Hair Follicle Drug Testing - Greenville, MS

What it is, How it works

Hair testing has gained recognition as a robust tool for identifying drug and alcohol usage. Hair encapsulates a long-term record of alcohol and other drugs by embedding biomarkers in the fibers of the hair strand as it grows. When collected from near the scalp, hair can provide approximately a 3-month detection window for alcohol and other drugs. Hair collection is straightforward, moderately challenging to tamper with, and easy to send.

A 1.5-inch sample containing about 200 hairs (around the thickness of a #2 pencil) taken closest to the scalp will yield 100mg of hair, the optimal sample size for both screening and confirmation. For EtG, additional testing, and tests exceeding 10 panels, 150mg of hair is advised. We recommend using a jeweler’s scale for weighing the sample. If scalp hair is not available, the same quantity of body hair may be used instead. The term head hair refers exclusively to scalp hair, whereas body hair encompasses all other kinds (facial, axillary, etc.).

Process Overview

The laboratory process for generating a drug test result consists of four major steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the beginning of sample entry into a laboratory’s workflow. This involves verifying that the sample was properly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data entry not covered by an electronic chain of custody system.

Screening entails an initial rapid examination for drugs of abuse. Although Screening is an economical way to dismiss drug usage in the majority of samples, a positive screen needs verification to be legally admissible. Any samples that test presumptively positive during Screening require a secondary confirmation.

If a sample shows a presumptive positive in the Screening phase, more hair is extracted from the original specimen and readied for Extraction. In this period, drugs are extracted from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), which makes hair drug screening the most challenging method to carry out.

Confirmation of any positive screening result is achieved using GC/MS, GC/MS/MS or LC/MS/MS. All samples with presumptive positives are washed before confirmation as required. The entire laboratory sequence from Accessioning to Confirmation is scrutinized under both College of American Pathologists (CAP) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can detect drug use for up to 90 days, as opposed to urine tests, which have shorter detection durations.
• Hard to deceive: Cheating on a hair drug test is extremely difficult, enhancing the accuracy of the results.
• Offers historical perspective: It can reveal a pattern of drug use over time, not just recent activity.

Limitations:

• Cannot detect recent use: Drugs become detectable in hair approximately 5-7 days post-use.
• Expense: Hair drug tests generally cost more than other drug testing methods.
• Result variability: Elements like hair color and individual hair growth variations can influence the concentration of drug metabolites in the hair.

Note: Despite being called "hair follicle tests", the analysis is conducted on the hair strand, not the follicle beneath the scalp.
