A kit to tell whether your foetus is boy or girl?

Actually I was looking for info to find out how a pregnancy kit works but then saw this website about this kit that can help to detect whether your foetus is boy or girl really amaze me. A pregnancy kit works by detecting the presence of hCG (Human Chorionic Gonadotrophin) that is produced from a growing embryo. Normally it can only be detected a week after conception.

It works by mixing your urine with a conjugated antibody (or we can say an antibody that gives a signal). If your urine contain hCG, it will bind to the antibody and then attached itself on the immobilised antibody that is embedded on the front of the kit and this conjugated antibody will show a band at the area.If there is no hCG, these conjugated antibody will continue to flow toward the end of the pregnancy kit and bind on the antigen (can be human Chrionic Gonadotrophin) that is embedded on the kit. This will shows a band at the end of the kit which is the negative control. In conclusion, it tells us that if 2 bands are shown, congratuation! You are pregnant. But if only one negative band is shown mean you are not pregnant. If no band is shown mean that this kit is not working as it may not have enough conjugated antibody to show the signal.

So after pregnant, sure anxious about it sex right. Forget about those ultrasound scan which is so difficult to see and not specific. Now there is a kit where you can know the sex of your baby when you are just 10 week pregnant. I am not sure whether this kit is sold in Singapore or not as I just happen to see it in the net. It determine the sex of the foetus by looking for the Y chromosomal DNA in the mother blood using real time PCR. For your information, a male foetus have XY chromosome and female foetus have XX chromosome. So aren't we detecting mother cell instead of baby cells? No. It is because fetal cell will die and pass into the bloodstream of the mother. Furthermore mother do not have Y chromosome, so once Y chromosome is detected, it can be sure that it is from your fetus. For those who are interested to buy you can visit this website: http://www.tellmepinkorblue.com/. I am not sure whether they import to Singapore or not but is really not cheap (cost USD244). If really too much trouble then just wait patiently and let your doctor detect for you bah:)
