diagnostic workup
The series of examinations and tests performed to evaluate abnormal screening findings and establish a definitive diagnosis.
Full Definition
A systematic approach to investigating abnormal findings detected during cancer screening, involving additional imaging, tissue sampling, or other diagnostic procedures. The diagnostic workup begins when screening identifies suspicious abnormalities and continues until a definitive diagnosis is reached, whether benign or malignant. This process may include diagnostic mammography following screening mammography, image-guided biopsies, endoscopic procedures, or surgical consultations. The efficiency and completeness of diagnostic workup directly impacts patient outcomes and screening program effectiveness, making timely and appropriate follow-up essential.
Usage
Usage note: Hyphenate when used as a compound modifier; distinguish from initial screening procedures.
