Forensic DNA Testing

BLD Forensics Company offers a variety of Forensics DNA Analysis including collecting and processing DNA evidence from a crime scene and DNA comparison and Specimen matching using biological and non-biological samples. Our certified DNA laboratory is available to help law enforcement and the public with their Deoxyribonucleic Acid (DNA) testing to provide the most accurate and widely available technology available today. We process various DNA samples left behind at a crime scene, including hair, blood, saliva, semen, and skin cells. We can help match or eliminate suspects in crimes by seeing if their DNA samples match those found at the scene. We follow all chain of custody protocols to make sure the evidence will stand in a court of law, whether used by the defense or the prosecution team.

We offer genetic testing for various reasons, including identifying criminal situations like cases of rape and incest. We also provide forensic paternity/maternity tests to help identify missing victims or suspects using other family members available for testing. We can determine whether the victim is a relative, such as an aunt or uncle, grandparent, parent, sibling, or twin, using DNA testing procedures.

We offer various other DNA services, such as proof of infidelity for divorce court and child paternity tests for child support and custody cases. DNA samples can come from multiple sources, from a Buccal swab/FTA Card to a piece of clothing, toothbrush, razor, or hairbrush. We can identify biologicals such as blood, semen, urine, or sperm.

How does DNA testing work? DNA is a macromolecule that contains the main component of chromosomes. These components are shaped like a double helix and are usually found in the nucleus of a cell. No two people have the same DNA making it easy to identify whether two samples are from the same person or not.

Some ways DNA is used in a forensics lab:

  • The received specimen is used to conduct DNA analysis.
  • To give accurate comparisons for DNA analysis of items of criminal evidence.
  • Perform DNA typing tests on human tissues and body fluids to compare criminal evidence with samples of known origin.
  • To perform DNA extractions on various substrates, including bones, tissues, swabs, and blood samples.

There are several other things that DNA testing can identify. Using DNA testing, geogenic links with different populations from around the world can be uncovered.   DNA investigators can often find clues as to a victim’s health, age, race, and geographic area of origin, which can all be helpful when trying to figure out the identity or possible cause of a person’s death.

Our professional staff will provide an accurate written report of our findings to help law enforcement and other professionals understand what the evidence findings mean. Our experts can testify in court as to their results when needed. We stand behind the answers we find in the evidence 100% because we use only the most up-to-date testing and equipment.

The CSI or forensic investigator collects proof and evidence and collects traces of marks, which are a predominant factor in defining the crime suspect. Some mysterious cases take a long time to unfold. It is here that Forensics Investigations services in California are hired, and in most cases, the case is closed with the right identification being done.

The involved steps include gathering information; second is integration, and the third is the interview. It is commonly known as 3 I’s in the criminal scene set-up.

Yes, only a professional forensic investigator can carry the entire process. There is a long-sealed tape put up by the police at the crime spot. There is a golden rule which is followed. This implies that they do not touch or change anything in the place. Leave it as it is, and it is the job of a forensic investigator to conduct the entire process.
