Hair Follicle Drug Testing - Merrillan, WI

What it is, How it works

Hair analysis has increasingly become seen as a robust option for detecting drug and alcohol consumption. Hair can encapsulate a long-term record of alcohol and other substances by embedding biomarkers in the strands of growing hair. When sampled near the scalp, hair provides nearly a three-month detection period for alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and simple to transport.

A sample measuring 1.5 inches, consisting of roughly 200 hairs (around the size of a #2 pencil) nearest the scalp, yields 100mg of hair, which is the optimal amount for screening and confirmation. For EtG, additional tests, or analyses above 10 panels, 150mg of the specimen is advised. We suggest measuring the sample on a jeweler’s scale. If scalp hair isn't available, an equivalent quantity of body hair can be used. When mentioning head hair, we specifically mean scalp hair. Body hair includes all other hair types (facial, axillary, etc.).

Process Summary

The key steps in processing a drug test in the lab are Accessioning, Screening, Extraction, and Confirmation.

Accessioning handles the initial integration of a sample into a lab's process. This stage involves ensuring the sample was appropriately sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not already covered by an electronic chain of custody.

Screening involves an initial rapid assessment for drugs of concern. Screening remains a cost-efficient method to eliminate drug usage for the majority of samples, however, to be court-admissible, a positive screening requires confirmation. Any samples that screen as presumptively positive mandate a subsequent confirmation.

Should a sample screen as likely positive, further hair is taken from the initial collection and prepped for Extraction. During this phase, drugs are isolated from hair at considerably lower concentrations than through other methods (e.g., urine or saliva), making hair drug analysis the most challenging method to execute.

Positive screening results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples presumed positive are cleansed before confirmation if necessary. The full lab process, from Accessioning to Confirmation, is examined under CAP (College of American Pathologists) guidelines for Hair as well as the ISO / IEC 17025 accreditation standards.

Benefits of hair drug testing:

• Spanning detection period: Hair drug tests can trace drug use over a duration of up to 90 days, whereas urine tests offer a briefer window.
• Enhanced security: It is very hard to manipulate a hair drug test, resulting in more reliable findings.
• Chronologically informative: Offers insights into drug usage patterns over time, rather than merely recent use.

Drawbacks:

• Cannot detect recent use: Drugs become detectable in hair approximately 5-7 days post-use.
• Expense: Hair drug testing tends to be costlier compared to other testing techniques.
• Result variability: Variables like hair color and personal differences in hair growth can influence drug metabolite levels in hair.

Note: Although often termed "hair follicle tests", the analysis assesses the hair strand, not the follicle beneath the scalp.
