Probably would be best if you check with your ordering physician to make sure that you understand what you need to do. This will make you avoid potentially abnormal results or the need for a repeat test later. ...Read more

No: The hemoglobin A1c is a measure of the amount of hemoglobin that is bound to glucose (blood sugar) in red blood cells. Red blood cells live about 120 days, so the A1c gives an idea of diabetic control over 3 months. Eating on the day of the test will make no difference. Be sure, though, that no other tests, such as fasting lipid panel or fasting chemistries, have been ordered along w a1c. ...Read moreSee 1 more doctor answer
No: Microalbuminuria is the presence of small amounts of protein in the urine, usually too small to note on a dipstick test. A trace amount of protein can be normal, but usually there is none. The most common cause of m is diabetes mellitus; it usually indicates that the dm has started to affect your kidneys. Once this happens, take things more seriously: talk with your pcp and consider endocrinology. ...Read moreSee 1 more doctor answer
Tell the lab: Let the lab or office now so they can account for that when interpreting results or re-schedule that particular test for when you are fasting. Not all blood tests require you to be fasting but some will give false results if you are not fasting at least 6 hours. ...Read more

HGA1C: Is a 3 month average of you blood sugars a gives a n accurate average. It does not obviously account for highs and lows because these would balance out. A glycomark test added to the hga1c will tell you over the last 2 weeks any way how stable your sugars have been or how much they were swinging ...Read more
No! Fasting of?Value: Fasting for most issues not only of low value but often misleading. Ex.: people commonly told to fast before blood glucose test; yet Diabetes Mellitus=elevated blood glucose & glucose most commonly elevated after eating. Thus fasting glucose routinely misses Diabetes Mellitus. Fasting is promoted for only a few issues because how databases were done or because the values are calculated/estimated. ...Read moreSee 1 more doctor answer
Why jeopardize baby?: You could refuse it, but why? Having gestational diabetes could cause significant harm to you and/or your child. Simple dietary changes and/or meds could prevent that damage. There are other blood tests that can be done to assess for gestational diabetes, if you're reluctant to do the oral glucose challenge test. Ask your OB doc to refer you to an endocrine (or diabetes) clinic. ...Read more
I frequently urinate..May see urologist..I have no pain when i pee..Also, should I also get a test for diabetes? Do i need to fast?
Diabetes: Given your age this is most likely an enlarged prostate due to inflammation or infection. Your family physician can examine and diagnose this. If you are at risk for diabetes then yes this can be tested as well at your family medicine clinic. They may like you to be fasting but it is not 100% mandatory. ...Read more
I did a boold test and my hemoglobin ac1 is at 5.6 is that bad and how fast can it get to 5.7 pre diabetes?
5.6 is "normal": An a1c of 5.6 is considered normal. This test measures the "sugar coating" of your red blood cells. A value of 7.0 or higher means the average sugars are >140 and can cause damage to nerves, blood vessels, kidneys, etc. To keep the a1c down, focus on diet and exercise. Regular resistance exercise (weights, resistance bands, etc) have been shown to decrease sugars quite a bit! ...Read moreSee 1 more doctor answer

Had a plac test of 294. How fast should my doctor be moving on this. Normal bp, 170ch, normal trigl, no diabetes and no family history.
Not a standalone: The plac test by itself should not be used to determine risk; it should be used with other tests and factors, such as you mentioned, to determine your cardiovascular risk. That being said, it does appear that a value > 200 should prompt more aggressive staging for cvd. ...Read more
Do i need to fast for the 1hr glucose screening @24w pregnant? Are all pcos patients diagnosed with gestational diabetes? Took metformin until 13w.
No, but: Some doctors do have their patients fast for their 1hr glucola tests (my office does), but it is not necessary. No, not all patients with pcos will be diagnosed with gestational diabetes, but you do have a higher chance of developing gdm if you had pcos, and often an 'early' 1hr glucola screen will be done to see if the patient has pre-existing diabetes. ...Read moreSee 1 more doctor answer
What are the most common symptoms of diabetes and what’s the best test to do to confirm? Can endometriosis and diabetes be related?
Blood: 1st step is simply check the random blood sugar. Your random blood sugar requires a blood sample. Your random blood sugar should be between 70 and 120. If the blood sugar is higher than 120 (dependent upon how much higher), the next step would be a blood a1c test or a glucose tolerance test. ...Read more
Fast may not be good: Since your body has adapted to living with high-sugar state, rapid drop to normal range may cause relative hypoglycemia (dizziness, blurry vision, weakness, sweating, even passing out). Diet/exercise, and wt loss if obese, is always advised. I would consult doc and and nutritionist/diabetic educator and work out a plan than is safe and maintainable over time, a life-time. Consult doc. Good luck. ...Read more
Testing for diabetes: Hi. The tests for diabetes (fasting glucose, post-challenge glucose, 3-month average glucose, and random glucose) all have their strengths and weaknesses. A1c is an excellent test and vital to the modern management of diabetes; it's NOT the most sensitive diagnostic test, however. Fasting and post-challenge glucoses can both reveal more subtle abnormalities. Random glucose is a blunt instrument. ...Read more
Yes: Certainly sodas with sugar can raise one's blood sugar, at least temporarily. Even diet sodas can lead to changes from the caffeine, and stimulation of hormones in the GI tract when the taste buds sense something sweet. This is why patients are advised to avoid everything but water when coming in for fasting blood tests. Tests for glycated hemoglobin, or a1c, are not affected by food or drink. ...Read more
