Estimate your thyroid basal metabolic rate (BMR) using pulse rate and pulse pressure to assess the risk of hyperthyroidism or hypothyroidism.
Enter blood pressure and pulse data.
Gale Formula: BMR% = (Pulse Pressure Difference + Pulse Rate) - 111. This is an empirical formula, for reference screening only, and cannot replace laboratory thyroid function tests.
Creatinine Clearance Calculator
Enter your age, weight, and serum creatinine to quickly assess your kidney function.
Fetal Weight Calculator
Estimate fetal weight using ultrasound measurements (BPD, AC, FL) with multiple standard obstetric formulas.
Child Height Predictor Calculator
Predict a child's potential adult height range based on parents' heights and gender, providing parents with a reliable growth trend reference.
If you suspect you may have abnormal thyroid function (such as hyperthyroidism or hypothyroidism), this tool can quickly estimate your thyroid basal metabolic rate (BMR) using simple physiological indicators. The thyroid basal metabolic rate refers to the minimum energy expenditure required to maintain basic life functions at rest. The calculation formula combines pulse rate (beats per minute) and pulse pressure (systolic pressure minus diastolic pressure) to generate a value and provide a functional status assessment.
What is a normal thyroid metabolic rate?
The normal range is typically ±15%. Formula results between -10% and +10% are generally considered normal.
Can the calculation results replace a medical exam?
No. This tool only provides a preliminary screening reference. A definitive diagnosis requires laboratory tests such as serum TSH, FT3, and FT4.
You must sit quietly for 15 minutes before measuring. Results will be inaccurate during pregnancy, if you have a fever, or after strenuous exercise. If your calculation results are abnormal, it is recommended to seek medical attention as soon as possible.
Typical input example: Pulse rate 72 bpm + Pulse pressure 38 mmHg ≈ Metabolic rate +5% (Normal). Note that patients with hyperthyroidism often have a pulse rate >90 bpm accompanied by an increased pulse pressure, while the opposite is true for hypothyroidism. It is recommended to monitor continuously for 3 days and take the average value.
