Fetoprotein is a commonly used tumor marker, and often greater than 100 ug/mL has more clinical significance, especially in relation to tumors. For alpha-fetoprotein less than 100 micrograms / ml, but also greater than the normal value range, the clinical significance is not exact, can lead to mild elevation of alpha-fetoprotein cause hepatitis, tumor, pregnancy, etc., due to a variety of causes, so we need to analyze the causes according to the patient’s specific situation. Can not specify the cause, should be checked once a month to observe the changes in this indicator, for stable or decline, do not worry, persistent elevation, should be improved in a timely manner other tests.
