Hair Follicle Drug Testing - Southwest San Gabriel Valley, CA

What it is, How it works

Hair testing is increasingly recognized as a robust method for identifying drug and alcohol consumption. By encapsulating biomarkers within the strands of growing hair, it offers an extended history of substance use. When sourced near the scalp, hair can serve to identify alcohol and drugs over a period of up to three months. Its collection is straightforward, modification is relatively challenging, and it is efficient to transport.

A 1.5-inch hair sample, comprising roughly 200 hairs (about the width of a #2 pencil), adjacent to the scalp yields 100mg, the optimal quantity for both screening and confirmation. For EtG, additional analyses, or tests exceeding 10 panels, a 150mg specimen is advisable. It's suggested to measure the specimen's weight with a jeweler’s scale. If scalp hair is unobtainable, an equivalent quantity of body hair can be gathered. "Head hair" strictly refers to scalp hair, while "body hair" encompasses all other types (such as facial, axillary, etc.).

Process Overview

The laboratory drug testing process comprises four critical stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves integrating a sample into the laboratory’s system initially. It ensures the sample's proper sealing and shipment, assigns a random LAN (Laboratory Accessioning Number), and completes any supplementary data entry absent from an electronic chain of custody system.

Screening provides an initial rapid assessment for abuse drugs. Though Screening serves as an economical measure to eliminate drug usage in most samples, a positive result must be validated for legal admissibility. Presumptively positive Screening samples necessitate a subsequent validation.

For samples indicated as positive during Screening, additional hair is withdrawn from the primary specimen for Extraction. At this stage, drug extraction from hair occurs at a significantly lower concentration than other methods (such as urine or oral fluid), making hair drug screening the most complex approach to implement.

Confirmation of any positive Screening outcome is achieved via GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positives undergo washing prior to confirmation if required. The complete laboratory workflow from Accessioning through to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair classification and within the accreditation of ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assays can identify drug use up to 90 days prior, unlike urine tests with a shorter detection window.
• Resistance to tampering: Cheating on a hair drug test is highly difficult, enhancing accuracy.
• Historical usage insights: Capable of illustrating a pattern of drug consumption over time, beyond just recent use.

Limitations:

• Inability to detect recent usage: Drugs take roughly 5-7 days to become detectable in hair.
• Cost: Hair drug assays tend to be more costly than alternative drug testing techniques.
• Result variability: Elements like hair color and personal hair growth differences can impact drug metabolite concentration in hair.

Note: Often termed "hair follicle tests", the analysis actually examines the hair strand, not the follicle underneath the scalp
