    Area of Science:

    • Clinical Chemistry
    • Laboratory Medicine
    • Point-of-Care Testing

    Background:

    • Accurate blood glucose monitoring is vital for diabetes management.
    • Home-based blood collection introduces variables affecting sample integrity.
    • Standardized pre-analytical conditions are essential for reliable diagnostic testing.

    Purpose of the Study:

    • To investigate the influence of pre-analytical variables (time, temperature) on blood glucose measurements from home-collected samples.
    • To establish optimal handling and transport protocols for home-drawn blood specimens.

    Main Methods:

    • Blood samples were collected via venipuncture in a home setting.
    • Samples were subjected to varying time delays and storage temperatures before laboratory analysis.

  • Glucose levels were measured using standard laboratory assays.

    • Main Results:

    • Significant degradation of glucose levels was observed with increased time and elevated temperatures.
    • Specific time-temperature thresholds were identified that compromise sample accuracy.
    • Variability in glucose results increased under suboptimal transport conditions.

    Conclusions:

    • Home healthcare nurses must prioritize rapid, temperature-controlled transport of blood samples to the laboratory.
    • Adherence to strict pre-analytical procedures is critical for maintaining the integrity of glucose measurements from home-drawn samples.
    • Timeliness and appropriate temperature management are key factors for reliable point-of-care glucose testing in home settings.
