    Area of Science:

    • Biochemistry
    • Hematology

    Background:

    • The deoxyuridine suppression (dU) test is a key diagnostic tool.
    • It is vital for studying vitamin B12 and folate interrelationships in megaloblastic anemia.
    • Megaloblastic anemia pathogenesis involves vitamin B12 and folate.

    Purpose of the Study:

    • To highlight the diagnostic significance of the dU test.
    • To emphasize its role in understanding vitamin B12 and folate metabolism.
    • To explore its application in DNA synthesis pathway studies.

    Main Methods:

    • The dU test assesses the integrity of the de novo DNA synthesis pathway.
    • This pathway is essential for cellular function and DNA replication.
    • Vitamin B12 and folate are critical cofactors in this process.
