroid-pattern assessment as separate tasks rather than interchangeable endocrine screening.
Important limits
- Pregnancy, acute illness, medicines, assay interference, and altered red-cell turnover can change the relevance of endocrine laboratory results.
- HOMA-IR is method and population dependent and does not establish insulin resistance for an individual.
- These tools do not diagnose diabetes or thyroid disease, or select medication, targets, testing, or treatment.
