Hair Follicle Drug Testing - Farmington, MD

What it is, How it works

Hair analysis emerged as an influential method for identifying the presence of drugs and alcohol. Hair captures a historical record of substance use by embedding biomarkers within the hair's structure as it grows. When strands are cut near the scalp, they can reflect a detection period spanning up to about three months for drugs and alcohol. Collection of hair is straightforward, somewhat resistant to tampering, and easy to transport.

A sample measuring 1.5 inches consisting of around 200 hairs (similar to the thickness of a #2 pencil) nearest to the scalp amounts to 100mg, considered optimal for both initial screening and corroboration. For EtG, additional tests, or panels exceeding 10, it is advised to gather 150mg of hair. It's advisable to measure the weight using a jeweler's scale. In cases of absent scalp hair, a comparable collection of body hair is acceptable. References to head hair pertain exclusively to scalp hair, while body hair encompasses all other types (such as facial, axillary, etc.).

Process Overview

The primary steps in the lab analysis of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails recording a sample within a lab's framework. This step includes confirming the sample's integrity, allocating a random Laboratory Accessioning Number (LAN), and completing supplementary data entry lacking an electronic custody system.

Screening signifies an initial rapid assessment for illicit drugs. While Screening serves as a cost-efficient method to exclude drug presence in most samples, legal validation requires confirmation of any positive screens. Any samples initially found positive in Screening need a subsequent verification.

When a sample tests positive during Screening, additional hair is drawn from the initial set and readied for Extraction. During this phase, drugs are isolated from hair at minimal concentrations relative to other methods (e.g., urine or saliva), underscoring the complexity of hair drug testing.

Verification of any positive results from screening occurs through methods like GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all samples identified as presumptive positives undergo necessary cleansing. Every lab procedure from Accessioning through Confirmation is inspected under the CAP (College of American Pathologists) Hair designation and meets ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests reveal substance use for up to 90 days, whereas urine tests offer a shorter detection span.
• Difficult to evade: The complexity of falsifying a hair drug test increases the accuracy of results.
• Tracks historical usage: It delineates patterns of drug use over time, rather than just recent consumption.

Limitations:

• Incapable of detecting recent use: Drugs typically require 5-7 days to appear in hair after use.
• Expense: Hair drug tests are often costlier than alternative testing methods.
• Result variability: Factors like hair color and growth rate can influence the levels of drug metabolites detected in hair.

Note: Referred to as "hair follicle tests," the analysis is performed on the hair strand, not the follicle beneath the scalp
