Everything You Need to Know About DNA Testing

DNA testing Nashville is becoming more common these days. The sad part is, not many people are aware of the process of DNA and how it affects the purpose they get it for. And that’s why we are here to inform you about the most basic information about DNA testing.

Before we dig into details, let’s see what exactly is DNA.

DNA Testing Tests

DNA also known as Deoxyribonucleic Acid is the genetic ingredient contained by every cell of the human body. Every individual possesses a unique DNA. However, the same cannot be said about identical multiple births. Half of the DNA comes from your biological mother while the other half comes from your father. During DNA testing, those characteristics which does not match to your mother’s are inherited from your father.

Nashville drug testing is the precise and exact form of paternity testing possible. In case the DNA patterns of the child do not match to that of his alleged father on more than two probes, then the alleged father is not his/her biological father. In contrast to this, if the DNA patterns of the child match to those of his/her mother’s and father’s then the possibility of paternity is 99.9 percent.

What is the process for DNA testing?

This is the part where you need to pay the most attention. In case you need to undergo a DNA test, you must know how the mechanism works. DNA testing is a whole new level of science. The method of DNA testing can only be recorded in labs and requires specialized machinery.

Samples that can be used to collect DNA are as follows:

  • Hair
  • Mask
  • Hats
  • Weapons
  • Tools
  • Fingernails
  • Bedding
  • Dirty laundry
  • Cigarettes
  • Toothbrush
  • Toothpicks
  • Hairbrush
  • Facial tissue
  • Eyeglasses
  • Tape
  • Ligatures (rope, wire, cords)
  • Condoms
  • Envelopes and stamps
  • Saliva

Performing DNA Testing

As mentioned before, DNA testing can only be recorded in a lab with the required set of sophisticated machinery.

The next step is Lyse Cells. This process breaks down the complex membranes of the cell into simpler ones. Generally, it is performed by mixing an enzyme to a solution with the DNA sample.

After this stage, we proceed to extraction where the DNA is released from the cell.

This is followed by quantitation meaning to determine how much quantity of the DNA we need.

The next stage is called amplification where multiple copies of DNA are produced in order to characterize it.

Thereafter, separation is performed where the amplified DNA product is separated to allow subsequent identification. After this we have, analysis and interpretation where the quantitative and qualitative DNA samples are matched with the known profiles.

Last but not the least, quality assurance is ensured by sending the report to the analyst to ensure technical accuracy.

In case of a paternity DNA test, the potential father must match half of the child’s genetic DNA results. The other half comes from the mother. We hope you have found this article helpful in getting information about DNA testing.
