Hair Follicle Drug Testing - Robins, IA

What it is, How it works

Hair analysis has gained recognition as an effective method for identifying drug and alcohol consumption. By depositing biomarkers in the fibers of the developing hair strand, hair records an extended history of substance use. When gathered near the scalp, hair can offer a detection range for alcohol and drugs up to around 3 months. Hair collection is straightforward, relatively tamper-proof, and easily shippable.

A 1.5-inch hair sample consisting of about 200 strands (approximately the width of a #2 pencil) closest to the scalp yields 100mg of hair, the optimal sample size for testing and verification. For EtG, additional tests, and/or tests exceeding 10 panels, a specimen of 150mg is advised. It is recommended to measure the specimen with a jeweler's scale. Should scalp hair be unavailable, a corresponding amount of body hair can be used. When mentioning head hair, we refer specifically to scalp hair. Body hair includes all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result involves four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial entry of a sample into a lab’s system. This step involves confirming that the sample was properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing supplementary data entry absent in an electronic chain of custody system.

Screening conducts an initial rapid assessment for drug presence. Although Screening is an economical method to eliminate drug presence in most samples, a positive screen must be validated to be legally defensible. Samples that are presumptively positive during Screening need further validation.

If Screening indicates a presumptive positive, additional hair is retrieved from the original sample for Extraction. During this phase, drugs are extracted from hair at significantly lower levels than in alternative methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.

Positive screening confirmations are executed using GC/MS, GC/MS/MS, or LC/MS/MS methodologies. All samples with presumptive positives are washed prior to confirmation if required. The comprehensive lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair directive and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection range: Hair drug tests can detect substances up to 90 days, unlike urine tests with shorter detection periods.
• Hard to manipulate: Hair drug tests are challenging to falsify, enhancing result reliability.
• Offers historical insight: It charts drug use trends over time, beyond immediate consumption.

Limitations:

• Inability to spot recent use: Drugs appear in hair approximately 5-7 days post-use.
• Expense: Hair drug tests tend to cost more compared to other methods.
• Result variability: Factors like hair color and personal growth differences can influence drug metabolite levels.

Note: The term "hair follicle tests" is misleading, as the test examines the hair strand rather than the scalp-situated follicle.
