Våpen og intervensjoner

Deltakergruppe / Arm
Intervensjon / Behandling
Eksperimentell: Persons With Diabetes
Untrained subjects WITH Diabetes use Karajishi Contour BGMS (Blood Glucose Monitoring System).
Enhet: 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.
Eksperimentell: Persons With and Without Diabetes
Untrained subjects WITH/WITHOUT Diabetes use Karajishi Contour BGMS (Blood Glucose Monitoring System).
Enhet: 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.

Hva måler studien?

Primære resultatmål

Resultatmål
Tiltaksbeskrivelse
Tidsramme
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
Tidsramme: 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).

Tidsramme: 1 hour
Study staff tested venous blood of subjects WITH diabetes (329) using an investigational Blood Glucose Monitoring System (BGMS). Venous BGMS results were compared with subject venous plasma BG results obtained with a Yellow Springs Instrument (YSI) Analyzer.

Tidsramme: 1 hour
Study staff obtained and tested subject (329 WITH diabetes) 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 capillary plasma 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
Number of Responses From Persons With Diabetes That Either 'Strongly Agree' or 'Agree' or Are 'Neutral' With Questionnaire Statements
Tidsramme: 1 hour
Staff obtained responses from persons WITH diabetes (329) using short questionnaires to provide feedback on instructions for use and the basic operation of the BGMS. Subjects could respond 'Strongly Agree' or 'Agree' or 'Neutral' or 'Disagree' or 'Strongly Disagree.'
1 hour
Number of Self-Test Fingerstick Blood Glucose (BG) Results Within +/- 15% of Laboratory Glucose Method Across the Tested Glucose Range
Tidsramme: 1 hour

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% of the laboratory method across the entire tested YSI glucose range.
1 hour
Number of Self-Test Fingerstick Blood Glucose (BG) Results Within +/- 20% of Laboratory Glucose Method Across the Tested Glucose Range
Tidsramme: 1 hour
