The cytocentrifuge NBT test.

P A Gordon, J Stuart, T R Lee

    Journal of Clinical Pathology
    |August 1, 1975
    PubMed
    Summary

    A new cytochemical test improves neutrophil function analysis, especially for septic patients. This enhanced NBT test is reliable for both venous and capillary blood, even in neutropenic cases.

    Area of Science:

    • Clinical chemistry
    • Hematology
    • Immunology

    Background:

    • The Nitroblue tetrazolium (NBT) test assesses neutrophil function.
    • Studying neutrophil function is crucial, particularly in septic patients.
    • Existing laboratory methods may have sources of error.

    Purpose of the Study:

    • To develop an improved cytochemical NBT test.
    • To minimize laboratory errors in neutrophil function testing.
    • To evaluate the clinical utility of the enhanced NBT test.

    Main Methods:

    • Development of an improved cytochemical NBT test.
    • Utilized venous or capillary blood samples.
    • Employed cytocentrifugation to concentrate neutrophils for neutropenic patients.

    Main Results:

    • The improved NBT test eliminates potential laboratory errors.
    • The technique is applicable to both venous and capillary blood.
    • The method is effective for neutropenic patients due to neutrophil concentration.

    Conclusions:

    • The enhanced NBT test is a reliable method for studying neutrophil function.
    • This improved test has significant applications in clinical settings, especially for septic and neutropenic patients.
