Hair Follicle Drug Testing - St. Michael, AK

What it is, How it works

Hair analysis has emerged as an effective means for identifying drug and alcohol consumption. The hair encases biomarkers in the strands as it grows, offering extended information on alcohol and drug history. When sourced near the scalp, hair can reveal substance usage over an approximate three-month span. Hair collection is straightforward, challenging to tamper with, and simple to send.

A sample of 1.5 inches with roughly 200 hair strands (comparable to a #2 pencil's thickness) taken from near the scalp will yield 100mg, which is the perfect sample size for both screening and validation. For EtG, additional tests, and tests above 10 panels, a sample of 150mg is suggested. The use of a jeweler's scale is advised for specimen weighing. In cases where scalp hair isn't available, a comparable sample of body hair will suffice. Here, head hair pertains solely to the scalp, whereas body hair includes all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of drug tests involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial intake of a sample into the laboratory's framework, ensuring proper sealing and shipment of the sample, designating a random LAN (Laboratory Accessioning Number), and completing any additional required data entry absent from an electronic chain of custody.

Screening offers a preliminary and swift evaluation for substance abuse. Although Screening is an economical method for dismissing drug usage in the majority of cases, positive screens must be confirmed for legal admissibility. Those samples identified as presumptive positives in Screening need a secondary confirmation.

When a sample shows a presumptive positive in Screening, additional hair is retrieved from the original sample for Extraction. Here, substances are extracted from the hair at significantly lower concentrations than alternative methods (like urine or oral fluid), which is why hair drug analysis is notably challenging.

GC/MS, GC/MS/MS, or LC/MS/MS is employed for the Confirmation of any positive screening. Presumptive positive samples undergo washing before confirmation when necessary. The entire process, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can unveil drug usage over 90 days, in contrast to the shorter timeframe detected by urine tests.
• Cheating is challenging: Manipulating a hair drug test is exceedingly difficult, thus enhancing the accuracy of results.
• Chronological data provision: It delivers usage patterns over time and not solely recent consumption.

Limitations:

• Inability to detect recent use: Drugs require about 5-7 days to appear in hair for detection.
• Higher cost: Hair drug tests typically cost more than other testing methods.
• Result variability: Factors such as hair color and personal differences in hair growth impact drug metabolite levels in hair.

Note: Often misnamed "hair follicle tests", the procedure actually examines the hair strand and not the follicle under the scalp.

Why Hair Follicle Testing Beats Urine Testing
