What is the difference between a fasting and non-fasting blood test?
A fasting test gives you a ‘bottom line’. This is the lowest you can expect the sugar and cholesterol figures to be. If you have just eaten then the levels of sugar and cholesterol are determined by what you have just eaten – not by your body’s ability to handle these substances. If a non-fasting level is high, it might not mean anything at all is wrong. If a fasting level is high, then something is definitely wrong.
