Alpha-Fetoprotein (AFP) is a protein produced by the liver during fetal development. In adults, elevated AFP levels can indicate liver disease or certain types of cancer, particularly liver cancer and testicular cancer. This test is used to: 1. Screen for liver cancer in high-risk individuals 2. Monitor treatment effectiveness in patients with liver or testicular cancer 3. Assess the risk of certain birth defects during pregnancy AFP levels can also be elevated in non-cancerous liver conditions, such as cirrhosis or hepatitis. Regular monitoring of AFP levels, along with other diagnostic tests, helps in early detection and management of liver diseases and certain cancers.
A low AFP level (below 0 ng/mL) is generally not a cause for concern in adults. In fact, AFP levels are expected to be very low or undetectable in healthy adults. However, during pregnancy, abnormally low AFP levels might indicate:
It’s important to note that a single low AFP result should not be considered diagnostic. Further testing and consultation with a healthcare provider are necessary for proper interpretation.
Elevated AFP levels (above 10 ng/mL) can indicate several conditions:
However, elevated AFP alone is not diagnostic. False positives can occur, and other factors like pregnancy or benign liver conditions can cause elevated levels. Additional tests, such as imaging studies or biopsies, are often needed for a definitive diagnosis. Regular monitoring and consultation with a healthcare provider are crucial for proper interpretation and management.
