PIVKA II (Protein Induced by Vitamin K Absence or Antagonist-II) is a specialized tumor marker used in the diagnosis and monitoring of liver diseases, particularly hepatocellular carcinoma (HCC). This protein is produced abnormally in the liver when vitamin K-dependent carboxylation is impaired, often associated with malignant transformations.

PIVKA II testing involves analyzing blood samples to measure the levels of this abnormal protein. Elevated levels may indicate liver cell dysfunction or the presence of HCC, although other liver disorders can also influence readings. It is commonly used in conjunction with other biomarkers, imaging studies, and clinical assessments for more accurate diagnosis.

Clinical applications include monitoring disease progression, evaluating treatment efficacy, and detecting recurrence after surgery or therapy. Because PIVKA II levels correlate with tumor size and aggressiveness, it provides valuable prognostic information. Regular testing is essential in high-risk patients, including those with chronic hepatitis, cirrhosis, or a history of liver cancer.

PIVKA II assays are designed to be highly sensitive and specific, minimizing false positives and improving diagnostic reliability. Pre-analytical factors, such as vitamin K intake, anticoagulant use, or liver function, may influence results and should be considered when interpreting the test.

Overall, the PIVKA II tumor marker is an important tool in hepatology, enhancing early detection, guiding treatment decisions, and supporting comprehensive patient management.
