What this calculator does
Total cholesterol to HDL ratio works out a single number summarizing cardiovascular risk from a lipid panel. Enter your own figures above and the answer updates as you type: nothing is fixed in the code, so the result reflects exactly the numbers you supply.
The formula this calculator evaluates is printed under the tool and explained below, so you can check the working by hand or reuse it in a spreadsheet.
