Hair Follicle Drug Testing - Johnson, WA

What it is, How it works

Hair testing is regarded as an effective instrument in identifying drug and alcohol consumption. Hair provides a comprehensive history of alcohol and drug usage by embedding biomarkers within the hair strand fibers as they grow. Hair samples collected from near the scalp can reveal approximately a 3-month detection period for alcohol and drugs. The collection of hair is straightforward, relatively challenging to tamper with, and simple to transport.

A sample of about 1.5 inches, containing 200 hair strands (comparable to the diameter of a #2 pencil) near the scalp yields 100mg of hair, which is optimal for screening and confirmation. For EtG, additional tests, or tests exceeding 10 panels, 150mg of sample is advised. Using a jeweler’s scale for specimen measurement is recommended. In the absence of scalp hair, an equivalent amount of body hair is an acceptable alternative. When mentioning head hair, it refers exclusively to scalp hair. Body hair encompasses all other hair types (e.g., facial, axillary).

Process Overview

The laboratory analysis sequence for drug test outcomes includes Accessioning, Screening, Extraction, and Confirmation.

In Accessioning, a sample undergoes initial processing into a lab’s system. This step ensures the sample is properly sealed and dispatched, assigns a LAN (Laboratory Accessioning Number), and completes any further data entry missing from an electronic custody chain.

Screening conducts an initial rapid assessment for drug usage. While a cost-efficient strategy to exclude drug use in most specimens, positive screens require confirmation for legal admissibility. Presumptive positives in Screening mandate a secondary verification.

For presumptive positives during Screening, additional hair is taken from the initial sample for Extraction. The process extracts drugs from hair at lower concentrations relative to other methods (such as urine or oral fluid), thereby making hair drug screening the most sophisticated testing approach.

GC/MS, GC/MS/MS, or LC/MS/MS methods validate any positive screening outcomes. Presumptive positive samples undergo washing before confirmation as needed. The entire lab process from Accessioning to Confirmation is evaluated under CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 norms.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests disclose drug use over up to 90 days, unlike urine tests that have shorter detection spans.
• Testing integrity: Hair drug tests offer high resistance to tampering, producing more precise results.
• Historical insight: They demonstrate drug use patterns over time rather than just recent activity.

Limitations:

• Detection delay: Drugs become detectable in hair approximately 5-7 days post-consumption.
• Expenses: Hair drug tests tend to be pricier compared to other methods.
• Result variability: Factors like hair color and individual hair growth differences can impact drug metabolite concentration in hair.

Note: Commonly labeled as "hair follicle tests", the analysis targets the hair strand itself and not the follicle beneath the scalp.
