    Area of Science:

    • Biomedical Engineering
    • Analytical Chemistry
    • Hematology

    Background:

    • Erythrocyte zinc protoporphyrin (ZPP) is a biomarker for iron deficiency and lead poisoning.
    • Accurate and rapid ZPP measurement is crucial for timely diagnosis and treatment.
    • Existing methods may require complex sample preparation or specialized laboratory equipment.

    Purpose of the Study:

    • To introduce a novel portable filter fluorometer, the hematofluorometer.
    • To enable rapid, on-site assay of erythrocyte zinc protoporphyrin in unprocessed blood.
    • To provide a user-friendly instrument for both field and laboratory applications.

    Main Methods:

    • The hematofluorometer employs "front face" optics, internal standards, and digital computation.
    • A small finger-prick blood sample is applied to a disposable cover slip.

    Related Experiment Videos

  • The sample is inserted into the instrument for automated analysis.

    • Main Results:

    • The instrument provides rapid (approximately 5 seconds) assay of erythrocyte zinc protoporphyrin.
    • Results are automatically computed and displayed digitally in micrograms per deciliter.
    • No calibration adjustments are required by the operator.

    Conclusions:

    • The hematofluorometer offers a fast and convenient method for ZPP determination.
    • Its portable design makes it suitable for point-of-care testing and field studies.
    • The instrument simplifies ZPP analysis, enhancing accessibility for clinical and research settings.
