About this tool
The total-to-HDL ratio packs two cholesterol numbers into one figure that many clinicians glance at first. Enter total cholesterol and HDL in the same unit and the tool divides them. Lower ratios are generally viewed more favourably, but this is general information, not personal medical advice.
Frequently asked questions
Which units should I use?
Any unit works as long as total and HDL use the same one, since the unit cancels in the division.
Does this replace a lipid panel review?
No. It is a summary figure, not a substitute for reviewing all the results.
