What Qualifies as Court Admissible DNA?

Court admissible DNA is the result that you can present in court as a form of evidence. Juries and lawyers consider DNA to be a reliable source of evidence. Under certain circumstances, this type of evidence can be undeniable and an integral part of a case. Court admissible DNA should meet  certain legal standards and procedures, as the court will not accept a test if it doesn’t fulfill specific legal requirements. Matters like parental dispute, child custody, and immigration often require court admissible DNA tests. You may also need court admissible DNA in more extreme matters like violent crimes.

What is DNA?

DNA is a molecule that makes up the chromosome cells in our body. You can consider it as a building block for all living beings. It consists of nucleotides that bind together to form a genetic code, which is an essential part of who you who you are. What’s more, the DNA’s binding makes a double helix, ladder like structure. The genetic codes follow a similar pattern, which helps scientists  identify certain characteristics, traits, physical appearance, and medical conditions of a person. Furthermore, DNA molecules bind with each other in the form of a strand.

DNA Evidence

DNA evidence can be immensely helpful in court. In order to test DNA, you need a sample, which can be obtained quite easily  . A sample can come from any part of the body. When it comes to crimes, even a criminal’s fingerprints can leave genetic information for forensic specialists to decode. In other cases that involve child custody or immigration, you can collect reliable samples. A doctor normally extracts cheek cells from a swab for accurate results.

The Development of Forensic DNA Evidence

The use of DNA in profiling individuals did not exist until the mid 1980’s. An English Scientist, Alec Jeffrey discovered that certain areas in the DNA molecule strand contain patterns that seem to repeat quite often. These repetitions are distinctive to each individual, except for identical twins who share the exact same DNA. Dr Jeffrey was then able to discover a test that measures the variations of these repeated patterns in order to identify individuals. This was the first technique that compared samples of the DNA in order to profile individuals. People knew it as Restriction Fragment Length Polymorphism. (RFLP)

This method is very accurate and reliable, but it requires a large amount of DNA samples. People now use Polymerase Chain Reaction method. (PCR), as it allows them requires a very small amount of DNA.

Admissibility in Court

Many circumstances can affect the admissibility of DNA evidence in court. The courts demands immense accuracy when it comes to DNA methods. They can also ask for more than one method to ensure the DNA evidence is accurate. In some cases, judges may demand a scientific approach in order to mitigate the varying degrees of results. Mistakes like contamination, errors in the chain of custody, transport and storage can ultimately hamper the integrity of the DNA results. It could lead to the court dismissing DNA evidence because of its vagueness.

How to Reduce Risks

Maintaining admissibility of DNA evidence includes the following steps.

Avoid Contamination

It’s very important to not tamper with the DNA evidence. Consider keeping it in a safe and secure place so it has no contact with any external sources that could contaminate it. This will make sure it comes in handy during trials. .

Chain of Custody

Documentation of the DNA evidence is very important. The lesser the people handle the evidence the better. A long chain of custody handling DNA evidence could lead to intentional or unintentional tampering. Therefore, it would be best to ensure that only a select few people are responsible for handling the evidence.

What Makes a Paternity Test Court Admissible

Many factors can make a paternity test court admissible. For example in cases of child custody, if the child gets really sick. Their treatment can require paternal DNA tests in order to find out the ethnic heritance of the parents, since this information can be crucial for treatment.

Other cases may include immigration processes where a person needs to travel and their parents already reside in the desired country. The court may require you to provide a DNA test if you wish to travel on an invitation. It will prove whether there is a  biological relationship between you and the other party. The immigration office accepts DNA tests form labs accredited by the AABB.

What is in a DNA Testing Lab?

What is in a DNA testing lab? A scientist’s laboratory equipment is their toolset. If they do not have that equipment, they cannot perform DNA testing. The choice of testing equipment depends on the laboratory and the method they use for testing. Different laboratories may use different techniques. Some equipment is compulsory for a laboratory, and some are not so important, so they have alternatives. The most common items that almost every laboratory has:

  • Glassware
  • Hot plates
  • Shakers
  • pH meters
  • Pipettors
  • Fume hoods
  • Analytics balances
  • Incubators
  • Freezers
  • Computers
  • Plasticware
  • Various types of microscopes

Some specialized laboratories may also include cell culture, autoclave, or tissue culture, PCR machine or thermocycler, spectrophotometer, etc. However, if a laboratory conducts advanced research, they will have:

  • Histology equipment,
  • Surgical instruments
  • Microtomes
  • Imaging systems
  • A flow cytometer
  • Histology equipment
  • Electrophysiological equipment (such as analysis software, pipette pullers, and patch-clamp amplifiers)
  • DNA sequencing equipment.

Complete Process of DNA Testing

When undergoing DNA testing for any reason, you may be confused about the procedure of how laboratory professionals conduct the testing. DNA testing is a scientific technique. To perform DNA testing, professionals need specialized machinery and a laboratory. Below, you will learn about the DNA testing process:

1.    Collection of Samples

The sample can be your hair or any bodily fluid, as these elements contain DNA. Usually, laboratories gather testing samples through a swab by inserting it inside the mouth to the cheek. This method is the buccal smear and is the least invasive and common method for collecting samples.

2.    Lyse Cells

In this process, the professionals will break down the cell membrane from the sample. They do so by adding an enzyme in the solution containing DNA samples.

3.    Separation

To separate the DNA, professionals use different ways. Electrophoresis is the most common process. In this method, molecules will sort through the electric field. DNA has a molecular structure, so it will separate from the sample.

4.    Copying

To make copies of the DNA, professionals rely on the PCR process. After that, they use these copies to test for genetic markers.

5.    Testing

In this step, they identify genetic markers from the DNA to discover the relationship. DNA has thousands of genetic markers that we recognize. However, only 16 to 21 genetic markers can report the relationship to prove genetic relationships.

6.    Matching

After obtaining the markers, professionals match it with the unknown DNA samples. This will highlight that the DNA donor and the unknown person are the same or not. For paternity DNA testing, only half of the DNA will match the mother. The remaining half comes from the father.

So after receiving the samples, technicians will identify the proteins, chromosomes, and DNA according to the suspect’s disorders. After the testing is complete, they will share the result with the genetic counselor, doctor or the immigration office in reference to the person. They can also send the results directly to the person on request.

For the screening tests of the newborn, doctors take a small sample of the blood by pricking the heel of the baby. However, in this test, the lab only shares the results with the parents if it is positive. Once the test is positive, professionals will perform various tests to find out any genetic disorder that the newborn may carry.

If you are the person taking the test, you need to understand the DNA testing process, the limitations and benefits of the testing, and the consequences that may occur after receiving the results. The process of educating a person taking a DNA test and asking for their permission is informed consent.


People need DNA testing for various purposes, such as half or full sibling test, maternity or paternity testing, or to prove their relationship through immigration DNA testing. Regardless, our professional and friendly staff can help every step of the process. Our experts can also support you in a situation where you are born abroad and do not have any citizenship.
