Hair Follicle Drug Testing - Biscay, MN

What it is, How it works

Using hair testing has emerged as an effective method for identifying drug and alcohol consumption. Hair offers a prolonged history of substance use by locking biomarkers within the strands of growing hair. When collected near the scalp, hair can reveal up to roughly a 3-month detection period for alcohol and drugs. Collecting hair is straightforward, challenging to tamper with, and simple to transport.

A sample of length 1.5 inches, consisting of about 200 hair strands (approximately the size of a #2 pencil) nearest the scalp, yields 100mg of hair—the optimal amount for both screening and confirmation. For EtG add-ons, and/or tests exceeding 10 panels, it’s advised to collect 150mg of the specimen. We suggest using a jeweler’s scale for specimen weighing. If scalp hair cannot be obtained, a similar quantity of body hair can be used. References to head hair specifically pertain to scalp hair, while body hair includes all other types (facial, axillary, etc.).

Process Overview

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

Accessioning involves the entry of a sample into a laboratory system. This step ensures proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any data entry tasks not addressed by an electronic chain of custody system.

Screening performs an initial, rapid evaluation for drug abuse. Although Screening is an economical method to negate drug use in most samples, a positive result requires confirmation for legal admissibility. All samples positive in Screening must undergo secondary confirmation.

If a sample is positive in the Screening phase, additional hair is taken from the original sample for Extraction. Here, drugs are separated at a notably lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug testing among the hardest methodologies.

To confirm any positive result from screening, GC/MS, GC/MS/MS, or LC/MS/MS is used. All samples that test positive initially undergo necessary washing before confirmation. The whole process from Accessioning to Confirmation is overseen under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Prolonged detection period: Hair drug tests can identify drug usage for up to 90 days, whereas urine tests offer a shorter detection timeframe.
• Hard to deceive: It’s extremely challenging to falsify a hair drug test, thereby enhancing result accuracy.
• Supply past data: It can show a trend of drug use over a stretch of time, rather than just recent usage.

Limitations:

• Inability to identify recent use: Drugs become detectable in hair approximately 5-7 days post-use.
• Expense: Hair drug tests tend to be pricier than alternative drug testing methods.
• Result variations: Elements like hair color and personal hair growth variations can influence drug metabolite concentrations in hair.

Note: Although often termed "hair follicle tests," the analysis actually involves the hair strand, not the follicle below the scalp.
