About this study
Official title: Comparison of Capillary Blood Sampling Techniques for Blood Glucose Measurement in People With Diabetes: An Experimental Study
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Capillary Blood Sampling TechniquesOther
Also called Capillary Blood Glucose Measurement Procedures
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 is being measured
The primary outcome is the main question the study is designed to answer.
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
Measured: Day 1
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.
Measured: Day 1

Questions about this trial
What is this clinical trial studying?
An observational study of Diabetes Mellitus, run by Ordu University at 1 site in Turkey (Türkiye).
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 3 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Difference between blood glucose measurements obtained with and without finger squeezing (time frame: Day 1). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Jun 2026.
