Blood Glucose Monitoring

Blood glucose monitoring is a method to assess glucose levels in the blood using a small drop of blood obtained from the finger or other sites and a reagent strip or glucose meter, and it is used to monitor conditions like diabetes, gestational diabetes, and hypoglycemia. The document outlines the necessary equipment, steps to perform blood glucose monitoring including obtaining the blood sample, applying it to the reagent strip or meter, and interpreting the results, as well as sources of error to avoid inaccurate readings.

 Blood glucose monitoring is a method of assessing the concentration of
glucose in the blood.
 Tests are performed rapidly and easily by using a reagent strip (e.g.
Glucostix) where a minute drop of capillary blood is obtained from the
client’s digits (finger or toe), earlobe or heel.
 On the condition where the patient has all the equipment this test can
be performed at home, office, hospitals, clinics and even when travelling.
Blood glucose tests detect blood glucose levels in people with the following
conditions:
 Diabetes Mellitus (Type 1, Type 2)
 Gestational diabetes
 Neonatal hypoglycemia and blank
 Diabetic Coma
 Reagent strips or test strip
 Clean Gloves
 Alcohol pads
 Lancets or lancing device
 Portable glucose meter
 Watch (with second hand)
 Pen and Logbook for documentation
1. Identify the patient by asking the patient to state his/her name. Also
check the client’s identification band. ( confirm patient’s identity using
two patient identifiers, based on the hospital protocol)
2. Explain the procedure to the patient or parents (if patient is a child)
to gain cooperation.
3. Wash hands and don clean gloves.
4. If glucometer is used, load the strip into the device beforehand.
5. Swab alcohol pad to the chosen puncture site. Use sterile/clean gauze to
dry it thoroughly. Piecing the skin with a wet skin (alcohol) allows the
chemical to pass through the outer layer of the skin thus, causing the
procedure more painful and uncomfortable
6. To collect a blood sample, position the lancet (pricking needle) at the
side of the site. To minimize pain and patient’s anxiety pierce the skin
sharply and briefly. This technique also increases blood flow. For better
results, some agencies are using a lancing device (mechanical blood-letting
device) wherein the lancets are simply loaded in the spring of the
equipment. (It’s like using a spring-loaded pen, once you click the button
the spring releases the lancet and immediately retracts it after piercing
the skin). However, be sure to load an unused lancet before using to
prevent spread of blood-transmitted diseases.
7. Don’t squeeze the puncture site to prevent diluting the sample with
fluids from tissues.
8. Cover the entire patch of strip with blood.
9. Place gauze over the punctured area and briefly apply pressure until the
bleeding stops. Ask the parents of a child to do this.
10. If using a reagent strip, leave the blood on the strip for 1 minute (60
seconds). And watch the color change on the strip while comparing it to
the standardized color chart of the product container.
11. If glucometer is used, simply follow the manufacturer’s instruction.
12. Apply an adhesive bandage once the bleeding on the puncture site has
stopped.
13. Remove gloves and record the resulting glucose level from the digital
display for glucometer or from the color of reagent strip to the
standardized chart.
1. Dropping a very small amount of blood
2. Inappropriate timing ( the test is usually performed before meals and at
bedtime, or whenever hypoglycemia or hyperglycemia occurs)
3. Squeezing the puncture site too hard allowing tissue fluids to mix with
the sample
4. Improper maintenance of glucometers (dust or blood accumulation on the
digital display)
