Hair Follicle Drug Testing - Los Altos Hills, CA

What it is, How it works

Hair testing is increasingly recognized as an effective method for detecting drug and alcohol use. The fibers of a growing hair strand trap biomarkers, offering a long-term overview of alcohol and drug history. Hair samples collected near the scalp can reflect a detection period of up to 3 months for alcohol and drugs. Hair collection is straightforward, tough to tamper with, and simple to transport.

A 1.5-inch sample consisting of around 200 hair strands (comparable to the size of a #2 pencil) from the scalp provides 100mg, a perfect quantity for screening and validation. For EtG, add-ons, or tests beyond 10 panels, a specimen of 150mg is advised. Using a jeweler's scale for weighing the sample is recommended. If scalp hair is unavailable, a similar amount of body hair can be collected. "Head hair" specifically refers to scalp hair, while "body hair" includes all other types (facial, axillary, etc.).

Process Overview

There are four key steps in the laboratory processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial processing of a sample within a laboratory’s system, which includes ensuring the sample is sealed and shipped correctly, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any further data entry if needed beyond an electronic chain of custody system.

Screening entails a quick preliminary check for substances of abuse. Though cost-effective for ruling out drug use in most samples, screening positives require confirmation to be admissible in legal settings. Any samples with presumptive positive results in screening must undergo secondary confirmation.

For presumptively positive samples from the Screening stage, additional hair is extracted from the first specimen for the Extraction phase. This phase involves extracting drugs from hair at a lower concentration compared to other methods like urine or oral fluid; hence, hair drug screening is considered the most challenging methodology.

Confirmation of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation if necessary. The entire lab process from Accessioning through Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug usage for up to 90 days, unlike urine tests which offer a shorter detection window.
• Hard to deceive: Cheating a hair drug test is highly challenging, resulting in more precise outcomes.
• Delivers historical insights: They can show a pattern of drug consumption over time, beyond recent usage.

Limitations:

• Incapable of identifying recent consumption: Drugs usually become discernible in hair after about 5-7 days.
• Expense: Generally, hair drug tests are costlier compared to other drug test methods.
• Result variability: Factors such as hair color and personal differences in hair growth rate can influence drug metabolite levels in the hair.

Note: Although commonly described as "hair follicle tests", the examination actually analyzes the hair strand instead of the scalp's hair follicle
