Test For Insulin
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 moreSee 1 more doctor answer
Different tests: Insulin & glucose are 2 different ways to measure diabetes. Insulin is produced by pancreas to keep sugars under control. We measure glucose to see how well sugars are controlled. We can measure Insulin to determine how much effort pancreas is making to control sugars. Think of glucose as speedometer & Insulin as tachometer (hgba1c is avg trip speed - ask a car nut if this doesn't make sense). ...Read more
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 moreSee 1 more doctor answer
Recently bloodwork for fasting insulin. How is this different that a glucose tolerance test or a fasting glucose test?

Took two, 3 hour glucose tolerance /insulin tests, one test had low blood sugar AND second test had high insulin both in the 3rd hour. How to treat?
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 moreSee 1 more doctor answer
Tested positive for heroin twice w/swab test. Never used! should I ask for blood and/or urine test?
Exercise your rights: Get legal counsel first. If an unknown enemy has administered heroin to you so that you will lose your job, then you will test positive and are in serious danger. A swab result alone can be false positive cannot be used against you since it must be confirmed with a second test using a different chemical principle. However, some dunce may not know this. I am sorry this is happening to you. ...Read more
8 hours is typical: Some doctors recommend nothing but water for 12 hours, and suggest that you should avoid fatty meals for 24-48 hours prior. Some doctors no longer require fasting at all. It could be argued that fasting doesn't represent the amount of lipid that is typically present in the blood, so it is less useful to look at fasting measures. Others think the post meal measurements are misleading. 8 hrs is fine ...Read more
