Hair Follicle Drug Testing - Blair, WI

What it is, How it works

Hair assessments have gained recognition as an effective tool for identifying drug and alcohol consumption. Strands of hair offer a prolonged timeline of drug and alcohol exposure, capturing biomarkers within the fibers as hair develops. When garnered close to the base, hair can reveal up to about a 3-month detection period for drugs and alcohol. Hair is straightforward to gather, relatively resistant to tampering, and convenient to transport.

A segment measuring 1.5 inches with roughly 200 hair strands (equivalent to the diameter of a #2 pencil) closest to the scalp yields 100mg, which is optimal for screening and affirmation. For EtG, supplemental tests, and analyses exceeding 10 panels, a specimen weight of 150mg is advised. It's suggested to measure the specimen using a jeweler’s scale. If scalp hair is inaccessible, an equivalent volume of body hair may be used. Head hair refers exclusively to scalp hair, while body hair pertains to all other types (facial, axillary, etc.).

Process Overview

The laboratory work involved in a drug test result encompasses four crucial steps: Accessioning, Screening, Extraction, and Confirmation.

The Accessioning step entails the initial integration of a sample into a lab's system. This phase ensures the sample's proper sealing and dispatch, the allocation of a unique LAN (Laboratory Accessioning Number), and any extra data entry absent from an electronic chain of custody system.

Screening offers a preliminary assessment for controlled substances. Although Screening is cost-efficient for excluding drug use in most samples, any positive outcome necessitates confirmation for court validity. Samples that show presumptive positive results in Screening must undergo a secondary verification.

For samples yielding presumptive positives in the Screening phase, additional hair from the base sample is utilized in the Extraction stage. Here, drugs are extracted from hair in lower concentrations than other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug testing.

Any positive findings from Screening are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positive samples undergo washing before confirmation as required. The comprehensive lab process from Accessioning through Confirmation is audited under the CAP (College of American Pathologists) Hair criteria and conforms to ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Prolonged detection span: Hair drug assessments can catch drug use over a period of up to 90 days, as opposed to urine tests with shorter detection spans.
• Challenging to manipulate: The difficulty in cheating a hair drug test enhances the accuracy of results.
• Depicts historical usage: It outlines a pattern of drug consumption over time, beyond recent occurrences.

Limitations:

• Inability to identify recent usage: Drugs become detectable in hair approximately 5-7 days post-consumption.
• Expense: Hair drug tests tend to be pricier than alternative testing methods.
• Result variations: Elements such as hair color and individual differences in hair growth can influence the concentration of drug metabolites.

Note: Although often labeled "hair follicle tests", the analysis pertains solely to the hair strand, not the follicle beneath the scalp.
