Can I do a paternity test when I'm just pregnant?

You can do a paternity test when you are just pregnant, and it will not have any impact at all. However, many people think that paternity testing can only be done after birth. In fact, with the advancement of medicine, it can be done before the child is born. At this time, paternity testing can be done by drawing amniotic fluid, and the test results are exactly the same.

DNA (deoxyribonucleic acid) is the atomic substance of cells in the human body. Each atom has 46 chromosomes. In addition, the male sperm cell and the female egg each have 23 chromosomes. When the sperm and egg combine. These 46 atomic chromosomes create one life, so each person inherits half of the molecular material from his biological father and the other half from his biological mother.

DNA paternity testing is very different from traditional blood testing. It can be tested on different samples, including blood, buccal cells, tissue cell samples and semen samples. Because blood types, such as A, B, O or RH, are more common in the population, they are not as effective as DNA paternity testing in identifying each individual. Except for true twins, each person's DNA is unique. Because it is so unique, like a fingerprint, DNA is the most effective method for paternity testing.

Yes, with DNA testing, paternity testing can be done before the baby is born. DNA testing can be done through CVB placenta, usually between 10 and 13 weeks of pregnancy, or by amniocentesis within 14 to 24 weeks of pregnancy. Either procedure should be performed by an OB/GYN physician.

DNA is extracted from a few drops of blood, cheek cells, or cultured tissue fibers. The DNA sample is cut into small pieces using a dye and placed in a gel. The small pieces of DNA are pushed through an electrophoresis tank to separate them. The separated genes are placed on a nylon membrane and special DNA probes are used to search for the genes. The same genes will be condensed together, and then, using special dyes, the black barcode condensed by the DNA probes will be displayed under an X-ray environment.

The child's visible barcode is very special - half matches the mother's and half matches the father's. This process is repeated several times, with each probe being used to search for a different part of the DNA and to create a unique barcode. Using several different sets of probes, a paternity probability or resolution of more than 99.95% can be obtained.
