Positive alpha-fetoprotein:
2. Positive AFP in hepatocellular carcinoma examination. In this case, AFP will not decline naturally, instead, it manifests as persistent presence or persistent AFP positivity.
3, AFP positive after acute hepatitis or after active chronic hepatitis, due to hepatitis caused by a large number of liver cell necrosis, liver cell regeneration during the recovery period, thus causing AFP positive. At this time, the level of AFP should be observed dynamically. Generally speaking, after the regeneration of liver cells, AFP will gradually decrease to the normal level.
Alpha-fetoprotein negative:
Alpha-fetoprotein negative, that is to say, in the serum can not be detected in the alpha-fetoprotein or alpha-fetoprotein content is very low, almost negligible. In the quantitative examination of alpha-fetoprotein, if the radioimmunoassay alpha-fetoprotein test value Question 2: What is the normal value of alpha-fetoprotein alpha-fetoprotein measurement methods are different, the normal value of the level is also different, the measurement method is mainly enzyme labeling, enzyme labeling electrophoresis, radioimmunoassay detection of the three methods of measurement, the normal value of the range is as follows:
1. alpha-fetoprotein (AFP) measured by enzyme-linked immunoassay The normal value when AFP is measured by enzyme immunoassay is: ≤25 μg/L.
2. The normal value when AFP is analyzed by radioimmunoassay is: ≤20 μg/L.
3. The normal value when AFP is measured by radioimmuno-electrophoresis is: ≤25 μg/L. (Key note: If it is between 25 and 400 ug/L, it is a positive low concentration, and if it exceeds 400 ug/L, it is a positive high concentration, and it is a positive high concentration. /L is a high-concentration positive, and if the elevation of alpha-fetoprotein is modest, at 50 ug-300 ug/L, it may be viral hepatitis).
Question 3: What is the high quantitative alpha-fetoprotein test value ? In adults, elevated alpha-fetoprotein is present in the serum of approximately 80% of patients with hepatocellular carcinoma. AFP was initially used for the early diagnosis of liver cancer, and normal human serum levels of AFP are typically less than 20 micrograms per liter. However, when liver cells become cancerous, alpha-fetoprotein is elevated. Therefore, we tend to be very nervous when high alpha-fetoprotein is detected. In order to make everyone understand this problem better, here we will look at what high alpha-fetoprotein quantitative test value means in detail. First of all, we have to consider the viral hepatitis, chronic hepatitis active alpha-fetoprotein has a mild, moderate elevation, generally in the 50-300ug / L, and hepatocellular carcinoma is different for the low amplitude of the elevation, generally do not continue to increase, after treatment to reduce or even restore. Neonatal hepatitis, alpha-fetoprotein can be measured in 30% of neonatal hepatitis, the incidence of which increases with the severity of the disease, and is mostly markedly elevated. This can be differentiated from congenital biliary atresia, in which alpha-fetoprotein is mostly normal. Secondly, alpha-fetoprotein is a specific tumor marker for the diagnosis of primary liver cancer. The quantitative test of alpha-fetoprotein is to detect the size of its value, while the qualitative test is positive and negative, and it is positive if it is greater than the normal value, and the amount of alpha-fetoprotein in the serum of a normal human being is less than 20 micrograms/liter. High quantitative alpha-fetoprotein values can be seen in cancerous liver cells, pregnant women and newborns, non-malignant diseases (acute and chronic hepatitis, cirrhosis, etc.), germ cell tumors, and so on. In addition, the high value of alpha-fetoprotein quantitative test must attract our attention, usually the newborn will appear in the body of alpha-fetoprotein is high, which is a normal hematopoietic function. It is recommended that patients should check the value of alpha-fetoprotein regularly, if it is only mildly or moderately elevated, generally less than 400 μg/L, and the time of continuous elevation is short, two to three weeks will start to decline, sometimes not decline but not continuously rise, this situation belongs to the hepatitis; if alpha-fetoprotein continues to rise more than 400 μg/L, even up to 1,000 μg/L, or rise and fall irregularly and capriciously, it may be malignant tumor, or a precursor of liver cancer. In short, hepatitis B patients with high alpha-fetoprotein must be actively treated to prevent further deterioration of the patient's condition. Shijiazhuang *** 256 Liver Disease Hospital is equipped with the most sophisticated international liver disease medical equipment, for liver disease diagnosis and treatment to provide a scientific basis, so that it is in the treatment of hepatitis B major and minor triple, liver fibrosis, cirrhosis, fatty liver, alcoholic liver and other liver diseases such as tiger wings, in the domestic leading level.
