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.
