Experience Matters

What it is, How it works

Hair examination is recognized as an efficient approach for identifying drug and alcohol consumption. It offers an extensive record of alcohol and drug use by trapping identifiers in the structure of the developing hair. Hair collected near the scalp can indicate drug and alcohol usage for up to three months. The collection is straightforward, tampering is relatively challenging, and the samples are easy to send.

A haircut sample of approximately 1.5 inches, involving around 200 hair strands (comparable to the girth of a #2 pencil), taken close to the scalp can provide 100mg, the preferred amount for preliminary and confirming tests. For EtG, additions, and/or tests exceeding 10 panels, 150mg is advisable. Utilizing a jeweler’s scale for specimen weighing is suggested. If no scalp hair is present, an equivalent mass of body hair can be gathered. By head hair, we indicate solely scalp hair. Body hair signifies any other hair (such as facial, underarm, etc.).

Process Overview

The lab analysis of a drug testing sample comprises four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first phase where a sample is logged into the lab's system, ensuring that it was properly sealed and delivered, assigning a random LAN (Laboratory Accessioning Number), and finishing any lacking data entry from the electronic chain of custody system.

Screening, a primary evaluation for drugs, is a cost-effective means to exclude drug presence. However, to be used legally, any positive outcome from the Screening must undergo Confirmation. Any samples indicating potential positivity in Screening require additional confirmation.

In cases where Screening suggests a positive result, additional hair is extracted from the initial sample for the Extraction phase. This phase separates drugs from hair at a lower concentration compared to other methods (e.g., urine or saliva), rendering hair drug testing the most complex method.

Confirmation of positive Screening outcomes is executed with GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating probable positivity are cleansed before confirmation, if necessary. The whole lab process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair categorization along with ISO / IEC 17025 standard accreditation.

Advantages of hair drug testing:

  • Extended detection period: Hair drug assessments can identify drug use up to 90 days prior, unlike urine tests which cover a shorter timeframe.
  • Challenging to manipulate: Executing a hair drug test is hard to cheat, ensuring more reliable results.
  • Presents historical insights: It shows a pattern of drug consumption over time, not solely recent use.

Limitations:

  • Inability to reveal recent use: Drugs typically appear in hair after 5-7 days.
  • Expense: Generally, hair drug assessments are pricier than other testing techniques.
  • Result variations: Factors like hair color and individual growth patterns can alter the drug metabolite concentration in hair.

Note: Often named "hair follicle tests", these examinations test the hair strand itself, not the hair follicle beneath the scalp.
