How to use the Cholesterol Calculator

What this calculator does
The route assigns categories with strict cutoffs: total <200 desirable, <240 borderline high, otherwise high; LDL <100 optimal, <130 near optimal, <160 borderline high, <190 high, otherwise very high; HDL >=60 excellent, >=40 normal, otherwise low; triglycerides <150 normal, <200 borderline high, <500 high, otherwise very high.
Formula and method
The route assigns categories with strict cutoffs: total <200 desirable, <240 borderline high, otherwise high; LDL <100 optimal, <130 near optimal, <160 borderline high, <190 high, otherwise very high; HDL >=60 excellent, >=40 normal, otherwise low; triglycerides <150 normal, <200 borderline high, <500 high, otherwise very high. It counts four threshold flags and maps 0, 1, 2, or 3-4 flags to Low, Moderate, High, or Very High Risk.
Variables and inputs
Enter total cholesterol, LDL, HDL, and triglycerides in mg/dL. The UI accepts nonnegative values and does not ask for age, sex, smoking, blood pressure, fasting status, medications, or prior cardiovascular disease.
Worked example
For total 200, LDL 100, HDL 55, and triglycerides 120 mg/dL: total is Borderline High because the engine uses `< 200` for Desirable; LDL is Near Optimal because 100 is not below 100; HDL is Normal; triglycerides are Normal; and the four-flag count is 0, producing Low Risk.
How to interpret the result
The result is a side-by-side classification of lipid values plus a simple count of selected flags. The Low Risk label is not a full cardiovascular-risk assessment, and a favorable category in one lipid does not cancel an unfavorable value in another.
Common mistakes to avoid
Watch the strict boundary at 200 total and 100 LDL, enter all four values in mg/dL, and do not infer that high HDL makes every other result safe. Follow the preparation instructions attached to the actual lipid test, especially when triglycerides are involved.
Assumptions and limitations
The risk score counts only four threshold conditions and omits age, blood pressure, diabetes, smoking, kidney disease, family history, medications, non-HDL cholesterol, and prior events. It does not determine treatment targets, and it does not validate whether the panel was fasting or clinically interpretable.
