Introduction
If the elevation is caused by physiological factors—such as in pregnant women (fetal hepatocytes secrete alpha-fetoprotein into the maternal circulation), recent intense exercise, or sleep deprivation—and the individual has no symptoms such as abdominal pain or jaundice, the levels usually return to normal gradually after removing these factors. In such cases, there is no need for excessive concern; regular follow-up testing is sufficient, and no special treatment is required.
In general, an alpha-fetoprotein (AFP) level of 11.3 ng/mL is slightly above the normal reference upper limit (typically 0–7 ng/mL). If the elevation is due to physiological factors, it usually poses no risk; however, if caused by underlying diseases, it warrants attention. If concerned, it is advisable to seek medical consultation promptly. Detailed analysis is as follows:
If the elevated AFP is caused by physiological factors—such as pregnancy (fetal hepatocytes secrete AFP into the maternal circulation), recent intense physical activity, or sleep deprivation—and there are no symptoms such as abdominal pain or jaundice, the value typically returns to normal gradually after eliminating these influencing factors. In such cases, there is generally no need for excessive concern; regular follow-up testing is sufficient, and no specific treatment is required.
If the elevation is associated with pathological conditions—such as primary liver cancer, active hepatitis, or liver cirrhosis—it may be accompanied by symptoms including dull pain in the liver area, decreased appetite, and weight loss. Failure to promptly investigate these causes may lead to delayed diagnosis and treatment. In such cases, further examinations—such as liver ultrasound and liver function tests—are necessary to determine the underlying cause. Dynamic monitoring of AFP levels may also be needed when appropriate, to observe whether the values continue to rise.
After detecting an AFP level of 11.3 ng/mL, first confirm whether you are in a special physiological state. For individuals without special circumstances, repeat testing after 1–2 months is recommended to monitor changes in AFP levels. If symptoms develop or the AFP level continues to increase, prompt medical evaluation and further testing are advised.
