Do I Have To Fast For A Hb A1c Blood Test
Not really: The aic test generally tells us what has been going on with your sugar over the past 3 months approximately. One does not really have to fast for it, but it is best done fasting in my opinion, because your doctor will probably want to see a fasting blood sugar at the same time to help manage your diabetes. Often a lipid panel is done at the same time, which requires one to be fasting. ...Read moreSee 1 more doctor answer
I have a blood test tmrw afternoon to check my vitamin d. When do you have to fast for a blood test? I don't have to right? I forgot to ask. Thanks.
Not necessary but...: No, you do not have to fast for this test, but it is wise to not eat much within a couple of hours of any blood test as shortly after a meal your blood will be loaded with triglycerides which reduces the amount of serum available for testing. So i advise either eating a light lunch or waiting about 3 hours after eating- but that is not absolutely essential. ...Read more

How long will it take for contine to get out my blood stream? Im a heavy smoker an i have to pass a blood test to confirm that im not smoking.
48-72 hours: Nicotine is a very short-acting drug and is metabolized quickly, which is why people who smoke have a cigarette generally at least once every 45 minutes while awake. However, its metabolite cotinine lasts longer, and can be detected for about 2 days after quitting smoking. It depends to some extent on whether you are a half-pack/day or a 3-pack/day person, but 72 hours is usually maximum. ...Read moreSee 1 more doctor answer
I have a consistent high blood pressure i was advice to consult and have a cardio test. How much is it?
Certainly: Unfortunately donor pool will be much smaller than if you were rh +ve.Any chance there is relative with o-ve blood type who might donate. Another option can be arranged via some organ banks, whereby a potential donor with non matching blood type or tissue match can be matched to third party who also has a non-matching donor, but their donor matches you & your donor matches them. ...Read more

What to do if I have had blood test done for a physical, and my potassium levels are very high. Any help?
Get it rechecked: It is probably a lab error. It is not uncommon to have this false alarm because potassium level does not go up if you are well. It usually goes up if your kidney is not functioning. Most of the false alarms are caused by a difficult blood draw which can dmage the red cells which relase potassium into the blood. But it is nothing to worry about..You just need to confirm it. ...Read more
