Study summary

This study aimed to evaluate the effects of different capillary blood sampling techniques on blood glucose measurement results in people with diabetes. Blood glucose measurements obtained from the first and second capillary blood drops after antiseptic application were compared. In addition, measurements obtained with and without finger squeezing were evaluated. The findings may contribute to improving standardization in capillary blood glucose monitoring procedures and reducing unnecessary repeated finger punctures in clinical practice.

Read the detailed description

This methodological and experimental study evaluated whether different capillary blood sampling techniques influence blood glucose measurement results in people with diabetes. The study compared glucose measurements obtained from the first and second capillary blood drops and also evaluated measurements performed with and without finger squeezing under standardized clinical conditions. The findings are expected to contribute to the standardization of capillary blood glucose monitoring procedures and improve clinical practice by reducing unnecessary repeated finger punctures and enhancing participant comfort.

Interventions

  • OtherCapillary Blood Sampling Techniques

    Blood glucose measurements obtained from the first and second capillary blood drops and measurements performed with and without finger squeezing were compared using the same glucometer device under standardized clinical conditions.

What researchers measure

Primary outcomes

  1. Difference between blood glucose measurements obtained with and without finger squeezing

    Comparison of blood glucose values obtained from capillary blood samples collected with and without finger squeezing. Blood glucose measurements were obtained consecutively during a single study visit (Day 1), first from a capillary blood sample collected without finger squeezing and subsequently from a capillary blood sample collected with finger squeezing during the same blood sampling and measurement session

    Time frame: Day 1

  2. Difference between blood glucose values obtained from the first and second capillary blood drops following antiseptic application

    Comparison of blood glucose values obtained from the first and second capillary blood drops after antiseptic application. The first and second blood drop measurements were obtained consecutively during the same capillary blood sampling and measurement session.

    Time frame: Day 1
