HOMA-IR Calculator
Estimates insulin resistance from fasting plasma glucose and fasting serum insulin using the Homeostasis Model Assessment (HOMA) equation.
EndocrinologyHOMA-B Calculator
Estimates pancreatic beta-cell function from fasting plasma glucose and fasting serum insulin using the HOMA equation.
EndocrinologyInsulin Sensitivity
Provides a simple estimate of insulin sensitivity as the reciprocal of HOMA-IR.
EndocrinologyEstimated Average Glucose (eAG)
Estimates mean plasma glucose from HbA1c using the ADAG formula validated by the American Diabetes Association.
EndocrinologyTriglyceride-Glucose (TyG) Index
Calculates the triglyceride-glucose (TyG) index, a surrogate marker of insulin resistance derived from fasting triglycerides and fasting plasma glucose: TyG = ln(TG × FPG / 2) with units in mg/dL. Elevated values indicate greater insulin resistance and higher cardiometabolic risk.
EndocrinologyTriglyceride to HDL Ratio (TG/HDL)
Calculates the ratio of fasting triglycerides to HDL cholesterol. A ratio ≥ 3.0 (mg/dL units) has been used as a marker of insulin resistance in overweight non-diabetic adults. The predictive value is ethnicity-dependent and is not reliable in African American populations.
EndocrinologyQuantitative Insulin Sensitivity Check Index (QUICKI)
Calculates QUICKI, an index of insulin sensitivity derived from fasting insulin and fasting glucose: QUICKI = 1 / (log10 fasting insulin [µU/mL] + log10 fasting glucose [mg/dL]). Lower values indicate greater insulin resistance; the index is primarily a research and screening tool.
EndocrinologyCorrected QT
Corrects the QT interval for heart rate using the Bazett formula.
EndocrinologyLevothyroxine Dose Calculator
Estimates levothyroxine dose for thyroid hormone replacement, accounting for patient age and cardiac risk factors.
EndocrinologyAdrenal Steroid Converter
Converts between equivalent glucocorticoid and mineralocorticoid doses of commonly used adrenal steroids.
EndocrinologyFree Thyroxine Index (FTI / T7)
Calculates the free thyroxine index (FTI or T7) from total T4 and the T3 resin uptake, an indirect estimate of free thyroid hormone used when direct free T4 assays are unavailable or when binding-protein status is in question.
EndocrinologyMetabolic Syndrome (ATP III Criteria)
Assesses metabolic syndrome using the updated NCEP ATP III criteria, which require at least 3 of 5 components: elevated waist circumference, elevated triglycerides (or treatment), reduced HDL (or treatment), elevated blood pressure (or treatment), and elevated fasting glucose (or treatment).
