Hair Follicle Drug Testing - Melville, LA

What it is, How it works

Hair testing is recognized as a potent method for detecting drug and alcohol consumption. Hair serves as a long-term recorder of alcohol and drug usage by encapsulating biomarkers within the growing hair strand. When clipped near the scalp, hair may deliver a detection window extending up to roughly 3 months for alcohol and drugs. Hair collection is straightforward, relatively resistant to tampering, and simple to transport.

A sample measuring 1.5 inches, consisting of around 200 hair strands (comparable to a #2 pencil width) adjacent to the scalp, will provide 100mg of hair, which is the preferred quantity for analysis and verification. For EtG, supplementary tests, and/or tests exceeding 10 panels, a 150mg sample is advisable. We suggest weighing the specimen using a jeweler’s scale. If scalp hair is unavailable, a similar quantity of body hair is suitable for collection. When referring to head hair, we specifically mean scalp hair. Body hair pertains to all other hair types (facial, axillary, etc.).

Process Overview

The laboratory procedure for processing a drug test result mainly involves Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into a lab's workflow. This step includes verifying sealing and shipping integrity, assigning a random LAN (Laboratory Accessioning Number), and completing supplemental data entry not covered by an electronic chain of custody system.

Screening is a preliminary assessment for drugs of misuse. Although Screening is an economical technique to exclude drug usage in most cases, a positive screen requires confirmation to be valid in a court setting. Any samples deemed presumptively positive during Screening warrant further confirmation.

When a sample is presumptively positive during Screening, additional hair is extracted from the original specimen for further preparation and Extraction. During Extraction, drugs are isolated from hair in much lower concentrations compared to other methods (e.g., urine or oral fluid), which contributes to the complexity of hair drug screening.

Confirmation for any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumed positive samples are washed as necessary before confirmation. The complete lab process, from Accessioning through Confirmation, is subject to review under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection range: Hair tests can uncover drug use for as long as 90 days, compared to the shorter span of urine tests.
• High resistance to manipulation: Cheating a hair drug test is extremely challenging, enhancing result accuracy.
• Historical data provision: It reveals patterns of drug usage over time, rather than only recent consumption.

Limitations:

• Incapability of detecting recent use: Drugs typically become detectable in hair after 5-7 days.
• Expense: Hair drug tests are generally costlier in comparison to other testing methods.
• Result variability: Factors such as hair pigmentation and individual hair growth differences may influence drug metabolite concentration in hair.

Note: Though often termed as "hair follicle tests", the assessment examines the hair strand and not the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing
