Blood test without fasting?!
Question: Blood test without fasting?
well I'd had breakfast 3 hours before but all I had was shredded wheat with rice milk and a boiled egg, and the tests were: thyroid, fsh,lh and other things similar to that which I can't remember

It depends what the test was for! Sugar and lipid profile tests are the classic ones requiring a fast, but they can still be interpreted if you have eaten.
GP for more years than I care to remember
Hey
The reason they prefer you not to eat is so that your food doesnt interfere with the test results. For example if they run full bloods then your sugar levels may be showing as high which would make them think you could have diabetes but as you had breakfast before the test that would be why the sugar was high, so basically the tests are coming back false or inaccurate.
Hope that helps
