Endocrinology Calculators
Endocrinology calculators cover HbA1c-derived glucose conversion, fasting insulin-resistance arithmetic, and structured thyroid-function pattern assessment. These tools answer different laboratory questions.

HbA1c / eAG conversion
A1C (HbA1c) & eAG Conversion CalculatorConvert HbA1c/A1C between NGSP percent and IFCC mmol/mol, calculate eAG in mg/dL or mmol/L, or express representative eAG as an ADAG-equivalent estimated A1C.Insulin-resistance arithmetic
HOMA-IR Calculator (HOMA1)Calculate the original HOMA1-IR index from paired fasting insulin and glucose, with glucose-unit normalization, assay limitations and no universal diagnostic cutoff.Thyroid-function pattern assessment
Thyroid Test Analyzer (TSH, Free T4 & Free T3)Analyze stable nonpregnant adult TSH and Free T4, with optional Free T3, against the reporting laboratory’s own intervals and show the resulting descriptive biochemical pattern.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.
