Hair Follicle Drug Testing - Pollock, LA

What it is, How it works

Hair assessments have gained recognition as an effective method for identifying substance and alcohol consumption. The fibers of growing hair strands ensnare biomarkers, providing an extended timeline of substance use. Hair, when collected near the scalp, offers a detection period extending to roughly three months for alcohol and other drugs. Collection is straightforward, tampering is relatively challenging, and shipment is convenient.

A 1.5-inch segment comprising roughly 200 hair strands (similar in size to a #2 pencil) nearest to the scalp yields approximately 100mg of hair, which is the optimal amount for both screening and verification. For EtG, add-ons, or analyses exceeding 10 panels, a sample of 150mg is advisable. We propose utilizing a jeweler's scale for precise measurement. Should scalp hair be lacking, body hair of equivalent mass might be obtained. Here, head hair implies strictly scalp hair, while body hair includes all other types such as facial and axillary hair.

Procedure Summary

The quartet of pivotal steps in lab processing of substance test outcomes encompasses Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the inaugural step of integrating a specimen into a lab’s system, ensuring correct sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and concluding any supplementary data input not supplied via an electronic chain of custody.

Screening serves as a preliminary examination for substances of misuse. Although Screening offers an economical method to dismiss substance use in most cases, a positive indication must be validated for legal admissibility. Any presumptively positive samples in Screening necessitate secondary confirmation.

Presumptively positive samples in Screening lead to additional hair extraction from the initial specimen, setting the stage for Extraction. In this phase, drugs are isolated from hair at significantly lower concentrations compared to other methods (like urine or oral fluid), highlighting why hair analysis poses the greatest methodological challenge.

Validation of any positive screening outcome is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. Samples presumed positive undergo a cleansing before confirmation as warranted. The entire laboratory sequence from Accessioning through Confirmation is scrutinized under the CAP (College of American Pathologists) Hair classification and compliance with ISO / IEC 17025 standards.

Benefits of hair analysis for substances:

• Extended detection timeframe: Hair tests can identify substance use for up to 90 days, surpassing the shorter detection span of urine tests.
• Resistance to falsification: Hair tests are notably resistant to deception, thereby enhancing result accuracy.
• Chronological data provision: They present a usage pattern over time, as opposed to merely recent usage.

Drawbacks:

• Inability to identify recent use: Detection in hair occurs approximately 5-7 days post consumption.
• Expense: Hair analyses generally incur higher costs than alternative methods.
• Result variability: Hair color and individual differences in hair growth can influence drug metabolite concentration within the hair.

Note: Frequently termed as "hair follicle tests", the actual examination pertains to the hair strand and not the follicle beneath the scalp.
