Hair Follicle Drug Testing - Cearfoss, MD

What it is, How it works

Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged timeline of alcohol and drug intake by seizing biomarkers within its strands. Obtaining hair samples near the scalp can reveal a period of drug and alcohol use that extends up to around three months. Hair collection is straightforward, challenging to tamper with, and facilitates easy transportation.

An ideal sample consists of a 1.5-inch section of approximately 200 hair strands (equivalent to the circumference of a #2 pencil) taken closest to the scalp, yielding 100mg, which is optimal for screening and confirmation. For EtG, additional tests, and those beyond 10 panels, a sample of 150mg is advisable. Measuring the sample with a jeweler’s scale is recommended. If scalp hair cannot be retrieved, a comparable amount of body hair can be used. In this context, 'head hair' specifically refers to scalp hair, while 'body hair' encompasses other hair types (facial, axillary, etc.).

Process Overview

The drug testing laboratory process primarily consists of Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is initially entered into a lab's system. The procedure involves ensuring that the sample was properly sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and incorporating any supplementary data entry that an electronic chain of custody system did not capture.

Screening serves as an initial, expedient assessment for detecting drug abuse. While cost-efficient for negating drug use in most samples, a positive Screening result necessitates Confirmation for court admissibility. Samples with a presumptive positive in Screening inevitably require further confirmation.

If a Screening stage yields a presumptive positive, additional hair is extracted from the initial sample for Extraction. Here, drugs are isolated from hair at much lower concentrations than with other methods (e.g., urine or oral fluid), highlighting the complexity of conducting hair drug screenings.

Any positive screening must be validated using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as required. From Accessioning to Confirmation, the complete laboratory process is examined under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Detects drug use over an extended period: Hair drug tests can reveal drug consumption for up to 90 days, unlike urine tests that offer a shorter detection period.
• Hard to manipulate: The reliability of hair drug tests is high due to the difficulty in cheating them.
• Offers historical evidence: This method illustrates a timeline of drug usage over time, not just recent activity.

Limitations:

• Cannot determine recent consumption: Drug detection in hair requires approximately 5-7 days after use.
• Price: Hair drug testing tends to be more costly than alternative drug testing techniques.
• Result variability: Aspects such as hair color and individual hair growth rates might impact drug metabolite concentrations within hair strands.

Note: Commonly termed "hair follicle tests", the test actually evaluates the hair strand instead of the hair follicle beneath the scalp.
