Hair Follicle Drug Testing - Summerland, CA

What it is, How it works

Hair testing is increasingly viewed as a potent solution for identifying drug and alcohol consumption. Hair captures a long-term record of these substances by embedding biomarkers in the fibers of the growing strand. When obtained near the scalp, hair can offer nearly a 3-month window for detecting alcohol and other drugs. It is easy to collect, challenging to tamper with, and convenient to transport.

A 1.5-inch segment of about 200 hair strands, roughly the size of a #2 pencil, closest to the scalp yields 100mg of hair, which is the optimal quantity for testing and confirmation. For EtG, additional tests, and/or panels exceeding ten, a sample weighing 150mg is suggested. It's best to measure the sample on a jeweler's scale. If scalp hair is unavailable, an identical quantity of body hair can be used. When we mention head hair, we specifically mean scalp hair. Body hair encompasses all other hair types (e.g., facial, axillary).

Process Overview

There are four primary stages in the laboratory analysis of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into a laboratory's system. This step ensures the sample was properly sealed and sent, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry not included in an electronic chain of custody system.

Screening consists of a preliminary rapid check for drugs of abuse. While Screening offers a cost-effective means to exclude drug use in most samples, a confirmed positive screen is necessary for court admission. Any samples that are suggestively positive in Screening require a follow-up confirmation.

If a sample tests suggestively positive during Screening, additional hair is extracted from the original sample for Extraction. In this step, drugs are removed from hair at a significantly lower concentration compared to other methods (such as urine or oral fluid), which is why hair drug screening is the most complex methodology to execute.

Confirmation of any positive screening results is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing presumptive positivity undergo washing prior to confirmation if needed. The full laboratory process, from Accessioning to Confirmation, is examined according to the CAP (College of American Pathologists) Hair designation and is accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace drug usage for up to 90 days, while urine tests offer a shorter detection timeframe.
• High difficulty to falsify: It is exceedingly tough to deceive a hair drug test, enhancing result accuracy.
• Offers historical insights: It can trace a timeline of drug use over an extended period, not limited to recent usage.

Limitations:

• Incapable of detecting recent usage: Drugs become detectable in hair only after about 5-7 days.
• Higher cost: Hair drug tests typically cost more than other drug testing techniques.
• Result variability: Factors like hair color and individual differences in hair growth can influence the concentration of drug metabolites in hair.

Note: Although commonly called "hair follicle tests", the test analyzes the hair strand and not the follicle beneath the scalp.
