Hair Follicle Drug Testing - Oppelo, AR

What it is, How it works

Hair testing has emerged as a potent method for detecting drug and alcohol consumption. Hair encapsulates a prolonged history of alcohol and drugs by embedding biomarkers within its fibers as it grows. When collected near the scalp, hair offers approximately a 3-month detection range for alcohol and drugs. Hair collection is straightforward, somewhat resistant to tampering, and convenient for shipping.

A 1.5-inch section containing roughly 200 hair strands (similar in size to a #2 pencil) closest to the scalp yields 100mg of hair, which is the ideal amount for screening and confirmation. For EtG, additional tests, or panels exceeding 10, a 150mg sample is advised. It's best to weigh the sample using a jeweler’s scale. If scalp hair is not available, an equivalent volume of body hair can be used. When mentioning head hair, it specifically refers to scalp hair. Body hair refers to all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning begins with integrating a sample into the laboratory system, verifying proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing data entry omitted from the electronic chain of custody system.

Screening performs an initial rapid evaluation for potential drug use. Though cost-effective for excluding drug use in many samples, a positive screening requires confirmation for legal admissibility. Samples with presumptive positive results in Screening need further confirmation.

If a sample shows presumptive positivity during Screening, additional hair is retrieved from the original sample for Extraction. During Extraction, drugs are removed from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), contributing to the complexity of hair drug screening.

Any positive screening result is confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing before confirmation as necessary. The entire lab process, from Accessioning to Confirmation, is conducted under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection range: Hair drug tests can identify drug use up to 90 days, surpassing the shorter detection span of urine tests.
• Resistant to tampering: Cheating a hair drug test is very difficult, thus ensuring more reliable results.
• Shows historical patterns: It offers insights into drug usage patterns over time, not just recent consumption.

Limitations:

• Cannot capture recent usage: Drugs become detectable in hair only after approximately 5-7 days.
• Higher expense: Hair drug tests are often more costly than alternative testing methods.
• Result variability: Factors like hair color and personal hair growth rates can impact drug metabolite levels in hair.

Note: Although often termed "hair follicle tests," the analysis targets the hair strand and not the follicle beneath the scalp.
