Evaluation of a new serum separator

D L Seckinger, D Antonio Vazquez, P K Rosenthal

    Clinical Chemistry
    |January 1, 1982
    PubMed
    Summary

    The Centri-Sep filter effectively separates serum for chemical analysis, yielding slightly more serum without compromising clinical results. It is not suitable for long-term serum storage on the clot.

    Area of Science:

    • Clinical Chemistry
    • Laboratory Medicine
    • Biomedical Engineering

    Background:

    • Accurate serum separation is crucial for reliable chemical analysis.
    • Existing serum separation methods may have limitations in efficiency and yield.
    • The Centri-Sep filter was developed to potentially improve serum separation processes.

    Purpose of the Study:

    • To evaluate the effectiveness of the Centri-Sep filter for serum separation from clotted blood samples.
    • To assess the impact of the Centri-Sep filter on the accuracy and clinical utility of serum analytes.
    • To compare the serum yield of the Centri-Sep filter with conventional decanting devices.

    Main Methods:

    • Paired t-test statistical analysis was employed.
    • Serum samples were processed using the Centri-Sep filter.
    • Results were compared to samples processed without a separator and with a serum-decanting device.
    • Analyte values were assessed for clinical usefulness.

    Main Results:

    • The Centri-Sep filter demonstrated effectiveness in separating serum.
    • Minor statistical differences were observed for some analytes compared to other methods.
    • The bias in paired means was minimal, indicating preserved clinical usefulness.
    • Approximately 10% more serum was obtained using the Centri-Sep filter compared to decanting devices.
    • The filter was found unsuitable for long-term serum storage on the clot.

    Conclusions:

    • The Centri-Sep filter is a viable option for serum separation in chemical analysis.
    • The device provides a slight increase in serum yield without compromising diagnostic accuracy.
    • Clinical laboratory professionals should consider the limitations regarding long-term serum storage.
