MamaBearTeacher Posted November 25, 2015 Share Posted November 25, 2015 If a child has half a muffin immediately before a blood test for hypoglycaemia will it affect the results? If so, how? This is a child who does have a lot of sugar in his diet normally. Quote Link to comment Share on other sites More sharing options...
Roadrunner Posted November 25, 2015 Share Posted November 25, 2015 (edited) Some sugar will hit the blood stream right away, but the peak in sugar spike is usually one hour. In two hours the sugar should return to normal. I don't know how they test for hypoglycemia, but I would guess they would have the kid drink a sugary substance and test the body's response every hour. Did they not give you guidelines?

Katy Posted November 25, 2015 Share Posted November 25, 2015 Yes, because insulin will rise prior to the test, and when it rises it will stay higher than a fasting state for something like 12 hours minimum if I remember correctly. 1 Quote Link to comment Share on other sites More sharing options...
gardenmom5 Posted November 25, 2015 Share Posted November 25, 2015 (edited) yes - it will affect results. were you told this was a fasting test? he shouldn't have eaten anything for 12 hours beforehand. (they'll usually say "after midnight".) when you eat - your blood sugar level goes up proportional to the sugar content of the food, while it is digested. so, his results are going to be inaccurate. even when doing the glucose tolerance test - they give you very specific glucose drinks taken at specific intervals to determine tolerance. (and if you eat anything - the results are thrown out, and the test has to be redone.) I have sympathy - I have to do fasting blood work about every 10 weeks, and today was the day. dr's 'nurse' is really bad at draws, and after two failed attempts, I ended up at a lab with their phlebotomist. it was 1:30pm and I hadn't eating since dinner last night. I was very hungry. Edited November 25, 2015 by gardenmom5 Quote Link to comment Share on other sites More sharing options...
klmama Posted November 25, 2015 Share Posted November 25, 2015 Yes, it will affect results. Let the doctor know what happened and ask that it be included in his chart so that anyone looking at the info in the future will have the info.

MamaBearTeacher Posted November 25, 2015 Author Share Posted November 25, 2015 Thanks. I forgot to say that it was not a fasting blood test. If he does have hypoglycaemia is it likely to show a false negative?or a false positive if he doesn't have it? Quote Link to comment Share on other sites More sharing options...
jjeepa Posted November 25, 2015 Share Posted November 25, 2015 The test I was given to diagnosis my hypoglycemia is called a Glucose Tolerance Test, different than the Oral Glucose Tolerance Test given to test Diabetes 2, and it requires 4-6 hours of fasting. My doctor insisted on this test and informed me that it is the only definitive test for that condition. Here's more info about it from The Hypoglycemia Support Foundation - http://hypoglycemia.org/what-is-the-glucose-tolerance-test/. I do have hypoglycemia, but not diabetes, and would be happy to help in any way if your son is diagnosed with this condition. Quote Link to comment Share on other sites More sharing options...
MamaBearTeacher Posted November 25, 2015 Author Share Posted November 25, 2015 Thanks. The test she gave was not fasting at all. Just a plain blood test. Quote Link to comment Share on other sites More sharing options...
