DNA Testing


What happens at the collection site?
Parties will be required to present a photo ID at the time of collection (i.e. driver’s license, passport, birth certificate). A Chain of Custody form will be completed, requiring signatures and photographs of parties in the case. A legal guardian’s signature will be required for any minors.

What is a buccal swab collection?
DNA samples are collected by gently rubbing the inside of the mouth using a non-invasive, cotton-tipped swab (buccal swab). Epithelial (cheek) cells adhere to the swab. Once collected, each swab is marked with the party’s identification and sent to the lab for testing.

What happens with DNA samples once they are received by the DNA testing laboratory?
When DNA samples are received in the laboratory, the Chain of Custody form is signed by our lab staff.  Each sample is inspected and entered into the laboratory database.  A case is created to evaluate the questioned relationship.  DNA testing of the samples begins promptly upon receipt in the laboratory.

DNA Sample Testing

The samples are processed in a laboratory specifically designed for DNA testing.

Each sample is processed in duplicate.

Robots are used to provide consistency to the testing and quality results.

The DNA profile generated is reviewed by trained technicians.

The analysis of DNA results is then performed.

The results are electronically submitted to F&R Services, LLC.

F&R Services, LLC forwards the testing results to its clients.

Urine Screening


Drug testing aims to filter drug users from the workplace as well as to deter drug use on the job. Urine testing is the most common screening method and detects recent use, typically in the previous one to three days. Urine testing is suitable for all testing reasons – from pre-employment to random to post-accident – and can be performed for a wide range of illicit and prescription drugs. 

While a positive urine test does not necessarily mean that an individual was "under the influence" at the time of the test, it has become the standard for evidence of "current use" for the U.S. Department of Labor. Urine testing is also the only method allowed for federally mandated tests.

Urine testing requires a minimum of 30 mL of urine (45 mL for a DOT collection) collected in the privacy of a restroom. The collector pours the specimen into a bottle that is sealed with tamper-evident tape. The specimen and completed Custody and Control Form (CCF) are sent to the laboratory for screening.

Hair follicle testing


Hair Testing for a 90-Day Drug Use History

Hair Follicle Testing for drugs is one of the only ways to get an in depth assessment of up to 90 days in the past to determine if someone has been using drugs. This is a great test for an employer or parent.

Simple specimen collection and highly accurate results that meet the same reference standards as urine testing. In addition, there are no known methods for sample adulteration (hair washing will not dilute the sample). Because specimen collection can be directly observed, the risk of adulteration is even further reduced.  This is an excellent test for pre-employment drug testing!

We get the results back to you quicker: Negative results are reported within 24 hours of receipt at the laboratory, and positive results are confirmed using gas chromatography/mass spectrometry (GC/MS) or gas chromatography/mass spectrometry/mass spectrometry (GC/MS/MS) within 48 to 72 hours. Hair testing is also forensically defensible.

When compared with urine specimen testing, hair testing provides up to 2.5 times the number of positives and a longer detection window. Hair testing can test for the following classes of drugs:

  • Amphetamines (including Ecstasy)
  • Cocaine
  • Marijuana
  • Opiates
  • Phencyclidine (PCP)
