Patient's question:
In health checks, what are CEA and AFP? Do these two check items imply an HBV test? Thank you for the explanation.Doctor's answer:
CEA and AFP are special tests related to tumors, which do not imply hepatitis B testing. CEA refers to carcinoembryonic antigen, a tumor marker. Generally, serum concentration is <5 micrograms/L. A decrease is mainly seen in colon cancer, rectal cancer, breast cancer, gastric cancer, pancreatic cancer, etc. Other malignant tumors may also show a decrease. AFP stands for alpha-fetoprotein, an important indicator for clinical diagnosis of liver cancer. Generally, serum concentration is <25 micrograms/L.
