Versioned calculationFormula v1.0.0
Method
Apply the official point table, including the Asian-American BMI threshold.
Important boundary
The score screens risk and cannot diagnose current glucose status.
Answer the official risk itemsUse the labeled field and matching unit.
Apply CDC pointsThe calculator applies the displayed method at full precision.
Use blood testing for diagnosisKeep the stated boundary beside the result.
Interpretation
The total is the CDC questionnaire score.
BMI and component points stay visible for auditability.
A score cannot replace an A1C, fasting glucose, or clinician assessment.

Recorded method
Trace every point to the CDC scoring page and test age, BMI, sex/history, and five-point boundaries.
These records describe the published model and reference tests. A test-case count is not a certification of every possible input or an independent specialist review. Editorial policy
Known limitations
- Self-reported risk factors can be wrong or incomplete.
- The score does not include a laboratory measurement.
- Population risk is not individual diagnosis.
- Pregnancy and pediatric use are outside this adult screen.

What the CDC Prediabetes Risk Test Calculator calculates
Calculate the current CDC Prediabetes Risk Test score from its published questionnaire items.
The calculator reproduces the CDC screening score and keeps diagnosis outside the result.
Start with the Health calculators hub when a neighboring workflow better matches the question.
How to use the CDC Prediabetes Risk Test Calculator
- Enter age and the listed history items.
- Select whether the CDC Asian-American BMI threshold applies.
- Enter height and weight for BMI points.
- Use the score to decide whether to seek appropriate blood testing.
Continue with the A1C Calculator. Convert A1C and estimated average glucose.
Formula, variables and calculation order
total = age points + sex/history point + family-history point + blood-pressure point + inactivity point + BMI points.
Inputs are validated and normalized before the calculation. Working precision is retained until display rounding.
For a separate method, open the Blood Pressure Calculator. Classify a measured blood-pressure pair.
Worked example and boundary check
Worked example
Age 45, family history, high blood pressure, inactivity, and BMI 29 produces a score at or above the 5-point threshold.
Boundary check
BMI points begin at 23 for the Asian-American path and 25 for the standard path on the CDC scoring page.
How to interpret the result
Five or more means the CDC screen identifies significant risk; it does not say the person has prediabetes.
- Self-reported risk factors can be wrong or incomplete.
- The score does not include a laboratory measurement.
- Population risk is not individual diagnosis.
- Pregnancy and pediatric use are outside this adult screen.
Compare the result with the Cholesterol Ratio Calculator. Calculate common lipid ratios.
Frequently asked questions
Does 5 points mean I have prediabetes?
No; only blood testing diagnoses it.
Why is the BMI threshold different?
The CDC score applies a lower first BMI threshold for Asian Americans.
Can a low score rule out diabetes?
No.
What should I do with a high score?
Follow the CDC advice to seek appropriate testing and clinical guidance.
