Method
Evaluate each measurement or treatment flag, then count the criteria present.
Important boundary
A calculator cannot verify fasting status, medications, lab quality, or alternate population thresholds.
Enter measurements and treatment flagsUse the labeled field and matching unit.
Evaluate all five criteriaThe calculator applies the displayed method at full precision.
Confirm clinicallyKeep the stated boundary beside the result.
Interpretation
The primary result is a transparent criterion count.
Individual criterion flags show why the count changed.
Three or more is a screening rule, not a self-diagnosis.

Recorded method
Test all threshold equalities, sex-specific waist/HDL branches, treatment OR logic, and count classification.
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
- Uses the displayed NHLBI default waist thresholds.
- Cannot verify fasting status or medication indication.
- Does not estimate probability or future events.
- Pregnancy, acute illness, and pediatric use require different interpretation.

What the Metabolic Syndrome Criteria Checker calculates
Count the five NHLBI metabolic-syndrome criteria using measurements and relevant treatment flags.
The checker makes each criterion auditable and does not invent an overall disease probability.
Start with the Health calculators hub when a neighboring workflow better matches the question.
How to use the Metabolic Syndrome Criteria Checker
- Select the displayed sex-specific thresholds.
- Enter a waist, blood-pressure pair, fasting glucose, HDL, and triglycerides.
- Mark only medicines that address the named criterion.
- Review the count with a qualified clinician.
Continue with the A1C Calculator. Convert A1C and estimated average glucose.
Formula, variables and calculation order
count = waist + blood pressure + fasting glucose + triglycerides + low HDL, where each component is 0 or 1 under the displayed NHLBI rule.
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
A high waist, triglycerides of 160 mg/dL, and HDL below the sex-specific threshold produces three criteria even when blood pressure and glucose are below threshold.
Boundary check
Waist thresholds can differ by ethnicity and guideline; the default NHLBI values are shown, not silently generalized.
How to interpret the result
Three or more listed criteria meets the displayed screening definition, but measurement context and clinical confirmation still matter.
- Uses the displayed NHLBI default waist thresholds.
- Cannot verify fasting status or medication indication.
- Does not estimate probability or future events.
- Pregnancy, acute illness, and pediatric use require different interpretation.
Compare the result with the Cholesterol Ratio Calculator. Calculate common lipid ratios.
Frequently asked questions
Does three criteria prove a diagnosis?
It matches the displayed screening definition but still needs clinical confirmation.
Why include medicine flags?
Treatment can satisfy a criterion even when the current measurement is controlled.
Are waist cutoffs universal?
No.
Does the tool calculate heart-disease risk?
No.
