What Is a Random Plasma Glucose Test?

The random plasma glucose test is a blood test that trial the amount of glucose in your blood at a random time, without regard to joined to you last ate.

Also called a casual plasma glucose test, the procedure measures blood glucose in milligrams per deciliter (mg/dl), a useful measurement when checking for diabetes.

When the Test Is Done

A doctor is maybe to order a random plasma glucose test in the back a person has signs or symptoms of diabetes, including:

Excessive thirst

Excessive urination

Fatigue

Weight loss

Increased hunger

Blurry vision

How Its Done

The random plasma glucose exam is done by drawing blood from a vein, later sending the blood sample to a lab for supervision.

In the lab, the sample is spun in a centrifuge to cut off the blood cells and platelets from the liquid portion of the blood, called the plasma. The battle of glucose is furthermore measured in the plasma.

How rapidly exam results are ready depends upon where the test is finished. If its done in a hospital, the results may be ready within an hour or two. If blood is drawn at a doctors office, along with sent to a laboratory, results may not be easy to reach to for a daylight or two.

What the Results Mean

People who dont have diabetes rarely have blood glucose concentrations on top of 140 mg/dl, even after eating.

A random plasma glucose test upshot of 200 mg/dl or well along in a person who with has signs or symptoms of diabetes usually means the person has diabetes.

However, the diagnosis is generally confirmed connected to a fasting plasma glucose test, an oral glucose tolerance test (OGTT), or a hemoglobin A1C test. (Diagnosis by A1C is now commonplace, past the OGTT is too cumbersome for patients and doctors in primary care.)
