Trial Outcomes & Findings for Biolinq External Interferent Protocol (NCT NCT06560177)

NCT ID: NCT06560177

Last Updated: 2026-02-13

Results Overview

This measures how often (percentage), within the first hour after taking APAP, the Biolinq sensor's color matches the YSI blood sugar readings. BLUE on the sensor means a glucose level between 70 and 180 mg/dL, which matches YSI values from 55 to 207 mg/dL. YELLOW means a sensor reading between 181 and 400 mg/dL, matching YSI values from 154 to 460 mg/dL.

Participant Flow

Randomization allocation was 1:1 between left and right volar forearm in order to negate possible performance bias between locations. It was pre-specified in the study protocol to report the baseline and outcome measure data for participants irrespective of placement of sensors.

PRIMARY outcome

Timeframe: First hour post Acetaminophen (APAP) intake

Population: Performance analysis was limited to 28 sensors with matching YSI values. It was pre-specified in the study protocol to report the outcome measures for participants irrespective of arm randomized for placement of sensor.

This measures how often (percentage), within the first hour after taking APAP, the Biolinq sensor's color matches the YSI blood sugar readings. BLUE on the sensor means a glucose level between 70 and 180 mg/dL, which matches YSI values from 55 to 207 mg/dL. YELLOW means a sensor reading between 181 and 400 mg/dL, matching YSI values from 154 to 460 mg/dL.