Question 4: What is the meaning of AFP quantification of 5.23? AFP is closely related to liver cancer, but generally higher than 400 to consider the possibility of tumor. mildly elevated AFP is a manifestation of liver inflammation. Your data is only 5.23, which is lower than the upper limit of normal, there is no problem, don't worry. Suggestion: Your AFP belongs to the normal range, there is no problem, if there is no problem in other aspects of the examination, there is no need to do a comprehensive examination. It is recommended that regular physical examination can be.
Question 5: What is the role of qualitative testing of alpha-fetoprotein After acute hepatitis or chronic hepatitis activity, liver cell repair and regeneration during the recovery period, the newborn hepatocytes will produce alpha-fetoprotein, which causes alpha-fetoprotein elevation, at this time, we need to carry out quantitative testing of alpha-fetoprotein, and dynamically observe the level of alpha-fetoprotein, in general, after regeneration of hepatocytes with the recovery of liver function, alpha-fetoprotein will gradually decline to the normal level. Generally speaking, with the recovery of liver function after regeneration of liver cells, alpha-fetoprotein will gradually decrease to normal level. However, when hepatocellular carcinoma occurs, the level of alpha-fetoprotein in the serum will increase sharply as the condition deteriorates. Alpha-fetoprotein is a specific clinical indicator for the diagnosis of primary hepatocellular carcinoma, which has the function of establishing diagnosis, early diagnosis and differential diagnosis.
Positive alpha-fetoprotein:
2. Positive AFP in hepatocellular carcinoma examination. In this case, AFP will not decline naturally, instead, it manifests as persistent presence or persistent AFP positivity.
3, AFP positive after acute hepatitis or after active chronic hepatitis, due to hepatitis caused by a large number of liver cell necrosis, liver cell regeneration during the recovery period, thus causing AFP positive. At this time, the level of AFP should be observed dynamically. Generally speaking, after the regeneration of liver cells, AFP will gradually decrease to the normal level.
Alpha-fetoprotein negative:
Alpha-fetoprotein negative, that is to say, in the serum can not be detected in the alpha-fetoprotein or alpha-fetoprotein content is very low, almost negligible. In the quantitative examination of alpha-fetoprotein, if the radioimmunoassay alpha-fetoprotein test value Question 6: What is the normal value of alpha-fetoprotein The measurement of alpha-fetoprotein is different, the normal value of the level is also different, the measurement method is mainly enzyme labeling, enzyme labeling electrophoresis, radioimmunoassay detection of the three methods of measurement, the normal value of the range is as follows:
1. alpha-fetoprotein (AFP) measured by enzyme-linked immunoassay The normal value when AFP is measured by enzyme immunoassay is: ≤25 μg/L.
2. The normal value when AFP is analyzed by radioimmunoassay is: ≤20 μg/L.
3. The normal value when AFP is measured by radioimmuno-electrophoresis is: ≤25 μg/L. (Key note: If it is between 25 and 400 ug/L, it is a positive low concentration, and if it exceeds 400 ug/L, it is a positive high concentration, and it is a positive high concentration. /L is a high-concentration positive, and if the elevation of alpha-fetoprotein is modest, at 50 ug-300 ug/L, it may be viral hepatitis).

Question 8: What is quantitative alpha-fetoprotein. It is generally used as an indicator to assist in the diagnosis of liver cancer.
Question 9: The quantitative alpha-fetoprotein (AFP) is high There is no problem, because you are a hepatitis B triple, that is, hepatitis B virus carriers, especially if there is no antiviral treatment, then the hepatitis B virus will keep destroying the liver cells, and after that the liver cells will regenerate on their own, and this process in itself will lead to the elevation of the alpha-fetoprotein, but your alpha-fetoprotein elevation is too little, not However, the elevation of your alpha-fetoprotein is too small, not higher than 200, not to mention more than 500, and the ultrasound of the liver did not see obvious abnormalities, so do not consider liver cancer.
