Hair Follicle Drug Testing - Randlett, OK

What it is, How it works

Hair analysis has emerged as an effective mechanism for identifying drug and alcohol consumption. Hair strands capture biomarkers, offering a long-term record of alcohol and drug intake. When cut close to the scalp, hair samples can reveal a detection window of up to three months for various substances. Hair is straightforward to gather, challenging to tamper with, and simple to mail.

By collecting a 1.5-inch section of about 200 hair strands (roughly equivalent to a #2 pencil's width) nearest to the scalp, you obtain 100mg of hair, which is an optimal quantity for testing and confirmation. For EtG and extended or panel tests beyond ten, 150mg of the hair sample is suggested. It's advisable to use a jeweler’s scale to measure the sample. If scalp hair is not an option, an equivalent quantity of body hair can be utilized. References to head hair pertain solely to scalp hair, whereas body hair encompasses all other hair categories (facial, axillary, etc.).

Process Overview

The key stages in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning represents the initial phase of inputting a sample into a laboratory’s system. This step involves confirming that the sample was appropriately sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary additional data entries that aren't covered by an electronic chain of custody system.

Screening offers an initial rapid assessment for substances of abuse. Although Screening is an economical approach for excluding drug use in most samples, any positive screen requires confirmation for court admissibility. Samples testing presumptively positive during Screening necessitate a follow-up confirmation.

Should a sample test presumptively positive during the Screening phase, more hair is retrieved from the initial specimen for the Extraction process. Here, drug compounds are extracted from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the most complex methodology available.

Positive Screening results are verified via GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples receive a necessary wash. The comprehensive lab procedure from Accessioning through to Confirmation is scrutinized following the CAP (College of American Pathologists) Hair protocols and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests can identify drug usage for as long as 90 days, surpassing the shorter timeframe of urine tests.
• Reduced likelihood of manipulation: Hair drug tests are difficult to alter, enhancing result accuracy.
• Displays usage history: Offers an extended view of drug usage patterns over time, beyond recent usage.

Limitations:

• Unable to detect recent intake: Drugs require approximately 5-7 days before becoming traceable in hair.
• Expense: Hair drug tests generally incur higher costs than other drug testing methods.
• Result variability: Factors like hair color and individual hair growth variations can impact drug metabolite concentrations in the hair.

Note: Although often termed “hair follicle tests,” the analysis targets the hair strand rather than the hair follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing
