Glucose; blood, reagent strip

CPT4 code

Name of the Procedure:

Glucose; Blood, Reagent Strip

  • Common name: Blood Glucose Test
  • Technical term: Capillary Blood Glucose Testing


A blood glucose test using a reagent strip involves pricking the finger to obtain a drop of blood, which is then placed on a strip that measures the blood sugar level. This simple and quick test is often conducted at home or in a medical setting and provides immediate results.


The purpose of this procedure is to monitor blood sugar levels. It is crucial for managing diabetes, assessing the effectiveness of diabetes treatment, and screening for potential blood sugar issues.


  • Symptoms of high blood sugar (hyperglycemia) such as excessive thirst, frequent urination, and fatigue.
  • Symptoms of low blood sugar (hypoglycemia) such as sweating, trembling, and confusion.
  • Known diagnosis of diabetes or pre-diabetes.
  • Monitoring blood glucose levels in individuals taking insulin or other glucose-lowering medications.


  • No specific preparation is usually required, but follow any instructions given by the healthcare provider.
  • Depending on the purpose of the test, fasting might be necessary.
  • Ensure hands are clean to avoid contamination of the blood sample.

Procedure Description

  1. Cleanse the fingertip with an alcohol swab.
  2. Use a lancet to prick the fingertip.
  3. Squeeze the finger gently to obtain a drop of blood.
  4. Place the drop of blood on the reagent strip.
  5. Insert the strip into a glucose meter which reads and displays the blood glucose level.
  6. Properly dispose of the lancet and strip.

No anesthesia or sedation is required for this simple procedure.


The entire procedure takes approximately 1-2 minutes.


  • Home
  • Outpatient clinic
  • Hospital or any healthcare facility


Typically performed by the patient themselves, a family member, or a nurse.

Risks and Complications

  • Minor pain or discomfort from the finger prick.
  • Slight risk of infection at the puncture site if proper hygiene is not maintained.


  • Provides immediate blood glucose level readings.
  • Essential for managing blood sugar levels in diabetic patients.
  • Helps in making timely decisions regarding diet, medication, and other treatments.


  • No recovery time is needed; normal activities can be resumed immediately.
  • Keep the finger prick site clean and covered if necessary.


  • Laboratory blood glucose testing, which is more comprehensive but takes longer to get results.
  • Continuous glucose monitoring systems, which provide ongoing glucose readings but are more expensive and require more complex technology.

Patient Experience

  • May feel a slight pinch or discomfort during the finger prick.
  • Immediate feedback on blood sugar levels, aiding in quick decision-making regarding diabetes management.
  • Pain management typically involves little more than proper technique and minimizing the frequency of finger pricks by rotating sites.
