Hair Follicle Drug Testing - Cressey, CA

What it is, How it works

Hair assessments are recognized as effective instruments for identifying alcohol and drug consumption. The hair records a prolonged history of substances by capturing biomarkers within its expanding fibers. When retrieved adjacent to the scalp, hair can reveal up to a three-month discovery period for substances. Hair is hassle-free to gather, relatively tamper-resistant, and straightforward to transport.

A 1.5-inch segment comprising roughly 200 hair strands (comparable to a #2 pencil) nearest the scalp offers 100mg of hair, which is optimal for assessment and verification. For EtG, additional tests, and/or assessments above 10 panels, 150mg of the sample is advisable. We suggest measuring the sample on a jeweler's scale. Should scalp hair be missing, an equivalent volume of body hair may be gathered. When mentioning head hair, it pertains solely to scalp hair. Body hair indicates all other varieties (facial, axillary, etc.).

Process Overview

The principal phases in laboratory analysis of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary handling of a sample within a laboratory's framework. This process involves validating the sample's proper sealing and dispatch, allocating a random LAN (Laboratory Accessioning Number), and finalizing any supplemental data recording absent in an electronic chain of custody system.

Screening comprises an initial rapid inspection for substance misuse. Although Screening is an economical approach to exclude drug usage in most samples, a positive Screening result necessitates confirmation for court admissibility. Samples showing a presumptively positive result in Screening call for a subsequent confirmation.

Upon a presumptive positive outcome during Screening, additional hair is extracted from the initial sample for the Extraction process. Here, drugs are retrieved from hair at considerably lower concentrations compared to other methods (such as urine or oral fluid); hence, hair drug Screening is recognized as the most challenging technique to execute.

Any positive Screening result is confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as required. The entire laboratory operation from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long detection span: Hair drug evaluations can identify drug intake for up to 90 days, unlike urine tests which have a reduced detection span.
• Challenging to falsify: It is exceedingly tough to deceive a hair drug test, resulting in more accurate findings.
• Offers historical insight: It can display a drug usage pattern over time, not solely recent consumption.

Limitations:

• Cannot identify recent intake: Drugs become discernible in hair approximately 5-7 days following consumption.
• Expense: Hair drug evaluations are typically costlier than other drug testing techniques.
• Inconsistencies in findings: Elements such as hair pigmentation and individual differences in hair growth can influence metabolite concentrations in hair.

Note: Although often termed "hair follicle tests", the assessment genuinely analyzes the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing
