The Triglyceride/HDL Cholesterol Ratio. What Is Ideal?
The TG/HDL-C ratio can easily be calculated from the standard lipid profile. Just divide your TG by your HDL-C.
However, when looking at the ideal ratio, you have to check if your lipid values are provided in mg/dl like in the US or mmol/L like in Australia, Canada, and most European countries.
If lipid values are expressed as mg/dl (like in the US);
TG/HDL-C ratio less than 2 is ideal
TG/HDL-C ratio above 4 is too high
TG/HDL-C ratio above 6 is much too high
If you live outside the US or are using mmol/L, you have to multiply this ratio by 0.4366 to attain the correct reference values. You can also multiply your ratio by 2.3 and use the reference values above.
If lipid values are expressed as mmol/L (like in Australia, Canada, and Europe);
TG/HDL-C ratio less than 0.87 is ideal
TG/HDL-C ratio above 1.74 is too high
TG/HDL-C ratio above 2.62 is much too high
