What is random blood sugar level?

Random blood sugar level refers to the measurement of glucose concentration in the bloodstream at any given time, regardless of when a person last ate. It is an important diagnostic tool used to screen for diabetes or monitor blood sugar levels in individuals with diabetes. By measuring the amount of glucose present in the blood, healthcare professionals can assess a person's glycemic control and determine if further testing or treatment is necessary.

What are the types of random blood sugar level?

There are primarily two types of random blood sugar level assessments:

Fasting Blood Sugar Test - A test performed after an individual has not consumed any food or drink (except water) for at least eight hours. This measurement provides a baseline level of blood sugar and is typically conducted in the morning after an overnight fast.
Postprandial Blood Sugar Test - A test conducted after a person has eaten a meal. It measures the blood sugar level one to two hours after eating, providing insight into how the body processes glucose during digestion.

How to complete random blood sugar level

Completing a random blood sugar level test is a straightforward process that can be done with the following steps:

01
Ensure you have a glucose meter or access to a healthcare professional who can perform the test for you.
02
Wash your hands thoroughly with soap and warm water to ensure accuracy and reduce the risk of contamination.
03
Using a lancet, prick the side of your fingertip to obtain a small drop of blood.
04
Apply the blood sample to a test strip, following the instructions provided with your glucose meter.
05
Insert the test strip into the glucose meter and wait for the results to be displayed.
06
Record the blood sugar reading in a logbook or note it down for future reference or to share with your healthcare provider.

Questions & answers

FORMULAS : Average Plasma Blood Glucose (mg/dl) = (HbA1c * 35.6) - 77.3. Average Plasma Blood Glucose (mmol/L) = (HbA1c * 1.98) - 4.29. Average whole blood glucose = Plasma Blood Glucose / 1.12.
A blood sugar level less than 140 mg/dL (7.8 mmol/L) is normal. A reading of more than 200 mg/dL (11.1 mmol/L) after two hours means you have diabetes. A reading between 140 and 199 mg/dL (7.8 mmol/L and 11.0 mmol/L) means you have prediabetes.

Blood sugar (also called blood glucose) needs to be tightly controlled in the human body to minimise the risk of complications developing. Formula to calculate mmol/l from mg/dl: mmol/l = mg/dl / 18. Formula to calculate mg/dl from mmol/l: mg/dl = 18 × mmol/l.
Insert a test strip into your meter. Prick the side of your fingertip with the needle (lancet) provided with your test kit. Touch and hold the edge of the test strip to the drop of blood. The meter will display your blood sugar level on a screen after a few seconds.
