Hair Follicle Drug Testing - Centralia, IA

What it is, How it works

Hair testing has gained recognition as a significant method for detecting drug and alcohol usage. Hair captures a long-term substance history by embedding biomarkers in the fibers of an expanding hair strand. When cut close to the scalp, the hair may reveal up to about a 3-month detection period for drugs and alcohol. It is easy to gather hair, tough to tamper with, and hassle-free to dispatch.

A 1.5-inch segment of roughly 200 hair strands (similar in thickness to a #2 pencil) nearest to the scalp yields around 100mg of hair, which represents an ideal quantity for assessment and verification. For EtG, supplemental, and/or analyses exceeding 10 panels, 150mg of the sample is advisable. It's a good practice to measure the sample using a jeweler’s balance. Should scalp hair be absent, a comparable measure of body hair can be collected. Mentioning head hair pertains solely to scalp hair. Body hair encompasses all other hair varieties (facial, axillary, etc.).

Process Overview

The four primary processes involved in lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of the preliminary procedure of a sample entry into a lab's records. This involves affirming the sample's seal was intact and properly dispatched, assigning it a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry absent in an electronic chain of custody system.

Screening provides an initial rapid assessment for substance usage. Despite Screening's efficiency in dismissing drug presence in most samples, a favorable screen necessitates confirmation for court admissibility. Samples that indicate positive in Screening require secondary verification.

Should a sample test positive in the Screening phase, additional hair is drawn from the initial collection and gets prepared for Extraction. Here, substances are segregated from hair at a significantly lower density than other techniques (e.g., urine or oral fluid), which justifies why hair drug testing is sophisticated to execute.

Confirmation of any positive screening result occurs via GC/MS, GC/MS/MS or LC/MS/MS. Presumptive positive samples undergo a wash prior to confirmation when required. The entire lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair specification and the accreditation to ISO / IEC 17025 criteria.

Advantages of hair drug testing:

• Extended detection period: Hair drug analyses can identify drug use for nearly 90 days, compared to urine evaluations which have a reduced detection window.
• Challenge to defraud: It is notably challenging to defraud a hair drug exam, thus enhancing result accuracy.
• Offers historical insight: Displays a substance use trend over a duration, not just recent usage.

Limitations:

• Incapable of recent use detection: It typically takes about 5-7 days for drugs to become traceable in hair.
• Expenses: Hair drug assessments are usually pricier than alternative drug testing strategies.
• Result variations: Elements such as hair pigmentation and individual hair growth differences can influence the concentration of drug metabolites in hair.

Note: While often labeled as "hair follicle tests", this exam actually evaluates the hair strand rather than the follicle beneath the scalp
