Hair Follicle Drug Testing - Mira Loma, CA

What it is, How it works

Hair analysis has emerged as a robust resource for detecting drug and alcohol usage. Hair offers a prolonged history of alcohol and other substances by securing biomarkers within the strands of growing hair. If gathered near the scalp, hair samples can provide nearly a three-month timeframe for identifying alcohol and other substances. Hair samples are straightforward to gather, relatively hard to tamper with, and convenient to transport.

A 1.5-inch section of around 200 hair strands (similar to the width of a #2 pencil) closest to the scalp provides 100mg of hair, the optimal amount for screening and confirmation. For EtG, additional tests, and/or assessments beyond 10 panels, 150mg of the sample is advised. We suggest measuring the sample on a jeweler’s scale. If scalp hair is not available, an equivalent quantity of body hair can be collected. When mentioning head hair, it refers exclusively to scalp hair. Body hair includes all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the introductory handling of a sample into a lab’s system. This step includes confirming the sample was properly sealed and transported, issuing a random LAN (Laboratory Accessioning Number), and finalizing any additional data input not conducted by an electronic chain of custody system.

Screening involves an initial rapid assessment for drugs of abuse. Although Screening is a cost-efficient method to exclude drug use in most samples, a positive screen requires confirmation to be court-admissible. Any samples that are tentatively positive in Screening necessitate a secondary confirmation.

If Screening indicates a presumptive positive, further hair is extracted from the initial sample for the Extraction phase. In this stage, drugs are removed from hair at a notably lower concentration than other methods (e.g., urine or oral fluid). Consequently, hair drug screening is considered the most challenging methodology.

Confirmation of any positive screening outcome is carried out via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed before confirmation, as required. The complete laboratory procedure from Accessioning to Confirmation is audited according to both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection timeframe: Hair drug tests can identify drug usage for up to 90 days, unlike urine tests with shorter detection periods.
• Difficult to manipulate results: Altering hair drug test results is quite challenging, ensuring more accuracy.
• Historical usage data: It illustrates a drug usage pattern over time, rather than just recent usage.

Limitations:

• Cannot identify recent use: It typically takes 5-7 days for drugs to become detectable in hair.
• Cost issues: Hair drug tests tend to be more costly than alternative drug testing approaches.
• Result variability: Factors including hair color and individual hair growth variations can influence the concentration of drug metabolites in hair.

Note: Although frequently called "hair follicle tests," the actual analysis targets the hair strand and not the hair follicle beneath the scalp.
