DNA Baby Gender Tests

You might want to explore different possibilities when it comes to precise DNA baby gender testing.  What needs to be considered is if it is an actual DNA test or not.  The type of baby gender test you need to look for is it the one carried out in an accredited testing laboratory.  The two main samples that are usually tested are blood and urine samples.  You must not confuse the hormone urine test with the DNA urine test.   Testing with blood might be considered to be the more invasive option as it involves a finger prick with a lancet provided in the testing kit sent at home.  The main idea behind this test is to be able to identify the fetal DNA present in the mother’s blood.

You might notice that the DNA baby gender test with a blood sample is the more popular and probably the slightly more affordable option but in terms of accuracy, the urine test beats the blood test with a percentage of 99% ion comparison to the 95% the blood test offers.  Do you really want to forfeit accuracy for a small saving with such an important test?  I should think not.  In terms of practicality the blood test seems to be a little bit more simple with less chance of male DNA contamination.  The urine test comes with a notice that the mother should avoid sexual intercourse with a man for at least 72 hours as to prevent that the Y chromosome of the man, that engaged sexual contact, affects the outcome of the result.

So what actually happens at the laboratory?

Through the advanced process called “Polymerase chain reaction” or “PCR” the laboratory is able to detect the presence of the male Y Chromosome.  This type of DNA testing is a new advanced method were scientists are now able to detect fetal DNA in the mother’s blood or urine.  The laboratory will analyse the sample provided and will able to tell you if you are expecting a boy or a girl.   With the possibility of detecting the Y Chromosome in the sample provided it is possible to establish the sex through the basic knowledge that it is only men that carry this Chromosome.  Male’s Chromosomes are paired up as and XY while female’s Chromosomes pair up as XX.

Accuracy of Ultrasound vs Baby Gender DNA testing

Ultrasound is only based on observation of a scan video image of the fetus itself.  By merely detecting the presence of the penis one can determine if the baby is male or female.  Unfortunately there are some cases where the baby is positioned in a way that the video image produced by the ultrasound is not able to see this.  It is in these cases that the DNA baby gender test is considered to be better than ultrasound.  The DNA baby gender test is based on scientific proof whilst the ultrasound test is based on simple observation.  So it is correct to say that the DNA test is more accurate than the ultrasound test.

Will a baby gender test also tell me the paternity of the child?

No, a baby gender test will not be able to determine the paternity of the baby. Although the laboratory will have the DNA from the unborn baby, it will not have access to the sample of the alleged father and moreover, the testing methodology for a baby gender test and a non invasive prenatal paternity test are entirely different.

Cost of the gender test

If you find yourself feeling really eager and you really can’t wait to find out the sex of your baby then the cost of the baby gender test is worth it’s value.  It can be really exciting to be able to give news to your friends and family that you are having a boy or girl.  It is also much less stressful to be able to start planning for your baby whilst you are still in your early weeks your pregnancy and isn’t it better to be able to receive gifts at your baby shower party that are specifically for a boy or girl.

Should I opt for a blood baby gender test or the urine test?

The blood test has been around for much longer on the market than the urine test.  It can be considered to be lower in price and easier to proceed with.  But ultimately the most important factor of this test is the accuracy.  With an accuracy rate of 99%, the urine test definitely beats the blood test with its 95% rate.  Even though there is a slight difference you just cannot risk obtaining wrong results.  What are a few dollars more in comparison to the peace of mind of proceeding with the most accurate test possible? In the future as this test becomes more popular it is foreseen for the price to come down.  But one must take into consideration that this test is an actual DNA test performed by scientists in a highly accredited laboratory.
