Hair Follicle Drug Testing - Coleville, CA

What it is, How it works

Hair testing is now recognized as an effective means for detecting drug and alcohol consumption. Hair captures lasting indicators of alcohol and drugs by embedding biomarkers within the strands as they grow. When sourced from near the scalp, hair samples can reveal drug and alcohol use within roughly a three-month timeframe. Hair collection is straightforward, generally tamper-resistant, and easy to transport.

A 1.5-inch hair sample, consisting of roughly 200 strands (similar in size to a #2 pencil), will yield 100mg of hair, which is optimal for both screening and verification. For EtG and tests exceeding 10 panels, 150mg of sample is advisable. We suggest using a jeweler’s scale for precise measurement. In the absence of scalp hair, equivalent body hair amounts can be collected. References to head hair specifically mean scalp hair. Body hair encompasses other hair types (such as facial, axillary, etc.).

Process Overview

There are four essential stages in the lab analysis of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of initially processing a sample into the lab's system. This step ensures the sample's proper sealing and shipping, assigns a unique LAN (Laboratory Accessioning Number), and completes any missing data entry not available through an electronic chain of custody.

Screening offers a preliminary assessment for substance use. While cost-effective for excluding drug use in most samples, a positive screen must be verified for legal acceptance. Samples testing presumptively positive during Screening require further confirmation.

Presumptive positives continue to Extraction, where additional hair from the original sample is processed. Here, drugs are isolated from hair at significantly lower concentrations than other tests (e.g., urine or oral fluid), highlighting the complexity of hair drug analysis.

GC/MS, GC/MS/MS, or LC/MS/MS are employed to confirm any positive screen results. Prior to confirmation, all presumptive positives undergo washing as necessary. The comprehensive process from Accessioning to Confirmation adheres to both CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 certifications.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests identify drug use for up to 90 days, unlike urine tests with shorter detection spans.
• Resistance to tampering: Hair drug tests are arduous to falsify, enhancing result accuracy.
• Chronological data: They indicate prolonged drug use patterns rather than recent consumption alone.

Limitations:

• Delayed detection: Drugs become apparent in hair around 5-7 days after use.
• Expense: Hair drug tests typically cost more than alternate testing methods.
• Result variability: Factors like hair color and personal hair growth differences can influence drug metabolite levels in hair.

Note: Although termed "hair follicle tests", these tests analyze the hair strand, not the follicle under the scalp.
