Hair Follicle Drug Testing - Keachi, LA

What it is, How it works

Hair analysis has become regarded as an effective method for identifying substance and alcohol consumption. Hair acts as a long-term record of alcohol and drugs by embedding biomarkers within the strands of growing hair. When taken close to the head, hair may offer up to around a 3-month observation period for alcohol and drugs. Hair collection is straightforward, relatively challenging to tamper with, and convenient for shipping.

A section of hair measuring 1.5 inches with about 200 strands (similar in size to a #2 pencil) taken nearest the scalp will yield 100mg of hair, which is the optimal sample for testing and validation. For EtG, supplemental tests, and/or tests exceeding 10 panels, a 150mg sample is suggested. It's advisable to use a jeweler’s scale for weighing the sample. If head hair is unavailable, a comparable amount of body hair can be taken. Reference to head hair pertains solely to scalp hair. Body hair encompasses all other types of hair (such as facial, axillary, etc.).

Process Overview

The principal procedures included in the laboratory examination of a drug test outcome involve Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the preliminary handling of a sample into the laboratory’s system. This process entails confirming that the sample was correctly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry absent from an electronic chain of custody system.

Screening refers to an initial, rapid assessment for substance misuse. While Screening provides a cost-effective means to exclude drug usage in most samples, a positive screening needs confirmation for legal admissibility. Samples that are presumptively positive in Screening require secondary validation.

Should a sample be presumptively positive during Screening, additional hair is extracted from the initial sample and readied for Extraction. Here, drugs are extracted from hair at a notably lower concentration when compared to other methods (such as urine or oral fluid), underscoring hair drug screening as one of the most intricate methodologies to execute.

Validation of any positive screening outcome is carried out via GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are cleansed before confirmation if required. The entire laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use over up to 90 days, compared to shorter timeframes with urine tests.
• Challenge in falsification: It is exceedingly hard to falsify a hair drug test, enhancing result accuracy.
• Provision of historical insight: It can outline a pattern of substance use across a time span, not just recent activity.

Limitations:

• Inability to identify recent use: It might take about 5-7 days for drugs to be detectable in hair.
• Expense: Hair drug tests tend to be pricier than other drug testing techniques.
• Variability in findings: Factors like hair color and personal variations in hair growth might influence the concentration of drug metabolites in the hair.

Note: Even though termed as "hair follicle tests", the evaluation is conducted on the hair strand, not the follicle under the scalp.

Why Hair Follicle Testing Beats Urine Testing

In the context of Keachi, LA, hair follicle testing offers an edge over traditional urine tests in several facets. Accuracy is paramount, and hair samples provide a more reliable insight into long-term substance use.
