SparklyUnicorn Posted November 14, 2016 Share Posted November 14, 2016 I do not know which tests I'm having. I was just told to fast. Problem is I stopped eating at 5:30 tonight and this test isn't happening until after 10:30 tomorrow morning. Do you think that is too long? Should I mention it? You'd think they would have scheduled this test a bit sooner in the day. I avoid eating too close to bed time because of the reflux so having a snack at 10 tonight is really not a good idea. See this whole thing is irritating the heck out of me. No useful guidelines. No consideration for what works for me. Just willy nilly nonsense. They could have scheduled this part at a lab prior to this. Now I may go and waste my time. Maybe it's not a big deal. I really do not know though.

Cinder Posted November 14, 2016 Share Posted November 14, 2016 (edited) I've been told nothing for at least 12 hours before testing except water and unsweetened black coffee/tea were allowed. Most days I can manage to go at least 12 hours without food as long as I have something to drink. ETA: do you have to go to the lab that late? Our doctor's office allows you to drop in for lab draws (on site). Dh (who gets them way more often than I do) usually goes in at 8am a week before his doc appt.

I just don't know if that is ideal for these tests. Quote Link to comment Share on other sites More sharing options...
marbel Posted November 14, 2016 Share Posted November 14, 2016 You could call the on-call doctor and ask for specific information. Or, call the office first thing in the morning? Though maybe that will be too late. Does your office schedule the blood tests for you? The way it works here, we get the prescription for the test, then make our own arrangements with the lab (if the lab takes appointments; some do, some don't). Anyway, sorry it is not working out well. I hope you get it resolved quickly! 1 Quote Link to comment Share on other sites More sharing options...

Guest Posted November 14, 2016 Share Posted November 14, 2016 You want at least twelve hours of no food, but longer is fine. I had a fasted blood glucose a few weeks ago and stopped eating at 7-ish but the blood draw wasn't until 2:15. I drank a lot of water and was quite hungry but it didn't hurt anything :) Quote Link to comment Share on other sites More sharing options...
maize Posted November 14, 2016 Share Posted November 14, 2016 Longer than 12 hours is fine, it's the minimum that matters. 1 Quote Link to comment Share on other sites More sharing options...
hornblower Posted November 14, 2016 Share Posted November 14, 2016 Longer will be fine. If I were you, I'd ask to do the blood draw lying down. Fasting draws are more likely to make people feel woozy and since you're doing an extra long fast I'd take an extra precaution. fwiw, the common tests requiring a fast are glucose ( ie diabetes testing) & lipid panels. 1 Quote Link to comment Share on other sites More sharing options...

Code Lyoko Posted November 15, 2016 Share Posted November 15, 2016 Agree with the others, longer is fine, it is the minimum that must be met (usually no food for 12 hours prior to blood tests). Unless of course you cannot maintain safe blood sugar levels going more than 12 hours, I would just consider what you ate at 5:30 your final meal. I would definitely drink water, though, unless they told you not to. Drink some water tonight. As soon as you get up drink more water. I don't mean a tiny sip. I mean drink water. It will be much harder to get a blood draw if you are dehydrated. Quote Link to comment Share on other sites More sharing options...
SparklyUnicorn Posted November 15, 2016 Author Share Posted November 15, 2016 Oh I'll be fine. Like today I didn't eat until noon after not eating past 6 pm. Quote Link to comment Share on other sites More sharing options...
SparklyUnicorn Posted November 15, 2016 Author Share Posted November 15, 2016 She said I could drink black coffee. Might do that. 1 Quote Link to comment Share on other sites More sharing options...
Code Lyoko Posted November 15, 2016 Share Posted November 15, 2016 She said I could drink black coffee. Might do that. If they said that was fine then hey, why not? :) I would still drink some water, too. You don't want them having to dig around in your arm to get a vein. 1 Quote Link to comment Share on other sites More sharing options...
