What is the normal range for an AFP tumor marker?
An AFP level between 10 ng/mL to 20 ng/mL is normal for adults. An extremely high level of AFP in your blood—greater than 400 ng/mL—could be a sign of liver tumors. High levels of AFP may mean other cancers, including Hodgkin disease, lymphoma, and renal cell carcinoma (kidney cancer).
Does high afp always mean cancer?
Increased AFP levels may indicate the presence of cancer, most commonly liver cancer, cancer of the ovary, or germ cell tumor of the testicles. However, not every liver, ovarian, or testicular cancer will produce significant quantities of AFP.
What does AFP positive mean?
A positive AFP PLUS test means that you are in a higher likelihood group for having a baby with a neural tube defect or a chromosome abnormality. However, it does not prove by itself that there is anything wrong with the pregnancy.
Do tumor markers mean cancer?
Although an elevated level of a circulating tumor marker may suggest the presence of cancer and can sometimes help to diagnose cancer, this alone is not enough to diagnose cancer. For example, noncancerous conditions can sometimes cause the levels of certain tumor markers to increase.
What is considered a high tumor marker?
Normal range may vary somewhat depending on the brand of assay used. Levels > 10 ng/ml suggest extensive disease and levels > 20 ng/ml suggest metastatic disease.
How accurate are AFP results?
AFP had high overall accuracy, with a c-statistic of 0.87 (95%CI 0.85 – 0.89). Most importantly, we found that patient characteristics influenced the performance of AFP and could be used to define subgroups in whom it performed particularly well.
Can tumor markers be high without cancer?
A condition or disease that is not cancer can raise tumor marker levels. People without cancer can have high tumor marker levels. Tumor marker levels can change over time. The tests may not get the same result every time.
What cancers can AFP detect?
High levels of AFP can be a sign of liver cancer or cancer of the ovaries or testicles, as well as noncancerous liver diseases such as cirrhosis and hepatitis. High AFP levels don’t always mean cancer, and normal levels don’t always rule out cancer.
What non cancerous conditions can cause tumor markers?
Guide to Tumor Markers Used in Cancer
| Tumor Marker | |
|---|---|
| Blood test (blood serum marker), except where noted. | |
| Non-Cancerous Reasons for Elevated Levels | Cigarette smoking, pancreatitis, hepatitis, inflammatory bowel disease, peptic ulcer disease, hypothyroidism, cirrhosis, COPD, biliary obstruction |
What does high alpha fetoprotein tumor marker mean?
What do the results mean? If your results show high levels of AFP, it may confirm a diagnosis of liver cancer, or cancer of the ovaries or testicles. Sometimes, high levels of AFP can be a sign of other cancers, including Hodgkin disease and lymphoma, or noncancerous liver disorders.
What causes tumor markers to go up?
Tumor marker levels may be higher when there is cancer in the body. They are not very “specific,” meaning non-cancer health issues can also cause these levels to be higher. They must be used along with radiology tests and exams by your healthcare provider.
What can raise AFP levels?
Alpha-fetoprotein (AFP) is a protein produced primarily by the liver in a developing baby (fetus). AFP levels are normally elevated when a baby is born and then decline rapidly. Outside of pregnancy and birth, liver damage and certain cancers can increase AFP levels significantly.
How to interpret AFP results?
– There is no risk for you and the fetus. – Only points out the chances of defects of the unborn baby. – Other tests should be done if the results indicate any abnormality.
What is the normal range for AFP?
What is the normal range for an AFP tumor marker? An AFP level between 10 ng/mL to 20 ng/mL is normal for adults. An extremely high level of AFP in your blood—greater than 400 ng/mL—could be a sign of liver tumors. High levels of AFP may mean other cancers, including Hodgkin disease, lymphoma, and renal cell carcinoma (kidney cancer).
How to detect cancer with a blood test?
Tumor marker tests. Tumor markers are chemicals produced by cancer cells and found in the blood.
What causes elevated tumor markers?
Tumor marker levels can be elevated in people with benign conditions.
