Blood Test to determine sex of baby?
Answer:
Usually you may have it checked by ultrasound at the about 20th weeks of pregnancy though determination may sometimes not be certain when done earlier.
I am not so certain about such blood test for fetal sex determination so I searched and quite surprised to see articles about such blood test. The controversial "Baby Gender Mentor" is something I haven't heard of. The test's reliability remain unknown however it remains on the market. Other companies also has similar product and recently the test called "Pink and Blue" became available through the internet.
Though there are issues and controversies on fetal sex determination with blood test it seems to be possibly true.
(Thanks for this question, I learned something and please note that I edited my answer.)
Probably, but you can find out through an ultrasound for sure at 20 weeks.
She could have an amniocentesis done, but that removes amniotic fluid from the amniotic sack, so that is not the same as a blood test. You can do this procedure sooner then when the ultra sound would be able to determine the sex and this procedure can also be used to screen for genetic disorders. It is a common procedure recommended for women over 35, but when a women is less then 35 the risk of a genetic disorder is so much less that the procedure is not typically performed because of the slight possibility of miscarriage. But, no, there is NOT a blood test that could reveal this information.
Why go for a blood test when ultrasound is noninvasive/nonpainful and probably even cheaper? You ca do chorioic villus sampling or amniocentesis to karyotype the baby--look into his chromosome, but in the preggy mom's blood...i dont think ive heard of any
The blood test for fetal cells in the maternal circulation is particularly difficult, slow and expensive but it could be used to determine gender. Ultrasound can be much more rapid.
I can usually see females at 14-15 weeks and males at 16 weeks.

not that i know of, a sonogram will tell you a educated guess of the doctor looking at it (but is not a definite). You can test amnio fluid (through an amniocentesis) and that is 100% accurate but drastic if the sex of the baby is only needed
