No need for aminocentisis at this point.
If AFP result is positive, then you need to worry about it a little bit. Please read this link:

Alpha-fetoprotein normal range in blood of Women 15–22 weeks pregnant(Normal AFP values may vary from lab to lab. Values are generally slightly higher for black women than they are for white women. Values are slightly lower for Asian women than they are for white women):
19–75 IU/mL(international units per milliliter)
7–124 ng/mL(nanograms per milliliter)
7–124 mcg/L(micrograms per liter)
High alpha-fetoprotein values in a pregnant woman can mean:
1.The age (gestational age) of the baby is wrong.
2.The woman is pregnant with more than one baby, such as twins or triplets.
3.The baby has a neural tube defect.
4.The baby's intestines or other abdominal organs are outside the body (called an abdominal wall defect or omphalocele). Surgery after birth will be needed to correct the problem.
5.The baby is not alive.
In a pregnant woman, a low level of alpha-fetoprotein can mean:
1.The age (gestational age) of the baby is wrong.
2.The baby has Down syndrome.
If the AFP results are abnormal. An ultrasound will likely be done. If an ultrasound cannot find the cause of the abnormal AFP, an amniocentesis may be recommended.
