Hair Follicle Drug Testing - Winston, FL

What it is, How it works

Hair examinations have emerged as an effective means for identifying drug and alcohol consumption. Hair captures a long-term record of alcohol and drug use by embedding biomarkers within the strands of the growing hair. When obtained near the scalp, hair can deliver a detection window of up to roughly 3 months for alcohol and drugs. Hair collection is straightforward, hard to adulterate, and convenient to transport.

A 1.5-inch hair segment comprising roughly 200 strands (comparable to the circumference of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the ideal quantity for analysis and validation. For EtG, supplementary analyses, or tests exceeding 10 panels, a specimen amount of 150mg is advisable. We suggest measuring the sample using a jeweler’s scale. Should scalp hair be unavailable, an equivalent volume of body hair is acceptable. The term "head hair" specifically refers to scalp hair, whereas "body hair" denotes all other types (facial, axillary, etc.).

Procedure Outline

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

Accessioning entails the initial integration of a sample into the lab's system. This process includes ensuring the sample's proper sealing and transport, assigning an arbitrary LAN (Laboratory Accessioning Number), and finalizing any supplementary data recording absent from an electronic chain of custody protocol.

Screening constitutes an initial rapid assessment for substance abuse. Although Screening provides a cost-effective method to generally dismiss drug usage in most samples, a positive screen necessitates confirmation for legal admissibility. Samples deemed presumptive positive in Screening require further verification.

For samples identified as presumptive positive during Screening, additional hair is extracted from the original sample for preparation for Extraction. During this phase, drugs are isolated from hair at a significantly lower concentration compared to other methods (such as urine or oral fluid), which is why hair drug analysis is the most challenging technique to execute.

Validation of any positive screening outcome is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to validation, all presumptive positive samples undergo washing as necessary. The comprehensive laboratory procedure from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation criteria.

Benefits of hair drug testing:

• Extended detection period: Hair drug analyses can identify drug use for up to 90 days, in contrast to urine tests with a shorter detection window.
• Challenge to deceive: It is highly challenging to manipulate a hair drug test, leading to more accurate outcomes.
• Historical insight: It can reveal a pattern of drug use over time, beyond just recent consumption.

Drawbacks:

• Inability to detect recent consumption: Drugs require about 5-7 days to become identifiable in hair.
• Expense: Hair drug tests typically cost more than other drug testing approaches.
• Result variability: Elements such as hair color and individual growth differences can influence the levels of drug metabolites in the hair.

Note: While commonly termed as "hair follicle tests", the analysis targets the hair strand rather than the follicle beneath the scalp
