A quick info on RBS test

A quick info on RBS test

Overview

Overview

PharmEasy Labs are on a mission to make diagnostic tests easily available to all people in India. That is why these Labs are present in all major cities and towns of India. Not only that, but the test price is also super affordable thanks to the discounts that are offered on all tests. With home sample collection and email delivery of reports, you wouldn't even have to step out of your house.

You can also be assured of the reports' accuracy. Because machines using the latest technology are utilized, there will not be any errors. Moreover, highly experienced technicians and pathologists work in the Labs. Diabetes is a common health disorder in India, and hence PharmEasy Labs offers RBS test at competitive rates.

The RBS test can give your doctor a clear picture of how much glucose is present in your blood. High levels of glucose indicate a problem with insulin. Either there isn't enough insulin in your system, or your cells are not responding to the insulin. This helps the doctor decide whether further glucose tests are necessary to pinpoint the type of diabetes.

Though RBS is a very important test that gives an accurate reading of blood sugar levels at any time of the day, doctors usually prescribe it only to see if you have diabetes but not for pre-diabetes. This is because our blood sugar levels fluctuate throughout the day, and close after a meal, the levels are naturally a little higher than usual. If an RBS test is done soon after a meal, it may show elevated glucose levels that appear to be in the pre-diabetes range but are actually quite normal because, after a while, the levels would drop.  The RBS test is also very useful in monitoring diabetes.

Test Necessity

Test Necessity

Your doctor will recommend this test if you have a predisposition towards diabetes, for example, if you have a family history of diabetes, had gestational diabetes or have high blood pressure or a high body mass index.

The RBS also becomes necessary when you start showing the symptoms of diabetes, such as-

  • Frequent need to urinate
  • A constant feeling of thirst
  • Exhaustion
  • A vision that is blurry
  • Persistent hunger
  • A rapid change in weight

Your doctor will also want you to undergo the RBS test at regular intervals if you have diabetes to see if the medication dosage needs to be altered.

Test Preparation

Test Preparation

Since the RBS test is meant to check a person's blood sugar levels randomly, it requires no preparation at all. You can eat, drink fluids and water as you normally do. Don't drink more water than normal because too much water may affect your blood sugar readings.

During the RBS Test

Since the RBS test is a blood test, you can expect a phlebotomist from PharmEasy Labs to come to your home on the day and at the time that you choose. A vein finder will be used to pinpoint the correct vein and with clean new needles and syringes, a small volume of blood will be drawn. The sample will then be sent to the labs.

Test Result Interpretation

Test Result Interpretation

The Random Blood Sugar tests the level of glucose in your blood. This helps in determining if your body is producing enough insulin for the optimal functioning of all organs. A Random Blood Glucose value higher than normal and below 200mg/dl puts you at the risk of developing diabetes.

This would call for frequent tests as suggested by your doctor and specific changes in your daily lifestyle to prevent your glucose levels from rising any further.
