Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Persons With Diabetes
Untrained subjects WITH Diabetes use Karajishi Contour BGMS (Blood Glucose Monitoring System).
Device: Subjects WITH Diabetes Use Karajishi Contour BGMS
Untrained subjects WITH diabetes use the Karajishi Contour BGMS (Blood Glucose Monitoring System). Subjects tested capillary fingerstick blood (and study staff tested subject fingerstick blood) using the Karajishi Contour BGMS. All BG results were compared to reference method results obtained with subject capillary plasma. Also, study staff tested subject venous blood and BG results were compared to reference method results obtained from subject venous plasma.
Experimental: Persons With and Without Diabetes
Untrained subjects WITH/WITHOUT Diabetes use Karajishi Contour BGMS (Blood Glucose Monitoring System).
Device: Subjects WITH/WITHOUT Diabetes Use Karajishi Contour BGMS
Untrained subjects WITH and WITHOUT diabetes use Karajishi Contour BGMS (Blood Glucose Monitoring System). Subjects tested capillary fingerstick blood (and study staff tested subject fingerstick blood) using the Karajishi Contour BGMS. All BG results were compared to reference method results obtained with subject capillary plasma. Also, study staff tested subject venous blood and BG results were compared to reference method results obtained from subject venous plasma.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Self-Test Fingerstick Blood Glucose (BG) Results Within +/- 15 mg/dL (<100 mg/dL) and Within +/- 15% (>=100 mg/dL) of Laboratory Glucose Method
Time Frame: 1 hour
Untrained subjects WITH diabetes (329) self-tested fingerstick blood using an investigational Blood Glucose Monitoring System (BGMS). BGMS results were compared with subject capillary plasma BG results obtained with a Yellow Springs Instrument (YSI) Analyzer. YSI Analyzer BG results were used to calculate the number of BGMS results within +/-15 mg/dL (<100 mg/dL YSI capillary plasma) and +/-15% (>=100 mg/dL YSI capillary plasma).
1 hour

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of Venous Blood Glucose (BG) Results Within +/- 15 mg/dL (<100 mg/dL) and Within +/- 15% (>=100 mg/dL) of Laboratory Glucose Method
Time Frame: 1 hour
Study staff tested venous blood of subjects WITH diabetes (329) using an investigational Blood Glucose Monitoring System (BGMS).

Time Frame: 1 hour
Study staff obtained and tested subject (WITH and WITHOUT diabetes) fingerstick blood using an investigational Blood Glucose Monitoring System (BGMS).
