The document provides comprehensive details on fasting blood glucose tests and random blood sugar tests, including their purposes, procedures, and nursing considerations. It outlines pre-test instructions, techniques for blood sampling, and how to interpret results based on established glucose level ranges. The importance of proper hand hygiene, patient identification, and post-procedure monitoring is emphasized throughout.
A test todetermine how much glucose (sugar) is in a blood
sample after an overnight fast.
The fasting blood glucose test is commonly used to detect
diabetes mellitus.
A blood sample taken in a lab, physician's office or
hospital.
The test is done in the morning, before the person has
eaten.

3.
Nursing considerations beforethe procedure
Instruct the patient/ client to do not eat or drink anything
other than water for at least 8 hours before the blood sample
is taken.
4.
Check doctor's order
Reviewthe patient’s medical history for diabetes type, medications, and/or
anticoagulant therapy.
Determine what type of test is required.
Gather equipment.
Perform hand hygiene.
Check room for additional precautions.
Nursing considerations before procedure
5.
Nursing considerations beforeprocedure
Introduce yourself to patient.
Confirm patient ID using two patient identifiers (e.g., name and date of birth).
Gain consent.
Check allergy band for any allergies.
Complete necessary focused assessments and/or vital signs and document on
MAR.
Ask the patient if she/he did eat or drink anything aside from water for 8 hours.
6.
Nursing considerations duringprocedure
Assess patient’s sites for skin puncture.
Select appropriate puncture site and perform skin puncture.
Clean the site with an alcohol and allow to dry.
Avoid fingers that are calloused, have broken skin, or are bruised.
Do not conataminate the site by touching it.
The droplet of blood needs to be large enough to cover the test pad
on the reagent strip.
7.
Nursing considerations afterprocedure
Dispose the used needles, cottons and gloves.
Wash hands.
Assist the patient to a comfortable position
Monitor patient's condition.
Review test results with the patient.
Document results according to agency policy.
Clean the areawith an antiseptic, like alcohol, to kill any germs.
Tie an elastic band around the upper arm, causing the veins to swell with blood.
Insert a sterile needle into a vein. Patient may feel slight to moderate pain when the needle
goes in, but it can reduce the pain by relaxing the arm.
The blood is then drawn into a tube attached to the needle.
After drawing blood, the healthcare professional removes the needle and places a bandage
over the puncture site.
Pressure will be applied to the puncture site for a few minutes to prevent bruising.

interpretation
World Health Organization(WHO) 2023
The normal range is 70 to 100 mg/dl
Level between 100 and 125 mg/dl are referred to as impaired fasting
glucose or pre-diabetes.
Diabetes is typically diagnosed when fasting blood glucose levels are
125 mg/dl or higher.
A random bloodsugar test is used to measure the
amount of glucose (sugar) in the blood without any
fasting conditions.
In RBS test, the blood is drawn randomly at any point of
time in a day.
It is done to diagnose pre-diabetes & diabetes or
diabetes mellitus.
what is random blood sugar test?
