Hair Follicle Drug Testing - Weldon, CA

What it is, How it works

Hair analysis is now recognized as an effective means for identifying drug and alcohol consumption. Hair strands capture biomarkers during growth, offering an extended timeline of alcohol and drug usage. By obtaining samples near the scalp, hair testing can yield a detection span of up to three months for alcohol and drugs. Hair collection is straightforward, hard to tamper with, and simple to send.

Collecting a 1.5-inch segment comprising roughly 200 hairs (comparable to a #2 pencil) nearest the scalp provides 100mg of hair, which is optimal for both screening and confirmation. For EtG tests, supplemental tests, and/or evaluations exceeding 10 panels, it is advised to collect 150mg. We suggest using a jeweler’s scale for accuracy. If scalp hair is not an option, equivalent body hair can be utilized. When mentioning head hair, we refer specifically to scalp hair. Body hair denotes other types (facial, axillary, etc.).

Process Overview

The laboratory analysis of a drug test result involves four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary integration of a sample into the laboratory’s system, ensuring it was securely sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any outstanding data entry absent from an electronic chain of custody system.

Screening conducts a cursory assessment for drugs. Although Screening serves as a cost-efficient approach for excluding drug use across most samples, a positive screening outcome mandates confirmation for legal acceptability. Samples testing presumptively positive require further confirmation.

In instances of a presumptive positive result during Screening, additional hair is retrieved from the primary specimen for Extraction. This phase involves isolating drugs from hair at significantly lower concentrations than found in other methods (e.g., urine or saliva), portraying hair drug testing as the most intricate approach.

Confirming any positive screening outcomes occurs through GC/MS, GC/MS/MS, or LC/MS/MS procedures. All samples with presumptive positives undergo washing before confirmation as necessary. The complete lab process from Accessioning through to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair classification and adherence to ISO / IEC 17025 criteria.

Advantages of hair drug testing:

• Extended detection period: Hair drug evaluations can recognize drug intake for up to 90 days, in contrast with urine tests that have reduced detection durations.
• Mitigated cheating capability: Overcoming a hair drug assessment is notably challenging, enhancing result accuracy.
• Conveys usage history: It reveals a drug consumption pattern over time, spanning further than recent use.

Limitations:

• Inability to identify recent consumption: Drug presence in hair becomes detectable roughly 5-7 days post usage.
• Expense: Hair drug assessments generally incur greater costs than other testing techniques.
• Result variability: Factors like hair color and individual hair growth discrepancies can influence drug metabolite levels in hair.

Note: Referred to as "hair follicle tests", the focus is on analyzing the hair strand itself, not the follicle below the scalp.
