Introduction

  • Ask the patient to wash their hands prior to the procedure with soap and water

Preparation 

  • Wash hands
  • Clean tray

  • Massage the finger from proximal to distal (to encourage blood flow)
  • When a second, large drop of blood accumulates, apply the golden part of the test strip (in the groove at the distal end) to the side of the drop of blood until the glucometer beeps
  • Place gauze over the puncture site and apply pressure until it has stopped bleeding
