Alpha-1-Fetoprotein.L3/Alpha-1-Fetoprotein.total
Measures the proportion of a specific type of AFP protein relative to total AFP in your blood.
Why This Biomarker Matters
This ratio is a sensitive marker for liver cancer risk. In patients with liver disease, an elevated ratio can indicate early-stage cancer, enabling prompt treatment before advanced progression.
Overview
Alpha-fetoprotein (AFP) is a protein produced during fetal development and in certain liver conditions. This test measures the ratio of AFP-L3 (a specific form) to total AFP, which is particularly useful for detecting hepatocellular carcinoma (liver cancer) and monitoring liver disease. Elevated AFP-L3 ratios are more specific for liver cancer than total AFP alone, making this test valuable for early cancer detection in patients with cirrhosis or chronic liver disease.
