Are random blood sugar test for glucose accurate for diagnosing diabetes?

Are random blood sugar test for glucose accurate for diagnosing diabetes?

Not ideal: There are multiple tests for diabetes but preferred are fasting glucose and hemoglobin A1c levels. Generally, these are tested on two separate occasions to confirm the diagnosis unless the numbers are way out of range. Non-fasting glucose with symptoms suggestive of diabetes can be reliable. Take care. ...Read more

The body naturally tightly regulates blood glucose levels as a part of metabolic homeostasis. Glucose is the primary source of energy for the body's cells, and blood lipids (in the form of fats and oils) are primarily ...Read more

Does psa blood test need fasting?

Does psa blood test need fasting?

No. For most blood: fasting is not needed & commonly misleading, though promoted. Optimal PSA value <1.0 ng/dL, though called normal up to 4.0 ng/mL. At 1.3 ng/ml (Avodart Trial; most thorough done to date) prostate size, by ultrasound, has doubled young healthy values. If PSA < 1.0, prostate cancer extremely rare. If elevated, consider https://www.accureference.com "Prostate Health Index" test for better guidance. ...Read more

Can Fasting Blood Sugar (FBS) be used for short-term monitoring of blood sugar level?

Can Fasting Blood Sugar (FBS) be used for short-term monitoring of blood sugar level?

FBS: I presume you have type 1 diabetes given your age. My apologies if your doctor has said you have type 2 diabetes and he is correct. Very unlikely unless you are substantially overweight. You should check your blood sugar almost all day if you have type 1 diabetes. There is excellent safe equipment for continuous blood sugar control. Can you please give me some more information about your diabetes. ...Read more

Which test is more reliable for monitoring diabetes: a blood sugar test or urine sugar test?

Which test is more reliable for monitoring diabetes: a blood sugar test or urine sugar test?

Bllod sugar: Glucose appears in urine only when blood sugar is greater than (debate) 180-220. Would like to aim for sugars 80-150 for good control. So can still be in 150-180 range, chronically, and still be in less than ideal control without any sugar appearing in urine. ...Read more

Results from 2hr oggt: blood draws: 1/2 hr=230; 1hr=292; 2hr=250 blood tests are negative for diabetes. Is this glucose intolerance or insulin ?

Results from 2hr oggt:
blood draws: 1/2 hr=230; 1hr=292; 2hr=250
blood tests are negative for diabetes.
Is this glucose intolerance or insulin ?

Diabetes: This is consistent with diabetes. The 2 hour after challenge should be < 140. If 140-199, that's prediabetes. I'm not sure what you mean by "blood tests negative for diabetes." go back to your doctor and ask for a test called a1c. This will confirm and tell you the severity of the diabetes. ...Read more

Recently blood glucose levels for non fasting males?

Recently blood glucose levels for non fasting males?

Normal fasting: 65-105 when drawn out of a vein while fasting. Various authorities have different "normal" levels. There are, however, no exact cut-offs, it's all a continuium. Finger sticks are not accurate enough for diagnosis. Two hour post meal should be less than 130-140, and any glucose >200 at any time suggests diabetes. An a1c >6% is also suggestive and needs further evaluation. See diabetes.Org for info. ...Read more
