What does a low alpha fetoprotein level mean?

What does a low alpha fetoprotein level mean?

Further testing by amniocentesis will rule this out. It may also b a red flag for intrauterine growth restriction and preterm birth. Will need closer observation and testing. ...Read more

What can cause an elevated alpha fetoprotein level?

Different diseases: In pregnancy, elevated alpha fetoprotein levels in a woman's serum can indicate fetal abnormalities, like neural tube defects (spina bifida) or ventral wall defects like omphalocele.

My blood level of alpha fetoprotein is 29. What does this mean?

AFP=29: Normal range for AFP in 15-18-week-pregnant female is 10-150 ng/ml or mcg/l; normal range in non-pregnant female is 0-40 ng/ml or mcg/l. See chart for interpretation of high or low values (yours is in normal range). ...Read more

1980's: The Alpha fetoprotein test was around when i was a resident physician. The test has progressed through the y ears such that there are four levels measured in the pregnant woman's blood looking for the risk of down's syndrome (trisomy 21), trisomy 18 & neural tube defects like spina bifida. This is called the quadruple screen best measured between 16 & weeks of pregnancy. ...Read more

Can dehydration cause slightly elevated alpha fetoprotein?

Can dehydration cause slightly elevated alpha fetoprotein?

Dehydration and labs: Dehydration can raise some blood values. Most notably, sodium, chloride, BUN and creatinine are elevated due to less water in the blood.

This is a test that includes AFP and three other blood chemicals to screen for Trisomy 18, Trisomy 21 and Neural Tube defects. If the quad screen is abnormal, a referral to see a perinatologist for a detailed ultrasound and additional testing is in order. AFP can also be tested as part of a cancer work-up. ...Read more
