Depends Severity &Tx: Unclear if asking before apparent or after recognized. One of the best tests, currently available clinically, for pre-dm is the NMR particle test lp-ir score. This measures lipoprotein particles, not glucose or Insulin resistance, as implied by the name. It relies on strong population correlations with lipoprotein behavior & Insulin resistance & can predict type ii dm 15-20 yrs before hba1c ?6.5%. ...Read more
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
Blood Glucose: The initial test for diabetes is a fasting (8-12 hours) blood glucose test - usually done by a finger prick check but can also be done by a blood draw. Typically fasting blood sugar values below 100 are considered non-diabetic, 100-126 pre-diabetes, and greater than 126 as defined by diabetes. A hgba1c blood test can then be done to monitor progress of treatment as this is a roughly 3 month avg. ...Read moreSee 1 more doctor answer
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

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
