According to Mayo Clinic, a desirable total cholesterol level is lower than 200 mg/dL for both men and women.
While rare, a total cholesterol level could be considered too low. However, there isn't yet a consensus among medical professionals on what would constitute such a level.
Total cholesterol is typically determined by the formula HDL level + LDL level + 20% of triglycerides level.
A total cholesterol level of 457 may be written on a lab report as 457 mg/dL, or milligrams per deciliter. This means there would be 457 milligrams of total cholesterol per deciliter of blood. For reference, 1 deciliter is equal to 100 milliliters, or approximately 3.38 US fluid ounces.
Total cholesterol is typically measured by a blood test, also called a lipid profile or lipid panel, ordered by your doctor. To get an accurate reading, you're typically asked to fast for at least 8 to 10 hours prior to the test.
You can also measure total cholesterol levels at home with a digital cholesterol meter. To use one, you typically prick a finger with a lancet or fingerstick, add a drop of blood to a test strip, and insert the strip into the meter. While convenient, the reliability of readings from at-home cholesterol meters is debated.
