Can a diabetes test be falsely negative?

The test you had would have been a fasting blood sugar level.  It does not come back as a positive or negative, but as a number indicating the level of sugar in your blood at the time.  You could always have the test repeated if you are worried, but I would discuss the result with the doctor first and see if your results were on the borderline of being high.  Most of your symptoms could be related to other things.  Is your diet healthy?  You could be very thirsty because your diet is high in sugar or salt, drinking more will lead to urinating more.  Maybe you are excessively hungry because your diet is not containing the right foods - do you eat a lot of refined carbohydrates like white bread, cakes, biscuits, sugar, if so you may need to change to whole grain and low GI carbohydrates which will make you feel more full.  Protein will also help.  You could be tired due to a poor diet as well.  And the irritability could be related to your diet or lifestyle.  Do you exercise enough?  You may need to have your eyes checked to make sure you don't need glasses.   I am only speculating here, but if you fit the description you may just need to look at your lifestyle and change a few things to feel 100% better.  Good luck!!

You should contact your family practitioner.  They will probably take some blood tests and check for diabetes.  You may have a problem with you thyroid, too.  I wouldn't wait.  Make your appointment tomorrow!  Be sure to FAST (not eat or drink anything) after midnight tonight.  They need an accurate test and fasting is the best way to get the best reading.  Call and tell the receptionist you need to see the doctor immediately

I think this would be considered as a negative test, talk to the doctor who ordered this test for you, good luck

It depends on a lot of things, such as if you were just near it or if you were sitting in a cloud of it, your weight, how much water you drink, whether you used drugs regularly previously, etc. I wouldn't worry about it too much though. Just drink a lot of water between now and the test and you should be fine. Also, depending on how negligible the results are to your test, they might assume something like that has happened or that there was an error and retest you anyways.

The gum has sweeteners in it instead of the sugar, so yes it is said to affect the results. Its best to have this tests in the morning, so you can fast over night.

ONLY a Doctor can help you with this. You should get an appointment set up so that you can go through testing to make sure that you don't have the developing stages of diabetes yourself. Maybe this site will answer more questions for you though.\n\nhttp://www.diabetes.com/

I don't think so; you need a blood sample to test its sugar content.\n\nThere are some new testers that use very little blood, but they still use a sample.

Yes, it is possible to be pregnant and have a negative home pregnancy test.  The test works by detecting HCG in your urine that you produce when you are pregnant.  You CAN be pregnant and not have enough HCG to turn one positive.  If you really want to know, go to your doctor and ask for a Beta Quantitative Analysis, which is the definitive blood test for pregnancy.

Sounds to me like a doctor has been trying to scare you.   Your numbers are fine.   It makes me crazy to see people worried about varying between 80-130.   This tells me that SOMEone has been spooking them about diabetes.   Yes, diabetes is a big problem in our country, but it's also big business.   The profits involved in the testing devices and medication is tremendous.    Some companies will give you a free tester because you will then use their products (via prescription) for the rest of your life, and may not need them.\n\nTrue diabetics have blood sugars like mine, 400s up, or like my cousins, which go from 30 - 400 in one day.   It is irritating as heck to hear people fretting about their blood sugar going up to 130  (usually after eating a chocolate cake).    A doctor or someone is telling them they are potential diabetics, instead of guiding them toward more healthy eating habits.    I have seen this too often lately, and hope people will be responsible and get a second opinion before getting treatment for a disease they don't have.   \n\nGood luck to you!!!!

It does sound very suspicious for diabetes.  Have you had a sugar tolerance test?  Ask for one.  If it comes out normal, it could be a result of poor diet causing fluctuating levels of sugar (instead of a problem with your body).  \n\nAs a teenager, I had similar problems, the buzzing and tingling would come right before I fainted.  Turns out, my diet had way too much sugar and carbs and I went too long in between meals.  If all tests continue to be normal, examine your diet.

I'm sure you already know that Hemoglobin A1c is a used as measure to see how well a person is keeping his or her diabetes under control.  However, if there has been a recent change in diet or treatment, the A1c may not be an accurate measurement of diabetic control.\n\n"Glycated hemoglobin measurement is not appropriate where there has been a recent change in diet or treatment within 6 weeks. Likewise the test assumes a normal red blood cell aging process and mix of hemoglobin subtypes (predominantly HbA in normal adults). Hence people with recent blood loss or hemolytic anemia, or hemoglobinopathy such as sickle cell disease are not suitable for this test. The alternative fructosamine test may be used in these circumstances and it similarly reflects an average of blood glucose levels over the preceding 2 to 3 weeks."

You could be anemic or other possible ailments. Whether or not you had sugar or not that day is irrelevant if you have diabetes. Go see your doctor for a check-up. Good luck

This depends on the testing procedure used.  The "quick" tests are prone to this sort of error.  They're the ones that are usually used for screening: making sure the urine is negative, so to speak.  In most drug testing paradigms, however, the ones that do not test negative on the quick screen are subjected to GCMS (Gas Chromatography, Mass Spectrometry) which is not at all prone to such errors.  Pseudoephedrine, which I presume is what you mean, will not fool GCMS.  The only thing that can is Vick's Inhaler.  Even that's something that can be sorted out, however.  On the whole, for tests subjected to the GCMS testing, there is still a volume of the urine that remains after testing.  You can request that it be subjected to resolving the D/L isomerization.  The Vicks inhaler is one; amphetamine is the other.\n\nLemon Grass?  It's not an issue here.  Vicks Inhaler is the only thing out there that is an issue, other than some prescription medications and illegal substances.

There are a few things that can cause a false positive:\n· Kidney infection and diabetes can cause you to test positive for cocaine.\nDesipramine and amantadine, prescribed to reduce cravings for cocaine, may cause false-positive results on urine tests for amphetamines.\n\nHave your doctor test your blood or hair samples.

yes it is possible. diabetes is when the body cannot regulate blood glucose level automatically.diabetes is hereditary although they do have a chance of not getting it. it would be a good thing to talk to your doctor and see what age you should get them tested at. people that continuously drink and drink more than normal is a sign that they may have diabetes. search through the link i have given you to find out more.

Pregnancy tests (even the ones done at home)  are rarely wrong if they are positive.  In rare cases, a hormonal imbalance can cause it to turn positive, however the urine tests are looking for a hormone that the body makes during pregnancy.  If it is there, the test will be positive.  If the hormone is not there, the test is negative.  Having irregular periods means that you probably have some kind of hormonal problems, but it does not mean that you cannot be pregnant.  If you have taken a pregnancy test and it is positive, GO TO THE DOCTOR!  Good Luck!
