    Summary
    This summary is machine-generated.

    The sucrose test can detect a plasma haemolytic factor in patients with blood diseases. This test was positive in 17% of leukemia patients, but typically negative in healthy individuals and those with other diseases.

    Area of Science:

    • Hematology
    • Clinical Chemistry

    Context:

    • The sucrose test is a diagnostic tool used to assess the presence of specific factors in blood.
    • Erythrocyte hemolysis in sucrose solutions can indicate underlying pathological conditions.

    Purpose:

    • To evaluate the utility of the sucrose test in identifying plasma haemolytic factors.
    • To determine the prevalence of a positive sucrose test in patients with blood diseases, other diseases, and healthy controls.

    Summary:

    • The sucrose test was performed on 29 patients with blood diseases, 40 with other diseases, and 22 healthy blood donors.
    • The percentage index of erythrocyte hemolysis was calculated after incubation with serum in a 10% sucrose solution.
    • The test results were evaluated across four variants, including tests against own and foreign erythrocytes, and autohemolysis.

    Related Experiment Videos

  • The sucrose test was predominantly negative in healthy controls and patients with non-hematological diseases.
  • A positive sucrose test was observed in 17% of leukemia patients, suggesting its potential role in diagnosing hematological malignancies.

    • Impact:

    • This study highlights the sucrose test's potential as a diagnostic marker for certain blood disorders, particularly leukemia.
    • The findings contribute to understanding the role of plasma haemolytic factors in disease pathogenesis.
    • Further research may validate the sucrose test for broader clinical application in hematology.
