    Biochemical screening in general practice identified unsuspected diseases in 5.5% of patients. This diagnostic approach significantly improved patient outcomes compared to clinical feature-based testing.

    Area of Science:

    • General Practice
    • Biochemistry
    • Diagnostic Medicine

    Background:

    • Routine biochemical screening in primary care settings can reveal health issues.
    • Clinical features alone may not always indicate the need for specific diagnostic tests.

    Purpose of the Study:

    • To evaluate the effectiveness of a short biochemical screening program in identifying previously undiagnosed conditions.
    • To compare the diagnostic yield of comprehensive screening versus clinically indicated testing.

    Main Methods:

    • A cohort of 1,041 patients attending general practitioners underwent biochemical screening.
    • Results were compared to a hypothetical scenario where testing was based solely on clinical presentation.

    Main Results:

    • The screening program identified 64 results leading to changes in diagnosis or treatment in 57 patients (5.5% of those screened).
    • Clinically indicated testing would have identified only 15 abnormal results in 14 patients.

    Conclusions:

    • Biochemical screening programs are valuable for detecting unsuspected diseases in primary care.
    • Screening offers a higher diagnostic yield than relying exclusively on clinical features.
