How Accurate Is A Hemoglobin A1c Test In Indicating Hypoglycemia
Poor: Hba1c is fair at detecting chronically high bgs, but very poor at detecting low bgs. Fortunately, true low bgs are very rare and almost never sustained or recurrent. The sensation of "hypoglycemia", when related to sugar at all in people not treated with diabetes medications, is usually the normal response to low-ish sugars, which corrects them and keeps the body well. ...Read moreSee 1 more doctor answer
Less than 5.7: For people without diabetes, the normal range for the hemoglobin a1c test is between 4% and 5.6%. Hemoglobin a1c levels between 5.7% and 6.4% indicate increased risk of diabetes, and levels of 6.5% or higher indicate diabetes. Because out-of-control diabetes results in complications from the disease, the goal for people with diabetes is a hemoglobin a1c less than 7.0. ...Read more
According to quest diagnostics, fasting blood glucose should be 65-99. Mine is 127, is this too high for a diabetic?
Probably: Your lifestyle, compliance, diet, metabolic needs, and stress all play into how "tight" you can control your sugar. Ideally, your diabetic sugar control should approximate a non-diabetic's. You are allowed "bad days, " though--if your hgba1c is in-range, then an occasional abnl--even on test day--is ok. Talk w/your doctor. ...Read more
How accurate is A1C test? As compare to normal fasting blood suger test. What is the safe limit for A1C?
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

Hba1c test is within range but fasting blood sugar is 7.2. Can u get a true answer when checked after 12 hrs of eating?
Diabetes: Hi. Of the 4 means to diagnose diabetes, A1c and non-fasting (random) glucose are the least sensitive; glucose tolerance test and fasting glucose are the most sensitive. Your fasting serum glucose of 7.2 is frankly diagnostic of diabetes, and at the very least, impaired glucose tolerance. It should be repeated for confirmation. Fasting should only require 8 hours of not eating. Healthy lifestyle! ...Read more
Ignore it: The "gfr" given on lab sheets these days is a subscientific estimate of the rate at which water passes from blood into the the filtrate that will become urine. For a healthy person, the "gfr estimate" is not helpful. It ignores variability in body musculature, how much protein you have eaten recently, and other factors. ...Read moreSee 1 more doctor answer
How likely would be a false positive test result of tyrosinuria in metabolic urine screening after 12 hours fasting? If indeed pos., what is the cause
Rare entity if true: This is a rare condition that can be treated with a low phenylalanine/tyrosine diet. Blurry vision could be related but unlikely. High cholesterol and triglycerides are probably unrelated. Tyrosinuria is a genetic disease most common in french canadians. Repeat test if marginally abnormal. ...Read more
Not good at all: Hgb a1c should not be used to assess for hypoglycemic episodes or trends. It indicates only average blood sugars over months, and if there is concern or symptoms of hypoglycemia, then fingerstick blood sugar levels should be checked. Do some random ones, especially at night, and after high demand glucose things like exercise. Also check if having any symptoms - don't drive if you are low! ...Read more

Testing for H.pylori: H.Pylori status is checked with the intention of treating the infection to eradication, when found. If persistent or recurrent, please ask your doctor to prescribe a drug combination different than your initial regimen--your h.Pylori may be resistant to the first antibiotics used. Serology alerts us to past infection; stool testing, breath testing, stomach biopsy identify active bacteria. ...Read more
