Who We Serve

Hair follicle drug testing fits a broad range of situations. Its 90-day detection window and tamper resistance make it a strong choice wherever a reliable record of drug use history matters.

Employers: Pre-employment screening, random testing programs, for-cause testing, and post-accident testing are all supported at our Addison location.
DOT-regulated Employers: We provide federal DOT drug testing compliance services for regulated industries.
Legal Professionals & Courts: Hair drug testing is commonly used in child custody proceedings, probation monitoring, and DUI or DWI matters in Texas. Most results from our facility are court-admissible.
Parents & Individuals: We serve individuals seeking personal testing with the same confidentiality and accuracy as any employer account.
Government Agencies & Schools: Our certified collectors and documented chain-of-custody process support institutional testing programs.

Texas has no mandatory drug testing statutes, but employers are encouraged to maintain a written drug-free workplace policy. Under Texas Labor Code Section 401.013(c), a positive drug test result may support a rebuttable presumption of intoxication in a workers’ compensation claim, and a positive result can affect unemployment eligibility when an employee is terminated for misconduct. We can help employers in Addison and the surrounding North Dallas area build and manage a compliant program from the ground up.

How Hair Drug Testing Works

Drugs and their metabolites enter the bloodstream after use and travel into the hair follicle, where they become embedded in the hair strand’s cortex as the hair grows. Our certified collectors take a sample of approximately 90-120 strands of hair, 1.5 inches in length, collected from the scalp. Despite being commonly called a hair follicle test, the process examines the hair strand itself rather than the follicle beneath the scalp.

Detection Windows

Head hair testing detects drug use within the past 90 days, based on average hair growth of roughly half an inch per month. If scalp hair isn’t sufficient, body hair can be used as an alternative sample source, extending the detection window to within the past year. Because drugs typically require approximately 7-10 days after use to appear in the hair shaft, very recent use may not yet be detectable.

Accuracy & Tamper Resistance

There are no known reliable methods of cheating a hair drug test, which makes it a strong choice for legal matters, zero-tolerance workplaces, and any situation where the integrity of the result matters. Initial screening uses an immunoassay method, and non-negative results are confirmed with Gas Chromatography-Mass Spectrometry (GC/MS) or Liquid Chromatography-Mass Spectrometry (LC/MS/MS) to reduce the likelihood of false positives before results are reported. Results are available in 1-2 days.

Hair drug testing can also be paired with a urine drug test to provide a comprehensive view of both recent and historical drug use, a combination many employers find valuable for pre-employment and for-cause situations.

Panel Options at Fastest Labs of Addison

We offer 5, 10, 12, 14, 16, and 18-panel hair drug tests. Standard panels screen for common illegal substances including marijuana/THC, cocaine, opiates and opioids, amphetamines and methamphetamines, and PCP. Expanded panels can cover additional controlled substances such as benzodiazepines, barbiturates, and methadone.

Employers can select the panel that aligns with their industry, company policy, or applicable regulatory guidelines. If your needs fall outside our standard options, additional substances can be tested depending on client requirements. Contact us to discuss the right panel for your program.

Hair Testing vs. Other Drug Testing Methods

Choosing the right testing method depends on your detection window requirements, turnaround needs, and intended use. Here’s how hair drug testing compares to the other methods we offer at Fastest Labs of Addison.

Hair Testing (90-Day Window): Detects drug use within the past 90 days. Results in 1-2 days. Tamper-resistant and well-suited for pre-employment screening, legal matters, and zero-tolerance policies. Body hair can extend the window to within the past year.
Urine Testing (Short-Term Window): Detects recent drug use with instant or 1-3 day results. Urine testing is the federally required specimen type for DOT-mandated programs, making it the required choice for regulated employers.
Saliva Testing (Recent Use): Effective for detecting very recent drug use. Results available instantly or within 1-3 days.
Nail Testing (Up to 6 Months): Provides a longer detection window among the methods we offer, covering up to approximately 6 months of drug use history. Lab results in 1-3 days.

Hair testing is a reliable option when employers or legal parties need insight into a pattern of drug use over time rather than just recent exposure. For the broadest picture, pairing hair testing with urine testing gives a comprehensive view of both past and recent use. Our team can help you determine which method or combination fits your specific situation.
