Total Cholesterol Tests
The meter provides you with one measuring mode: General.
● Insert a test strip to turn on the meter. The screen will display
“ ”, a flashing “ ” and “CHOL”.
● After obtaining the first drop of blood, wipe it off. Squeeze again to
obtain another drop of whole blood as the sample for the test.
● The measurement unit used for indicating the concentration of blood
or plasma cholesterol can either have a weight dimension (mg/dL) or
a molarity (mmol/L). The approximate calculation rule for conversion
of mg/dL into mmol/L is:
mg/dL
Divided by
38.665
= mmol/L
E.g. 100 mg/dL ÷ 38.665 ≈
2.5 mmol/L
mmol/L Times 38.665 = mg/dL
E.g. 4.2 mmol/L x 38.665 ≈
162 mg/dL
Reference Values
The total cholesterol readings deliver plasma equivalent results and are
displayed in milligrams of total cholesterol per deciliter of blood (mg/dL)
or in millimoles of total cholesterol per liter of blood (mmol/L).
Total Cholesterol (mg/dL or mmol/L)
Desirable < 200 mg/dL (5.1 mmol/L)
Borderline High 200 - 239 mg/dL (5.1 - 6.1 mmol/L)
High
≥ 240 mg/dL (6.2 mmol/L)
A healthcare professional will discuss values that are specifically
appropriate for each patient. At least two measurements of cholesterol
in separate occasions should be made before a medical decision is
made, since a single reading may not be representative of a patient’s
usual cholesterol concentration. An elevated cholesterol level is only
one risk factor for heart disease. There are many others. A cholesterol
less than 200 mg/dL is desirable.
