Final answer:
The alpha-fetoprotein (AFP) test is a blood test that measures the level of AFP in the blood. It is used to detect, diagnose, and monitor diseases, particularly liver cancer and other conditions related to the liver.
Step-by-step explanation:
The alpha-fetoprotein (AFP) test is a blood test that measures the level of AFP in the blood. AFP is a protein produced by the liver and yolk sac during fetal development. In adults, elevated AFP levels may be a sign of liver disease or certain types of cancer, including liver cancer and testicular cancer.
AFP testing is commonly used as a screening tool for liver cancer in individuals at high risk, such as those with chronic hepatitis B or C infection or a history of liver disease. It can also be used to monitor cancer survivors for recurrence or to assess the effectiveness of treatment.
Overall, the AFP test helps in the detection, diagnosis, and monitoring of certain diseases, particularly liver cancer and other conditions related to the liver.
