Bloodtest negative, but what does it tell?

John - 21 Dec 2005 10:42 GMT Dear all,
I have been tested for diabetes negatively. My family doctor thought I had diabetes, because of my decreased sight (from 0 for years to -1), bad skin condition, and tiredness problems. However, he prescribed a blood test sober (no eating in the morning, no sugar etc.) I have read that there still could very well be a possibility of diabetes mellitus type 2, because I was not tested after sugar intake.
Can anyone here tell me if I should undergo another blood test this time? My facility doctor now things there is nothing wrong. But I still have these symptoms.
Faithfully, John

also telling us that the test was negative is meaningless. The test will have actual BG readings, without those numbers what you are being told is worthless. Many of us have found that GPs have frequently told people that they were not diabetic when in fact they were and they could have found this out if the doctor had actually given them the numbers from the tests. This happens because the GPs have not kept up with current diagnostic criteria and current studies.

Good luck and DO something.

Loretta Eisenberg - 21 Dec 2005 14:33 GMT Do you know anyone that has diabetes . If you do and they have a glucose monitor perhaps you could test on there , one hour after a meal and two hours after a meal.
I believe you need to see a specialist. one test doesnt do it.

Annette - 21 Dec 2005 13:16 GMT > Dear all, > [quoted text clipped - 11 lines] > Faithfully, > John Hi there John,
I agree with Mack. It is not clear whether the doctor is not up with the current criterea or if you really do not have any indication of diabetes in your tests.
Either way, what else has he investigated to discover just what is causing your symptoms? Obviously, *something* is wrong, because you don't feel well. Do go back and see him, and ask him what other tests has he in mind to try and find out what is wrong with your health. While you are there, ask him for a copy of the results of the last blood test, for your personal file.
If he says you don't need a copy,. just say, "Yes, I understand, but I would still like a copy for future reference". In short, insist on one. If he reckons he does not think you need any further testing, then it may be a good idea to find a new doctorif you can, ie, one who takes you and your healthy more seriously. Don't risk your health with an old-fashioned "trust me" kind of doctor, no matter how long he's known you or how much you like him otherwise. If you have some difficulty in doing that, then insist that he does not just let it go, but looks into it further.
It is always a good idea to ask for and keep your own file of the lab results or any other tests you have done.
1. Even if you don't understand what they mean, you can look them up and learn for yourself what they mean and might indicate. Many a modern doctor respects a patient who knows what he's talking about.
2. It is always a good idea to understand exactly what is going on inside your body - simply because it IS *your* body! The internet has made it possible to learn about the things that matter to you.
3. Doctors do lose test results, or files, or can leave their practice, or move away, or you might move elsewhere, and other simple mishaps that end up leaving you without a record of your previous medical hisory over a long period of time. Even simply that long passage of time can cause difficulties, you can't just rely on your memory. At the very least they provide a history for any future medical investigations and a reliable reference. A kind of bench mark. Doctors do NOT rely on your anecdotal reports. They need accurate and precise medically provided information.
4. It's also a good idea to keep a record of any meds you have been prescribed as you go along, and similar records. Keep all these records, including x-rays, radiologists or other specialists letters and reports, and so on - ask for copies!
It may seem a bit of trouble, but a simple manilla folder where you can store such things may prove extremely helpful in the future.
All the best,
Annette

FOLDER?? I've got 1/2 a file drawer (getting on toward 3/4) of medical records! I've also written up a sort of "medical resume", summarizing everything that I've got now, all my meds & supps & other treatments, with a bit of history, & names & phone #s of all my current medics. It's several pages (in readable size type) -- impressed the hell out of a new doctor I went to (yet another specialist). bj

[quoted text clipped - 10 lines] > specialist). > bj Well, bj, how much info you keep and how much space it takes is your business! :-0 If you need that much storage space, then you need it. I have one of those folding cardboard files, but I only started keeping records in the last 5 yrs. I keep all my x-rays, in their envelopes, under the bed, to keep them flat and safe. But I started with an ordinary folder, it's a good way to start keeping one's medical history all together, making it easy to locate and take with you when needed. These days I more often just extract those that are relevant to the condition for that particular visit.
As for specialists, I've discovered that they really appreciate a well kept set of records and x-rays, reports and so on. It saves them from repeating some of them, for purposes of elimination, and from wasting time on "dead ends". It gives a really good medical history for consideration, and may even inspire the specialist to see some connections or links in the past that can reveal a clue to your current condition and effective treatment(s).
It also backs up the information you disclose to the doctor, as being accurate and informed, making you a credible and knowledgable patient.
I once left a doctor because when I showed him my recent copies of the report and other test results regarding my heart's state of health, he tossed them aside, saying "All that means nothing to me!" in a most dismissive tone. This was NOT a man I wanted to have taking care of me! I would rather have a doctor who is well trained and knowledgable than one who thinks he is prescient.

To understand what is happening, it might help to read http://www.geocities.com/lottadata4u/misdiagnosis.htm There's a lot there, but it explains why so many people with diabetes are not diagnosed until they already have serious long-standing complications.
The good news is that with or without a diagnosis, you can do a lot to improve the situation.
Step 1 is to read http://www.alt-support-diabetes.org/newlydiagnosed.htm and get your self a blood sugar meter and strips at your local pharmacy. The store brand ones are cheaper and just as good as the expensive ones. I had the same problem you had and it was 2 years until I could find a doctor who would diagnose me based on my very high post-meal readings.
But once I got a meter and saw that I was routinely over 200 mg/dl after meals, I knew I was diabetic and did not wait for exterior confirmation.
Once you have a meter you can start lowering your carbohydrate intake until you reach a level where your blood sugar is normal or near normal. If you do this, you should find that many symptoms improve.
If you can't get your blood sugar under control via dietary control, it is time to take your test results to a doctor who will take them seriously.
My own experience has been that this might NOT be an endocrinologist. Most endos seem to treat mostly Type 1s and severe Type 2s and they can be very dismissive of people who "only" have post-meal blood sugars in the 200s if their Hba1c results aren't over 7%. That was my experience. Two endos have told me they don't really know how to treat patients who don't have A1cs in the 8% range or more (the level where your fasting blood sugar is near 200 and post meal numbers can be 300 or more.)
A good, up-to-date family doctor can be of better use, in this case. At least that has been my experience (with two family doctors.)

Go to an endo soon and explain your concerns. I'm hoping you'll go to one of the smart ones. some of them are truly pathetic and may miss a DX as much as a GP. Good luck.

Michelle - 22 Dec 2005 02:02 GMT John,
You are asking some VERY smart questions. I assume (correctly, I hope) that your doctor did a fasting blood sugar test.
Due to a family history of diabetes, when I started feeling tired all of the time and hungry most of the time, I suspected diabetes. Testing showed that my fasting sugars are perfectly normal. However, after I eat certain foods--foods that I ate everyday like white bread--my one hour sugar spikes at about 175--definitely not normal. By the 2 hour mark my sugars are almost always okay again. The point being that fasting sugars are not the whole story by any means.
You definitely need to find a doctor willing to investigate this further. Your fasting test did not rule out the possibility of diabetes.
Michelle
