Hair Follicle Drug Testing - Buell, MO

What it is, How it works

The use of hair testing has evolved into an effective method for identifying drug and alcohol consumption. The fibers of a growing hair strand capture biomarkers, providing a prolonged history of substance use. When collected near the scalp, the detection period for substances can extend up to three months. The collection process is straightforward; it is difficult to tamper with and simple to transport.

Collecting a 1.5-inch piece of around 200 hair strands, comparable to the thickness of a #2 pencil, yields 100mg—the prime sample size for both screening and confirmation tests. For EtG, supplementary tests, or tests exceeding 10 panels, 150mg of hair is advisable. We suggest using a jeweler’s scale for accuracy in measuring the sample. If scalp hair is unavailable, an equivalent amount of body hair can be collected. When we mention head hair, it specifically pertains to scalp hair, while body hair includes other hair types (e.g., facial, axillary).

Process Overview

Four key steps are involved in processing a drug test in the lab: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase where a sample is processed into a lab's system, ensuring it was sealed and shipped correctly. A random LAN (Laboratory Accessioning Number) is assigned, and any required data entry not covered by an electronic chain of custody is completed.

Screening is a preliminary check for drug abuse. Although screening is cost-effective for eliminating drug use for most samples, any positive findings must be confirmed to be court-admissible. Samples testing positive during Screening require further confirmation.

For samples testing presumptively positive during Screening, additional hair is prepared for Extraction, where drugs are removed from hair at a much lower concentration than other methods (like urine or oral fluid), making hair drug screening notably challenging.

GC/MS, GC/MS/MS, or LC/MS/MS methods are employed for confirming any positive screening results. All samples with presumptive positives undergo washing before confirmation, ensuring comprehensive review by the CAP (College of American Pathologists) Hair designation and accreditation to ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can identify drug use spanning up to 90 days, offering a longer window than urine tests.
• Ensures accuracy: Cheating on hair drug tests is highly challenging, ensuring more precise results.
• Tracks usage history: It reflects a pattern of drug use, not merely recent intake.

Limitations:

• Limited recent detection: Drugs become detectable in hair approximately 5-7 days post-use.
• Higher cost: Hair drug tests typically incur higher expenses than other testing methods.
• Result variability: Factors like hair color and individual differences in hair growth may impact drug metabolite concentrations in hair.

Note: Although often referred to as "hair follicle tests," this test analyzes the hair strand, not the follicle beneath the scalp.
