Can I Drink Coffee While Fasting For Blood Work
If having blood work done for physical in morning can you drink water before? Doctor said no food or coffee
Fasting labs are generally aimed at looking at blood lipid and glucose levels. These would generally be unaffected by moderate water intake prior to testing. Actually, being dehydrated when the sample is drawn may more likely cause abnormal values.
A caution would be if you were to drink excessive amounts of water and diluted your blood. This would be unlikely in normal circumstances. ...Read more
Is it really big deal if I have cream in coffee 7 hrs before fasting blood work? I find it hard to believe that could badly mess with results.
Fasting Blood Work: Well it may or may not "mess with the results" as you say. It depends on what is being tested for. Are you waiting until afternoon to get the blood work done because that is when your appointment is? Why not go to the office as soon as they open to get your blood work? Then you can have your coffee and cream. If your fasting sugar is 125 you don't have diabetes, if 126 you do. Any difference? ...Read more
Yes: Drinking water is fine unless directed specifically by your physician to avoid it. Fasting lab is looking for blood sugar and cholesterol which would be affected by coffee, food, and milk. I usually recommend to my patients to take their routine meds even when fasting except for medications that would affect the blood sugar. ...Read more
I had lab work done. My blood sugar level can back high. Was fasting blood work & didn't drink any water, would that cause the sugar level to be high?
Try Not: Fasting for thyroid tests not usually needed so perhaps you are also having lipids, cortisol or blood glucose as well. Best if only water for the 12 hours prior to fasting tests. Some evidence that perhaps caffeine can impact blood sugar very slightly (though may be insignificant). Some sources of coffee (eg via percolator) have oils that raise triglyceride levels. Wait for that cup if you can. ...Read more

Dad has been drinking whiskey 200 ml every day for the past 20 yrs, blood work last week was perfectly fine, how is this possible?
He's lucky?: One study showed that alcoholics who drank coffee on a regular basis seem to have less liver damage. He may have avoided other meds such as tylenol (acetaminophen) with the alcohol and some is just genetic. Other people who drank the same could have liver problems. Some times I am amazed as well with some of my alcoholic patients, however while the liver looks good, not all is well in their lives. ...Read more

Could drinking kombucha tea once, day before blood work was done, raised my GGT to 157 following day?
That'd be a first: You're the guy with the elevated RDW, correct? Some folks always run a high GGT -- it's genetic. Your ropinirole isn't noted for raising GGT but medications can do this unpredictably. More worrisome causes of high GGT include liver tumors -- these would typically also elevate your alkaline phosphatase. ...Read more
Can you drink alcohol while on methotrexate? And how often do you need to get blood work done while on it?
Not recommended-3 mo: Drinking alcohol while on Methotrexate is not recommended. Methotrexate can sometimes cause liver damage and, since alcohol can also cause liver damage, this is why mixing the two is not recommended. Now, having said that, an occassional alcoholic beverage is not totally forbidden, but you shouldn't make a habit of it. The typical interval for liver testing while on Methotrexate is every 3 months. ...Read more

I am 21 years old and recently had some blood work done my AST was 36 and ALT 58. Both slightly elevated. I don't drink a lot does this raise concern?

Good luck! ...Read more
