Hair Follicle Drug Testing - Petersburg, NE

What it is, How it works

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol use. Hair offers an extended timeline of substance presence by capturing biomarkers within the fibers of the developing hair strand. When taken near the scalp, hair gives a detection period for up to around 90 days for alcohol and other drugs. Collection is straightforward, challenging to tamper with, and convenient to transport.

A sample of 1.5 inches consisting of approximately 200 hair strands (comparable to a #2 pencil thickness) closest to the scalp yields 100mg of hair, the optimal quantity for assessment and validation. For EtG, additional tests, and/or those beyond 10 panels, a 150mg specimen is advised. It's recommended to use a jeweler’s scale to weigh the sample. If scalp hair is not available, a comparable amount of body hair can be utilized. References to head hair strictly mean scalp hair, whereas body hair includes all other hair types (facial, axillary, etc.).

Process Overview

The primary processes in laboratory analysis of drug test results consist of Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step of processing a sample within a laboratory’s system, which comprises verifying the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any further data entry absent from an electronic chain of custody system.

Screening entails a preliminary quick evaluation for drugs. Although Screening is an economical method to eliminate drug use in most samples, a positive result must be authenticated for legal admissibility. Samples with presumptive positive results need further confirmation.

In cases where a sample is presumptively positive during Screening, additional hair is extracted from the initial sample for the Extraction stage. This step extracts drugs from hair at a notably lower concentration compared to other methods (e.g., urine or oral fluid), thereby making hair drug screening one of the more challenging techniques to execute.

Positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing before confirmation is carried out as needed. The comprehensive laboratory procedure from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and aligns with ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use up to 90 days, whereas urine tests have a shorter detection timeframe.
• Hard to deceive: Cheating a hair drug test is quite difficult, enhancing the accuracy of outcomes.
• Historical usage pattern: It yields a usage trend across time and not merely recent consumption.

Limitations:

• No recent usage detection: It takes about 5-7 days for substances to show in hair.
• Expense: Hair drug tests are typically more costly than other methods.
• Result variability: Aspects like hair color and individual differences in hair growth may influence the concentration of drug metabolites in hair.

Note: Despite being called "hair follicle tests", the analysis actually targets the hair strand, not the follicle beneath the scalp.
