Hair Follicle Drug Testing - Edwards Afb, CA

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair captures a long-term record of substance use by integrating biomarkers in the hair's growing fibers. A sample taken near the scalp can reveal a detection span of up to approximately three months for alcohol and drugs. Hair collection is straightforward, relatively tamper-proof, and convenient to transport.

A 1.5-inch segment of around 200 hair strands (approximately the thickness of a #2 pencil) from nearest the scalp yields 100mg of hair, the optimal quantity for both screening and confirmation processes. For EtG, add-ons, and/or tests beyond 10 panels, it is advised to collect 150mg of the sample. Employ a jeweler’s scale for accurate measurement. If scalp hair isn't an option, an equivalent mass of body hair can be utilized. "Head hair" refers exclusively to scalp hair, while "body hair" denotes all other hair types (e.g., facial, axillary).

Process Overview

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

Accessioning involves initially entering a sample into the lab's system. This process ensures the sample's proper sealing and shipment, assigns it a random LAN (Laboratory Accessioning Number), and completes any missing data entry not already facilitated by an electronic chain of custody system.

Screening provides an initial rapid assessment for drug presence. While cost-effective for ruling out drug use in most samples, any positive results from Screening must be confirmed for legal admissibility. Presumptively positive samples during Screening undergo further confirmation.

Should a sample be presumptively positive during Screening, additional hair is taken from the original sample for Extraction. During Extraction, drugs are removed from hair at much lower concentrations compared to other methods (such as urine or oral fluid), which contributes to the complexity of hair drug testing.

Confirmation of any positive screens is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed before confirmation if necessary. The comprehensive lab process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage up to 90 days, unlike urine tests with a shorter detection range.
• Challenging to manipulate: Tampering with a hair drug test is very difficult, resulting in more dependable outcomes.
• Historical data provision: It offers a timeline of drug use over time rather than only recent consumption.

Limitations:

• Inability to detect recent usage: It takes roughly 5-7 days for drugs to be detectable in hair.
• Expense: Typically, hair drug tests cost more than other testing methods.
• Result variances: Factors like hair color and individual hair growth differences can influence drug metabolite concentration in hair.

Note: Though commonly termed "hair follicle tests," the analysis is performed on the hair strand itself, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing
