When you're told to fast for a test, you may be confused what it all entails. You may fast for a test ordered by your doctor or for a test through Prairie Lakes' direct lab access program.
The American Society for Clinical Laboratory Science provides fasting FAQS below, if you have questions please ask your physician or you may call our lab before your test at 605-882-7750.
Can I have black unsweetened coffee during my fast?
No, the caffeine in coffee and other beverages can temporarily raise blood sugar levels.
Why can’t I exercise?
Exercise can raise your cholesterol and also affects blood sugar.
But smoking – that’s not food?
Smoking can raise “bad” cholesterol and can raise your blood insulin, changing blood sugar levels.
Surely sugar free gum won’t matter?
Fasting means no calories, and sugar free gum may have calories. Gum also stimulates your digestive system and may affect test results. Same goes for sugar free beverages.
What if I slip up and have something I shouldn’t?
Discuss it right away with your health care professional. Most likely you will need to repeat your fast and return on a different day to get accurate results.
Do I need to fast for just a total cholesterol?
Fasting is not necessary for total cholesterol, but is necessary if you have HDL, LDL or triglycerides done.
