Why do I have to fast?
After eating, adjustments take place in the blood, specifically in degrees of glucose, lipids and iron. A fasting period of 10-12 hrs, generally overnight, reduces the irregularity in the degrees of these compounds (and others) in the blood. This guarantees that your test outcomes are not affected by your most current lump, and can be interpreted properly by the laboratory and medical professional.
Can I have anything to consume?
Yes-- water! A beverage of water is fine if you're really feeling thirsty. Nonetheless, your various other preferred beverages, consisting of tea and coffee, will have to stand by until after the test.
Can I take my normal drug?
In many cases you can continuously take your normal medicine as arranged, specifically if this is what you've provided for previous tests. If you are uncertain consult your medical professional. Certain medications could influence the results of fasting blood examinations, so it's up to your physician to determine just what is ideal for you.
What happens if I do not fast?
This is a time when you really should do as you're said to! It's essential to comply with the fasting directions so as to get precise test outcomes.
Many examinations are utilized to identify a clinical disorder, such as diabetic issues, so incorrect outcomes could possibly result in needless examinations or an incorrect diagnosis. If you do consume throughout the fasting period, it's important to inform the individual doing the blood test, so they can make a note on your record.
