Mass screening for sickle cell hemoglobin. Is there an optimal method?

R M Nalbandian, F R Camp, R L Henry

    JAMA
    |November 24, 1975
    PubMed
    Summary

    Screening for sickle cell hemoglobin can be done using three methods. A dual, automated screening approach is most cost-effective and provides comprehensive data for diagnosis and genetic counseling.

    Area of Science:

    • Hematology
    • Medical Diagnostics
    • Public Health Screening

    Background:

    • Sickle cell hemoglobin and related conditions necessitate effective screening in large populations.
    • Current screening methods vary in approach and efficiency.

    Purpose of the Study:

    • To evaluate and compare three distinct screening methods for sickle cell hemoglobin.
    • To identify the most cost-effective and diagnostically valuable screening strategy.

    Main Methods:

    • Method 1: Initial hemoglobin electrophoresis followed by solubility test.
    • Method 2: Initial automated solubility (dithionite) test followed by electrophoresis.
    • Method 3: Dual automated screening for anemia/hemoglobin S, with electrophoresis as indicated.

    Main Results:

    • All three methods yield data suitable for diagnosis and genetic counseling.
    • Substantial variations exist in costs and data redundancy among the methods.
    • The dual, automated screening method offers the greatest diagnostic value for its cost.

    Conclusions:

    • The dual, automated screening method is recommended for widespread adoption due to its efficiency and cost-effectiveness.
    • Optimized screening protocols are crucial for managing sickle cell hemoglobin in large populations.
