Where can I get a glucose-after-fasting 2-3 hour insulin test in the UK?

I am insulin-resistance (aka Syndrome X) and need to test for natural insulin levels; I had this test before but the clinic no longer exists and my GP doesn't have the results. I need my blood to be taken on an hourly basis for 2-3 hours after taking a measured amount of glucose. Glucose and INSULIN levels are then tested - in the previous test I had normal blood sugar levels, but 70+ insulin after 3 hrs, which is very high (normal range up to 17). I need to be treated with Meformin, but the standard GP fasting blood sugar level test is useless as it doesn't pick up the post-glucose very high insulin levels, so I can't get treatment. I'm already on a very low GI diet etc. but am struggling with weight - weight reduction would increase insulin sensitivity. I'd like this test preferably in London.

Go to your Dr, he will refer you to a laboratory and they will do the test, don't just go to a lab that advertises, they may not be very good, but an NHS lab is checked every week for quality and can only exist if there results are accurate.

Ask your GP to refer you to an endocrinologist at the hospital.

You can get test kits from boots for 20 pounds.
I have one and its incredibly accurate.
its the same type they use at the docs with the finger prick.

Its called accu check

I would recommend you go back to your doctor he is your best resource. Other good resources are your pharmacists, the walk-in clinics in your area or the hospital. Simply go to or call up either the clinics or hospital in and around your area and ask. They will have the answers you need and perhaps some you did not know you would need.

Take care....

this is an aspect of diabetes that i have heard almost nothing about except for a friend who is a very heavy drinker because he says he needs to keep his sugar levels due to over production of insulin;everything i have read in twenty five years fails to mention this as it may be an extemely rare problem probably treatable by the endocrinology clinic as it sounds like a problem originating in the pituatary's regulation of the pancreatic secretions
note that diabetes consultants are endocrinologists and you might find an answer in the influence of the thyroid gland on the pancreas
love to hear what you turn up as this is not in any of the books and you may need to go to a high level to find out

a lot of lloydds chemists do free glucose level testing so give it a go
