Hair Follicle Drug Testing - Hiles, WI

What it is, How it works

Hair analysis has emerged as a formidable method for detecting substances like drugs and alcohol. Hair retains a long-term record of substance use by sequestering biomarkers within the structure of the growing hair shaft. When taken from near the scalp, hair can offer a detection range of up to three months for substances such as alcohol. Hair is easy to gather, relatively tamper-resistant, and straightforward to transport.

A sample measuring 1.5 inches and consisting of approximately 200 hair strands (about the thickness of a #2 pencil) nearest to the scalp equates to 100mg of hair, which is the optimal amount for analysis and confirmation. For EtG, any supplementary tests, or panels exceeding 10, a 150mg quantity of the specimen is advised. We suggest using a jeweler's scale for accurate measurement. If hair from the scalp is not available, a comparable quantity of body hair may be used. When we reference head hair, it pertains solely to scalp hair. Body hair encompasses all other types of hair (such as facial and underarm hair).

Process Overview

The four primary stages in the laboratory handling of a drug screening include Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial intake of a specimen into the laboratory system. This process ensures the sample was correctly sealed and dispatched, assigns a unique LAN (Laboratory Accessioning Number), and completes any necessary data input absent in the electronic chain of custody.

Screening is an initial, superficial check for drug presence. Although Screening is economically efficient for excluding drug usage in most tests, a positive outcome must be confirmed for legal acceptability. Samples with presumptive positive results from Screening require subsequent validation.

If a sample appears positive during Screening, further hair is prepared from the initial sample for the Extraction phase. This phase involves isolating substances from hair at concentrations lower than those in other types of tests (e.g., urine or saliva), highlighting why hair drug tests are the most challenging to conduct.

Any confirmation of a positive screening result is performed through techniques such as GC/MS, GC/MS/MS or LC/MS/MS. All samples presumed positive undergo a cleansing routine before confirmation if necessary. The entire testing trajectory from Accessioning to Confirmation is scrutinized following both the CAP (College of American Pathologists) Hair category and ISO / IEC 17025 accreditation criteria.

Advantages of hair drug testing:

• Extensive detection timeframe: Hair analysis can identify drug use up to 90 days prior, unlike urine tests with shorter detection periods.
• Hard to falsify: Manipulating a hair drug test is notably difficult, enhancing result precision.
• Tracks historical use: This method can display a substance use pattern over time, beyond immediate consumption.

Limitations:

• Inability to detect recent use: It requires roughly 5-7 days post-exposure for drugs to be detectible in hair.
• Expense: Generally, hair drug assessments are costlier than alternative testing approaches.
• Result variability: Elements like hair color and personal differences in hair growth can impact drug metabolite levels in hair.

Note: Although termed "hair follicle tests", the analysis focuses on the hair strand rather than the follicle beneath the skin.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in Hiles, WI, trumps urine testing due to its superior detection accuracy. Unlike urine tests, hair samples offer a more reliable history of drug use.
