Blood cholesterol test
Blood cholesterol levels can be measured with a simple blood test. You may be asked not to eat for 12 hours before the test (which usually includes when you’re asleep) to ensure that all food is completely digested and won’t affect the result, although this isn’t always necessary.

Blood sugar (glucose) tests
A number of tests can be used to diagnose and monitor diabetes by checking the level of sugar (glucose) in the blood.
These include the:
- fasting glucose test – where the level of glucose in your blood is checked after fasting (not eating or drinking anything other than water) for at least 8 hours
- glucose tolerance test – where the level of glucose in your blood is checked after fasting, and again 2 hours later after being given a glucose drink
- HbA1C test – a test done to check your average blood sugar level over the past 3 months
