Hair Follicle Drug Testing - Brandywine, MD

What it is, How it works

Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. Hair retains a prolonged record of these substances by embedding biomarkers within the strands as they grow. When sourced near the scalp, the hair can offer up to an approximate three-month detection span for substances. This method is straightforward to collect, somewhat challenging to tamper with, and convenient for transportation.

A sample measuring 1.5 inches, consisting of approximately 200 hair strands (comparable to a #2 pencil), yields 100mg of hair, which is optimal for both preliminary screening and in-depth confirmation. For EtG, additional screenings, and tests exceeding 10 panels, a 150mg specimen is advised. It is recommended to weigh the sample using a jeweler’s scale. Should scalp hair be unavailable, a proportional amount of body hair may be taken. Note that 'head hair' specifically refers to hair on the scalp, while 'body hair' encompasses all other types (such as facial or axillary hair).

Process Overview

The laboratory analysis process of a drug test entails four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning signifies the sample's initial integration into the laboratory system, ensuring the sample is properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and handling any supplementary data entry absent in an electronic chain of custody system.

Screening involves a preliminary rapid test for substance abuse. While screening presents a cost-efficient method to dismiss drug use in the majority of cases, positive findings at this stage require further confirmation for legal admissibility. Samples yielding a tentative positive in Screening undergo secondary confirmation.

Should a sample elicit a presumptive positive in Screening, additional hair is extracted from the original sample and prepped for Extraction. This stage withdraws drugs from hair at a notably lower concentration than alternative methods (e.g., urine or oral fluid), rendering hair drug analysis the most challenging approach to execute.

Positive screening results are corroborated through GC/MS, GC/MS/MS, or LC/MS/MS. All samples suspected of positivity undergo washing prior to confirmation as necessary. The complete lab process from Accessioning through Confirmation is scrutinized following the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standard accreditation.

Advantages of hair drug testing:

• Extensive detection period: Hair drug assessments can discover substance use for a duration of 90 days, in contrast to urine tests which possess a shorter detection period.
• Challenge to manipulate: Manipulating a hair drug test is notably difficult, increasing the reliability of results.
• Provides chronological insight: It offers a record of substance use across time, beyond just recent usage.

Limitations:

• Incapable of detecting recent use: It requires approximately 5-7 days for drugs to appear detectable in hair.
• Expense: Generally, hair drug tests incur higher costs than other testing techniques.
• Result variability: Factors such as hair color and individual differences in hair growth can influence drug metabolite concentrations.

Note: Though commonly known as "hair follicle tests", the test scrutinizes the hair shaft rather than the follicle beneath the scalp.
