LISS--an effective way to increase blood utilization.

G Rock, A Baxter, M Charron

    Transfusion
    |March 1, 1978
    PubMed
    Summary

    The low ionic strength solution (LISS) method enhances antibody detection sensitivity for blood transfusions. This technique improves blood utilization and reduces unnecessary crossmatches, especially for elective surgery standby procedures.

    Area of Science:

    • Transfusion Medicine
    • Immunoserology

    Background:

    • Blood crossmatching is crucial for safe transfusions.
    • Existing methods for antibody detection have limitations in sensitivity and efficiency.

    Purpose of the Study:

    • To compare the efficacy of the low ionic strength solution (LISS) method with automated and manual techniques for antibody detection.
    • To evaluate the impact of LISS on blood utilization and crossmatching practices in elective surgery.

    Main Methods:

    • Comparison of Low and Messeter's low ionic strength solution (LISS) with automated low ionic strength Polybrene and manual IDAT techniques.
    • Optimization of incubation times (5 and 15 minutes) for LISS to assess antibody detection sensitivity and titer.

    Main Results:

    • A 5-minute incubation with LISS detected all significant antibodies.
    • Extending incubation to 15 minutes increased reaction sensitivity (titer) beyond other methods.
    • Implementation in elective surgery standby procedures reduced unnecessary crossmatches by 1,600 units and increased blood utilization by 10% over nine months.

    Conclusions:

    • The LISS method offers superior sensitivity for antibody detection compared to existing techniques.
    • LISS enhances the efficiency and effectiveness of blood management strategies, particularly for standby procedures in elective surgery.
