Hair Follicle Drug Testing - Corpus Christi, TX

What it is, How it works

Hair testing has developed into a highly regarded method for identifying drug and alcohol consumption. By embedding biomarkers within the fibers of the developing hair strand, hair offers an extended history of alcohol and drug use. When gathered near the scalp, hair can provide an estimated 90-day timeframe for detecting alcohol and other substances. Hair is straightforward to collect, challenging to tamper with, and simple to transport.

A 1.5-inch portion containing approximately 200 strands of hair (about the dimension of a #2 pencil) nearest to the scalp yields 100mg of hair, the preferred amount for testing and validation. For EtG, additional panels, or tests exceeding 10 panels, a quantity of 150mg of hair is advisable. It's suggested to measure the sample using a jeweler’s scale. If scalp hair is unobtainable, an equivalent segment of body hair may be used. When discussing head hair, we specifically mean scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The process of analyzing a drug test result in the laboratory consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initial handling of a sample into a laboratory’s system. This process involves ensuring the sample was correctly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and performing supplementary data entry not covered by an electronic chain of custody system.

Screening entails an initial brief assessment for drugs of abuse. Screening serves as a cost-effective method to exclude drug usage in most samples, though a positive screen must undergo confirmation for courtroom admissibility. Any samples that are initially positive in Screening necessitate a subsequent confirmation.

If the Screening stage indicates a presumptive positive result, further hair is extracted from the initial sample and prepared for Extraction. This phase involves retrieving drugs from hair at a significantly lower concentration than other methodologies (e.g., urine or oral fluid), which is why hair drug screening is among the most challenging methodologies to execute.

Confirmation of any positive screen results is performed through GC/MS, GC/MS/MS, or LC/MS/MS. Samples with presumptive positive results are cleansed before confirmation as required. The comprehensive laboratory procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the accreditation according to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can ascertain drug usage for up to 90 days, whereas urine tests possess a briefer detection period.
• Resistance to deception: It is exceedingly challenging to evade a hair drug test, enhancing the precision of results.
• Supplies historical insights: It can showcase a sequence of drug use over time, not merely recent consumption.

Limitations:

• Incapable of spotting recent usage: It requires roughly 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug tests typically incur higher costs compared to alternative drug testing methods.
• Result variability: Elements such as hair coloration and personal differences in hair growth can influence the concentration of drug metabolites in hair.

Note: Despite the term "hair follicle tests" often being used, the test itself examines the hair strand and not the hair follicle within the scalp.
