Hair Follicle Drug Testing - Yorktown, IN

What it is, How it works

The use of hair analysis has become an effective means for identifying drug and alcohol consumption. Hair offers a lengthy timeline for monitoring alcohol and drugs by embedding biomarkers within the strands during hair growth. When harvested near the scalp, hair can provide a detection window of up to around three months for alcohol and drugs. Collecting hair is straightforward, relatively challenging to tamper with, and convenient to transport.

A sample measuring 1.5 inches, consisting of roughly 200 hair strands (approximately the diameter of a #2 pencil) nearest to the scalp, will yield 100mg of hair, which is the optimal amount for analysis and validation. For EtG, add-ons, and tests exceeding 10 panels, 150mg of the sample is advised. It is suggested to measure the sample using a jeweler’s scale. If scalp hair is not available, a comparable quantity of body hair can be used. When mentioning head hair, we specifically mean scalp hair. Body hair denotes any other types (such as facial, axillary, etc.).

Process Overview

The principal stages in processing a drug test result in a laboratory are Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initial entry of a sample into the laboratory’s database. This step confirms the sample was sealed and transported correctly, assigns a unique LAN (Laboratory Accessioning Number), and completes any necessary data entry not covered by an electronic chain of custody system.

Screening is an initial rapid assessment for drugs of abuse. While Screening is an economical approach to exclude drug presence in most samples, a positive screening result requires confirmation to be valid in legal proceedings. Any samples presumed positive in Screening must undergo secondary confirmation.

If a Screening results in a presumptive positive, additional hair from the initial sample is prepared for Extraction. In this phase, drugs are isolated from hair at a much lower concentration compared to other methods (e.g., urine or oral fluids), underscoring the complexity of hair drug screening.

Confirmation of any presumptive positive screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The complete laboratory procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, compared to urine tests which have a shorter detection timeframe.
• Challenge to manipulate: Hair drug tests are tough to tamper with, enhancing result accuracy.
• Tracks drug consumption history: It reveals a pattern of drug use over time, rather than just recent usage.

Limitations:

• No detection of recent use: It takes roughly 5-7 days for drugs to be detectable in hair.
• Expense: Hair drug tests typically cost more than other drug testing methods.
• Result variability: Factors like hair color and individual differences in hair growth can impact the concentration of drug metabolites in the hair.

Note: Although commonly called "hair follicle tests", the analysis concerns the hair strand and not the follicle beneath the scalp.
