Hair Follicle Drug Testing - King City, CA

What it is, How it works

Hair evaluations have emerged as an effective mechanism for identifying alcohol and drug consumption. Hair serves as a chronological record of alcohol and other drug usage by encapsulating biomarkers within the strands of growing hair. When obtained near the scalp, it can provide a detection period of up to roughly three months for both alcohol and various drugs. Collection of hair is straightforward, somewhat tamper-resistant, and simple to transport.

An ideal screening and confirmation hair sample consists of a 1.5-inch section of roughly 200 hair strands (comparable in size to a #2 pencil) nearest the scalp, providing about 100mg of hair. For EtG, additional tests, and/or panels exceeding 10, a 150mg specimen is advisable. Specimen measurement using a jeweler’s scale is recommended. If scalp hair is not available, an equivalent body hair amount can be collected. When discussing head hair, it specifically refers to scalp hair, while body hair encompasses all other types (like facial or axillary hair).

Process Overview

The fundamental stages in a laboratory's drug testing process include Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial integration of a sample into the laboratory's framework, which includes confirming that the sample was correctly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry not facilitated by a digital chain of custody system.

Screening serves as a preliminary assessment for substances of abuse. Although Screening provides an economical means to rule out drug use in most samples, any positive reading must be corroborated for legal acceptance. Samples indicated as presumptive positives in Screening necessitate secondary verification.

For presumptive positives identified in Screening, more hair is extracted from the initial sample and readied for Extraction. In this phase, drugs are drawn from hair at much lower concentrations than other methods (e.g., urine or oral fluid), highlighting why hair drug screening represents a complex methodology.

The Confirmation of positive screening outcomes is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples considered presumptive positives are cleansed prior to confirmation where required. The entirety of the laboratory's process from Accessioning through Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection interval: Hair drug testing can trace drug ingestion for up to 90 days, unlike urine testing which has a more limited detection window.
• Resistance to manipulation: Cheating a hair drug test is exceedingly difficult, enhancing result accuracy.
• Historical usage data: It can provide insight into drug usage patterns over time, not merely recent activity.

Limitations:

• Inability to detect immediate consumption: Detection of drugs in hair requires approximately 5-7 days post-use.
• Expense: Hair drug testing is typically pricier compared to alternative testing methodologies.
• Result variability: Variables such as hair pigment and individual hair growth rates may influence drug metabolite concentrations in the hair.

Note: The term "hair follicle tests" is a misnomer, as the analysis focuses on the hair strand, not the follicle beneath the scalp.
