Question 7

i have been having symptoms linked to diabetes even my doctor considered. i did take a fasting blood test and everything was fine. what is wrong?

Accepted Answer

Can't be sure.: In order to answer this question I would need to know your symptoms.  Clearly diabetes is not responsible.  Seems like your doc has probably ruled out a lot of other things as well.  You should probably continue your conversation with them regarding your concerns.

Question 8

very good afternoon doctors. i need to take a fasting blood test for glucose and for cholesterol. how many hours should i be on a fast before the blood test? what time the next day, morning or afternoon, is a good time to get the blood test?

Accepted Answer

: Take the test every morning before breakfast. This will give you an average result over time. Eating a late dinner, reading will be higher than eating an early dinner. In a prior question you asked why you had frequent nocturnal urination, yet stated you were not diabetic. High sugar levels and a1c may be the reason for your need to urinate throughout the night.

: No reason to interrupt the OTC preparation, as your blood lipid study should be taken after 12 hrs  of nocturnal fasting.
