How accurate is a hemoglobin A1c test in indicating hypoglycemia?

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 more

My A1c is 5.9 & cortisol after 8 am test 33.5, insulin 28.7. I always feel shaky after meals. Dr says I have reactive hypoglycemia are my test bad?

My A1c is 5.9 & cortisol after 8 am test 33.5, insulin 28.7. I always feel shaky after meals. Dr says I have reactive hypoglycemia are my test bad?

Needs evaluation: The hba1c is mildly high and could indicate pre-diabetes. You need a fasting glucose and lipid profile to see more. The cortisol level appears high, you need to do an overnight Dexamethasone suppression test to evaluate. Most people who feel shaky after meals do not have low sugars causing it. You should check your sugar with a glucose monitor when you have symptoms. ...Read more

How precise is hemoglobin A1c with indicating hypoglycemia?

How precise is hemoglobin A1c with indicating hypoglycemia?

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

More I read about hypoglycemia more confused I get. If I miss bkf AND lunch I feel weak + hands shake, no other sx. A1c and 12h fasting gluc normal.

Most of it is bunk: Miss a few meals and your body will produce epinephrine to keep your blood sugar normal. That's why you shake. Please forgive me -- if you're so worried about "hypoglycemia", please adopt more sensible eating habits. Think about getting back into heavy-duty fitness. Almost everythingyou read about "hypoglycemia" apart from diabetes is rubbish. Best wishes. ...Read more

Fasting glucose 36mg/dl w/ fainting spells, after meal 82mg/dl, A1c 5.5 (math err?). Can a 8mm adrenal cyst cause hypoglycemia? Also-abd pain, acnes.

Fasting glucose 36mg/dl w/ fainting spells, after meal 82mg/dl, A1c 5.5 (math err?). Can a 8mm adrenal cyst cause hypoglycemia? Also-abd pain, acnes.

You don't: Have hypoglycemia after meals, as it's not a disease and doesn't exist in the absense of diabetes medication, cancer, end-stage liver or kidney disease, GI surgery, etc. If it's a finger-stick it's not accurate in that range. Your adrenal cyst is benign and has nothing to do with your complaints. Cyst should be followed over time. Glucose should be ignored ; it's a natural response to your obesity. ...Read more

What's a normal score on the A1c diabetes test?

Less than 6.0: This is a test of the chronic level of blood sugar and is useful to monitor the effectiveness of diabetic treatment. You should, if you are a diabetic, endea vor to get this below 7.0 and even lower if possible. The higher numbers show an increased risk of rather bad complications of diabetes. ...Read more

Could taking thiazide affect your A1c test results?

In a way, yes: Diazide worsens control of diabetes and may raise blood sugar level and indirectly raise a1c levels. The drug diazide does not directly affect the assay for a1c. See this site for more information on side effects of diazide.

My hb A1c test result shows 7. What exactly it means?

My hb A1c test result shows 7. What exactly it means?

Hb A1c test: A1c measures % of hemoglobin in blood which has glucose (blood sugar) attached to it. Normal for someone without diabetes should be around 4% or less. 7% is considered good control with diabetes. Too high (8% or above) increases risk of complications. If test was done for screening (not already on treatment for diabetes), your diabetes may be controllable with strict lifestyle changes. Good luck! ...Read more

Had my A1C checkefd about a year ago it was 7.2. I just did a home test and it is now 6.1 is that better?

Depends: An Aic level of 7.2 means that you are diabetic. Have you been on treatment for diabetes? If you were extremely compliant with the treatment, it is possible that your A1c level is 6.1 and that would be good. However, home tests are not as accurate as lab tests. If you have not been under treatment, you should consult your doctor at the earliest. ...Read more

A1C is accurate: However it measures average serum glucose over a 3 month period. An A1C of 5.8% equals an average glucose of about 115-120. Your meter may not be far off. ...Read more

Should I discontinue dmt2 med since my A1c is 6.5 and return in 3 months to test it again as experiment? Just die & exercise. I'm tired of taking med.

Not recommended: Don't stop any meds without talking to your doctor first. I know you are on metformin and onglyza (saxagliptin). At this point, I recommend continuing metformin but if you want to stop something, stop the Onglyza (saxagliptin) instead. Please see your doctor to discuss this before doing anything. Good luck. ...Read more

What is A1c test?

What is A1c test?

Glycosylated protein: Glycosylated hemoglobin A1c is a type of protein in your blood that is formed in the presence of sugar. Non-enzymatic glycation of the hemoglobin protien, thus higher sugar/glucose over time will cause higher level of hemoglobina1c. Docs order this test to assess the average/approximate level of sugar in blood over several months (3 or so), thus level of diabetes control.
Consult doc.
Good luck. ...Read more

On a routine test they told me I have an elevated A1c of 5.7, what does it mean?

A1C: A1C is a way to measure the average blood sugar over a 3 -4 month period of time. This is a measure of the sugar attached to the red blood cells. This means that your blood sugar is running too high and you need to start paying attention to your diet. You should also have your doctor measure a fasting insulin level. ...Read more

Do you fast for a hemoglobin A1c test?

Short answer: The test measures indirectly measures glucose control over the preceding 6-8 weeks. It does not measure sugar directly; therefore I would believe it not to be necessary to fast prior to the test. However, the best way to answer this question is to call the lab where you go to have the blood drawn and ask them directly whether you need to fast for the test. ...Read more

What can cause a high hemoglobin A1c test?

Poor sugar control: Hemoglobin A1c measures average blood sugar over approximately the past 3 months. It is the measure of how much hemoglobin is attached to sugar molecules in the blood. Sugar in your blood binds to the hemoglobin of the red blood cell and stays there throughout the cell's lifetime (120 days). At high levels of blood sugar, more reacts w/ the hemoglobin, causing an elevated hemoglobin a1c. ...Read more

Hemaglobin A1c is 19.8 on a home test what does this mean?

High sugar or wrong: Hemoglobin a1c show average daily glucose levels over 3 months. Hemoglobin in red blood cells change when exposed to glucose. The cells are counted to determine a level. Diabetes with a hba1c of 7 or less (average glucose <120 daily) is well-controlled. A 19.8 test result may be wrong or glucose levels are dangerous. See your doctor asap to get reliable results and begin appropriate treatment. ...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

Is the A1c test for diabetes accurate?

Is the A1c test for diabetes accurate?

Yes, it is.: The HgbA1C is a measure reflective of your degree of diabetic control in the long term. It essentially represents a three month average of your fingersticks, as if you took a fingerstick every minute, night and day, eating and fasting, for three months straight and then averaged them all. Technically, it's the percentage of red blood cells that have glucose attached to them. ...Read more
