    Area of Science:

    • Forensic Science
    • Clinical Chemistry
    • Immunogenetics

    Background:

    • Accurate ABO blood group determination is crucial for transfusions and forensic investigations.
    • Current methods primarily rely on blood or saliva, which may not always be available.
    • Urine presents a potential alternative source for ABO typing.

    Purpose of the Study:

    • To evaluate the feasibility and reliability of ABO blood group typing directly from urine samples.
    • To assess the impact of sample collection, storage conditions, and physiological states on urine ABO typing accuracy.

    Main Methods:

    • ABO typing was performed on 46 urine samples with pre-determined ABO groups and secretor statuses from blood and saliva.
    • Blind, time, and storage studies were conducted on 24 urine samples.

  • Urine samples from multiple individuals, including pregnant and menstruating females, were analyzed.

    • Main Results:

    • Successful ABO typing was achieved for all 46 urine samples.
    • The test demonstrated reliability across blind, time, and storage studies.
    • ABO typing from urine was not significantly affected by physiological conditions such as pregnancy or menstruation.

    Conclusions:

    • Urine is a viable and reliable source for ABO blood group typing.
    • The developed method offers a non-invasive alternative for ABO determination in various clinical and forensic settings.
