Follow a glucose repeatability study from setup to report.

Follow a single-run repeatability study of one glucose control. Set the CV limit, import the readings, exclude a transcription error and review the calculated results and report.

  1. Set up

    Name the analyte and set the CV limit.

    Choose New study, select Repeatability and enter the analyte, Glucose, and the unit, mg/dL. Under Acceptance limits, add the laboratory's limit for the repeatability CV, ≤ 1%.

    Set up for Glucose · repeatability: the study details and the acceptance limit, repeatability CV ≤ 1%.

  2. Data

    Import the run and exclude the transcription error.

    Import repeatability.csv, which holds 21 readings of control QC-001 from one run.

    On Data, row 9 reads 1004, a transcription error. The row is excluded with that reason, so it stays in the study and is left out of the calculation.

    Data for Glucose · repeatability: 21 readings of QC-001 in one run, with row 9, 1004, marked excluded and its reason.

  3. Results

    Calculate the CV against your limit.

    Choose Calculate results. The study reads Criteria met, with 20 analyzed and 1 excluded: CV 0.93% against the limit of ≤ 1%, Met.

    Key results give the mean, 100.17 mg/dL (95% CI 99.73–100.61), and the SD, 0.936 mg/dL. The run-order plot marks the excluded 1004 off scale.

    Results for Glucose · repeatability: Criteria met, 20 analyzed and 1 excluded, CV 0.93% against the limit of ≤ 1%, and the results in run order.

  4. Report

    Download, print or sign off the report.

    On Report you can Download PDF, Print or, if your procedure calls for it, Sign off.
