Hair Follicle Drug Testing - Paul Spur, AZ

What it is, How it works

Hair testing is now regarded as an effective means for identifying drug and alcohol consumption. Hair captures a long-term record of alcohol and other drug use by embedding biomarkers in the structure of the growing hair strand. When obtained right from the scalp, hair offers a detection period of up to around 3 months for alcohol and other substances. Collecting hair is straightforward, fairly resistant to tampering, and convenient to transport.

A sample measuring 1.5 inches with about 200 hair strands (comparable to the size of a #2 pencil) closest to the scalp provides 100mg of hair, which is the optimal sample size for screening and confirmation. For EtG, additional tests, or tests exceeding 10 panels, a sample size of 150mg is suggested. It’s advisable to weigh the sample using a jeweler’s scale. If head hair is not accessible, an equivalent quantity of body hair can be used. When discussing head hair, it specifically means scalp hair. Body hair includes all other types of hair (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into the laboratory’s system. This step confirms the sample was sealed and delivered correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data entry not covered by an electronic chain of custody system.

Screening involves an initial rapid examination for drug use. Although Screening is a cost-friendly method to discount drug use in most samples, a positive screen requires confirmation for court admissibility. Samples that appear positive in Screening must undergo a secondary confirmation process.

If a sample displays positive indications during the Screening process, additional hair is extracted from the initial sample for Extraction. During Extraction, drugs are retrieved from hair in much lower concentrations compared to other methods (such as urine or oral fluid), which makes hair drug screening the most challenging technique to execute.

Confirmation of positive screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are considered presumptively positive are washed before confirmation as necessary. The full laboratory process from Accessioning to Confirmation is reviewed per both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which offer a shorter detection period.
• Hard to manipulate: Cheating a hair drug test is extremely difficult, resulting in more accurate results.
• Reveals usage patterns: It provides insight into drug use patterns over time, rather than just recent use.

Limitations:

• Recent use can't be detected: It typically takes 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests usually cost more than other drug testing techniques.
• Result variability: Variables such as hair color and individual hair growth differences can influence the concentration of drug metabolites in the hair.

Note: Although occasionally termed "hair follicle tests", the examination specifically analyzes the hair strand, not the follicle beneath the scalp.
