Hair Follicle Drug Testing - Terrell, TX

What it is, How it works

Hair drug testing is now recognized as an effective method for identifying substance and alcohol usage. Hair captures a detailed record of alcohol and drug intake by embedding markers within the hair strands as they grow. When obtained near the scalp, hair offers a detection timeframe of up to around three months for both alcohol and other drugs. The collection process is straightforward, the sample is tough to tamper with, and it is convenient to transport.

A 1.5-inch portion consisting of roughly 200 hair strands (similar in size to a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the preferred amount for both screening and validation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg is advised. Measuring the sample weight on a jeweler’s scale is suggested. In cases where scalp hair cannot be used, a similar quantity and weight of body hair should be collected. When we mention head hair, it signifies scalp hair only. Body hair encompasses all other varieties (such as facial or body hair).

Process Overview

The laboratory analysis of a drug test result comprises four essential phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a specimen into a lab’s database. This encompasses ensuring the specimen was correctly sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and filling in any missing data not included through an electronic chain of custody framework.

Screening represents a preliminary examination for abused substances. Although screening provides an economical approach to eliminating drug use for most samples, a positive result needs verification for legal acceptability. All samples that exhibit presumptive positives during screening require further confirmation.

If a sample shows a presumptive positive during the Screening phase, more hair is extracted from the primary sample for the Extraction phase. Drugs are then extracted from hair at lower levels compared to other techniques (e.g., urine or oral fluid), which positions hair drug screening as the most challenging methodology to execute.

To verify any positive screening results, techniques such as GC/MS, GC/MS/MS, or LC/MS/MS are utilized. All samples showing presumptive positivity undergo washing before confirmation if necessary. Each laboratory stage from Accessioning through Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair category and accreditation to ISO / IEC 17025 criteria.

Advantages of hair drug testing:

• Extended detection window: Hair drug assessments can identify drug usage for up to 90 days, contrasting with the shorter timeframe of urine tests.
• Hard to manipulate: Altering the results of a hair drug test is notably difficult, increasing result reliability.
• Gives usage history: It offers a timeline of drug intake, unlike tests that only show recent consumption.

Limitations:

• Inability to identify recent intake: Drugs typically need 5-7 days to become noticeable in hair.
• Expense: Hair drug tests tend to be pricier compared to alternative drug testing methods.
• Result variability: Individual differences like hair color and growth rate can influence drug metabolite concentration in hair.

Note: Although commonly termed as "hair follicle tests", the assessment actually examines the hair strand, not the scalp-based hair follicle.
