    A novel diagnostic test, SickleQuikTM, offers a rapid and accurate method for detecting sickle hemoglobin. This innovative approach surpasses existing turbidity tests, providing clear results in under eight minutes.

    Area of Science:

    • Hematology
    • Clinical Diagnostics
    • Biochemistry

    Background:

    • Sickle cell disease diagnosis relies on accurate hemoglobin S (HbS) detection.
    • Existing turbidity tests for HbS have limitations in speed and differentiation.

    Purpose of the Study:

    • To introduce SickleQuikTM, a new diagnostic test for sickling hemoglobin.
    • To evaluate the advantages of SickleQuikTM over current diagnostic methods.

    Main Methods:

    • Utilized a biphasic liquid reagent system in ready-to-use reaction tubes.
    • Analyzed results based on color changes at the organic-aqueous interface and in the aqueous phase.
    • Tested over 900 samples in independent laboratory settings.

    Main Results:

    Related Experiment Videos

    • SickleQuikTM differentiates homozygous (HbSS) from heterozygous (HbAS) samples.
    • The test provides definitive results in less than eight minutes.
    • Achieved 100% accuracy with no false positive or false negative results in over 900 samples.

    Conclusions:

    • SickleQuikTM is a rapid, accurate, and advantageous alternative to existing sickle hemoglobin tests.
    • The test's ready-to-use format and room temperature stability enhance its clinical utility.
    • High accuracy in differentiating HbSS and HbAS genotypes supports its use in clinical diagnostics.
