Endocrinology & Diabetes Clinical Calculators

Why This Matters

Diabetes mellitus affects over 537 million adults globally, with projections exceeding 780 million by 2045. Thyroid nodules are found in up to 68% of adults on ultrasound. Metabolic syndrome affects approximately 25% of the global population. Early risk stratification using validated tools like FINDRISC and ATA thyroid nodule classification enables timely intervention and improved clinical outcomes.

When to Use

Use FINDRISC for type 2 diabetes risk screening in asymptomatic adults. Use HbA1c to eAG for patient education and goal setting. Use ATA Thyroid Risk for evaluating thyroid nodules on ultrasound. Use the Metabolic Syndrome calculator for diagnostic classification according to IDF and ATP III criteria.

Available Endocrinology & Diabetes Calculators

• ATA Thyroid Risk

  The American Thyroid Association (ATA) ultrasound risk stratification system categorizes thyroid nodules based on sonographic patterns to determine the need for fine-needle aspiration (FNA) biopsy.

• Metabolic Syndrome

  The National Cholesterol Education Program (NCEP) Adult Treatment Panel III (ATP III) defines metabolic syndrome as the presence of ≥3 of 5 specific criteria: elevated waist circumference, elevated triglycerides, reduced HDL cholesterol, elevated blood pressure, and elevated fasting glucose.

• HbA1c to eAG

  The HbA1c to eAG converter translates a patient's HbA1c percentage into an estimated Average Glucose (eAG) in both mg/dL and mmol/L. Developed from the ADAG study, this tool helps communicate glycemic control in the same units used for day-to-day glucose monitoring.

• FINDRISC

  The FINDRISC (Finnish Diabetes Risk Score) is a validated screening tool for identifying individuals at risk of developing type 2 diabetes within 10 years. Developed from a Finnish population study, it uses eight simple questions to estimate diabetes risk without laboratory tests.

• DKA Severity

  Diabetic Ketoacidosis (DKA) is a life-threatening complication of diabetes mellitus characterized by hyperglycemia, metabolic acidosis, and ketosis. This calculator classifies DKA severity based on ADA criteria and provides evidence-based management recommendations.

• QUICKI

  QUICKI (Quantitative Insulin Sensitivity Check Index) is a simple, validated index for assessing insulin sensitivity derived from fasting glucose and insulin concentrations.

  Calculate →

• HOMA-IR

  HOMA-IR is a validated method for quantifying insulin resistance and beta-cell function from fasting glucose and insulin concentrations. It is widely used in clinical research and practice.

  Calculate →

• Insulin Correction Dose

  The insulin correction dose (also called correction bolus or supplemental dose) is the amount of rapid-acting insulin needed to bring elevated blood glucose down to target level, based on the individual's insulin sensitivity factor (correction factor).

  Calculate →

• TI-RADS Score

  The American College of Radiology (ACR) Thyroid Imaging Reporting and Data System (TI-RADS) is a standardized classification system for thyroid nodules based on ultrasound features. It assigns points for composition, echogenicity, shape, margin, and echogenic foci to stratify malignancy risk and guide FNA decisions.
