Hair Follicle Drug Testing - White Hall, MD

What it is, How it works

Hair analysis has emerged as a potent mechanism for identifying drug and alcohol consumption. Hair captures a prolonged timeline of alcohol and drug exposure by encasing biomarkers within the strands as they grow. When clipped near the scalp, hair offers roughly a 3-month retrospective window for detecting alcohol and drugs. Hair is easy to gather, somewhat resistant to tampering, and straightforward to dispatch.

An ideal screening and confirmation require a 1.5-inch sample of about 200 strands (similar in diameter to a #2 pencil) nearest to the scalp, providing 100mg of hair. For EtG, add-ons, and tests exceeding 10 panels, 150mg of the sample is advisable. It's suggested to gauge the sample on a jeweler’s scale. In the absence of scalp hair, a proportional amount of body hair can be taken. When mentioning head hair, we specifically refer to scalp hair. Body hair encompasses all other varieties (facial, axillary, etc.).

Process Summary

The four primary phases in processing a drug test result in a lab are Accessioning, Screening, Extraction, and Confirmation.

Accessioning starts with the sample's entry into a laboratory’s system. This phase involves ensuring the sample was properly sealed and transported, issuing a random LAN (Laboratory Accessioning Number), and completing any additional information not covered by an electronic chain of custody setup.

Screening entails an initial swift evaluation for misuse of drugs. While Screening is a cost-effective approach to dismissing drug use in most samples, a positive indication requires confirmation for legal acceptability. Any samples preliminarily positive in Screening must undergo secondary confirmation.

If a sample appears positive during Screening, additional hair is taken from the initial collection and readied for Extraction. During Extraction, drugs are retrieved from hair at a substantially lower concentration than other methods (e.g., urine or oral fluid), making hair tests the most challenging method to execute.

Confirmation of any positive screening results is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. Any suspect positive samples are cleaned before confirmation if necessary. The entire lab process from Accessioning to Confirmation complies with both the CAP (College of American Pathologists) Hair designation and the standards of ISO / IEC 17025 accreditation.

Benefits of hair drug analysis:

• Extended detection period: Hair analyses can identify drug usage for up to 90 days, unlike urine tests which have a shorter span.
• Hard to manipulate: Cheating a hair drug test is extremely tough, thus ensuring more precise results.
• Historical insight: It can depict a pattern of drug consumption over time rather than just recent use.

Drawbacks:

• Cannot identify recent use: Drugs take roughly 5-7 days to become detectable in hair.
• Expense: Hair analyses typically cost more than alternative drug testing methods.
• Result variations: Factors like hair color and individual hair growth differences can impact drug metabolite concentration in hair.

Note: Although frequently termed "hair follicle tests," the examination targets the hair strand, not the follicle beneath the scalp.
