Random Plasma Glucose
Blood Tests for Diabetes Diagnosis and Management: Random Plasma Glucose Test
Also known as: Casual plasma glucose; random blood sugar test.
What is it? The random plasma glucose test measures plasma, or blood, glucose levels. It is performed with a small blood draw taken at any time of the day (hence the name "random").
How is this test performed? The test consists of a simple blood draw, which is sent to your doctor's lab for analysis.
What do my results mean? A random plasma glucose test that is under 200 mg/dl (11.1 mmol/l) is considered acceptable.
What do abnormal results mean? Levels of 200 mg/dl (11.1 mmol/l) or higher, along with the presence of symptoms of diabetes (e.g., excessive thirst and/or urination, blurry vision, unexplained weight loss), indicate a diagnosis of diabetes. The ADA recommends that the diagnosis be confirmed with a subsequent retest on a different day. The retest should be an oral glucose tolerance test or the fasting plasma glucose test if possible.
Other conditions which may result in an elevated result include pancreatitis, Cushing's syndrome, liver or kidney disease, eclampsia, and other acute illnesses such as sepsis and myocardial infarction (heart attack).

One of the sets of questions was about their medications. A list of them was posted on the door to the den. The case nurse assumed...
