Hair Follicle Drug Testing - La Crosse, VA

What it is, How it works

Utilizing hair testing has emerged as a significant method for identifying drug and alcohol consumption. Hair acts as a record over time for alcohol and other substances by encapsulating biomarkers within the strands of hair as they grow. Gathering samples near the scalp, hair can offer up to a three-month detection timeframe for drugs and alcohol. Collecting hair is straightforward, not easily tampered with, and convenient to send.

A specimen measuring 1.5 inches with around 200 hair strands (comparable to a #2 pencil’s thickness) nearest to the scalp yields 100mg of hair, which is ideal for initial screening and confirmation tests. For EtG, additional tests, or for panels exceeding 10, it is advisable to collect 150mg of the sample. We advocate for using a jeweler’s scale to measure the specimen. Should scalp hair be unavailable, an equivalent quantity of body hair might be used. References to head hair pertain exclusively to scalp hair. Body hair includes other types, such as facial and axillary hair.

Process Overview

The laboratory examination of a drug test result consists of four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage where a sample is processed into a laboratory’s system, ensuring the sample was appropriately sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data entry not accomplished through an electronic chain of custody.

Screening serves as a preliminary assessment for substances of abuse. Though Screening is an economical method to dismiss drug usage for most samples, a positive result must be confirmed to hold up in legal proceedings. Any samples that present a tentative positive in Screening must undergo a secondary validation.

If a sample shows a tentative positive during Screening, additional hair from the original specimen is extracted for further analysis in the Extraction phase. Here, drugs are extracted from hair in smaller concentrations compared to other methods (such as urine or oral fluid), making hair drug analysis the most complex methodology to execute.

Any positive result from Screening is confirmed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples that show tentative positive results are washed before confirmation when necessary. The completeness of the laboratory process from Accessioning to Confirmation is verified under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests are capable of identifying drug usage for up to 90 days, contrasting with urine tests that provide a shorter detection span.
• Hard to manipulate: The rigidity of hair drug tests makes it exceedingly tough to manipulate, thus ensuring more precise results.
• Offers historical insights: It delivers an overview of drug consumption over time, not just recent usage.

Limitations:

• Incapable of detecting recent usage: It typically takes about 5-7 days for drugs to become detectable in hair.
• Expense: Generally, hair drug tests are pricier compared to other testing methods.
• Inconsistencies in outcomes: Elements like hair color and individual variances in hair growth might influence the levels of drug metabolites in hair.

Note: Frequently labeled as "hair follicle tests", the analysis itself focuses on the hair strand rather than the follicle beneath the scalp.
