Hair Follicle Drug Testing - Gravity, IA

What it is, How it works

Hair analysis is now recognized as a robust means for identifying the consumption of drugs and alcohol. The hair encapsulates a long-term record of substance use by embedding biomarkers within the hair fiber as it grows. When trimmed close to the head, it can provide an approximate 3-month detection period for alcohol and drugs. The process of collecting hair is straightforward, hard to tamper with and facilitates easy shipment.

A hair sample measuring 1.5 inches comprising approximately 200 strands (comparable to the circumference of a #2 pencil) near the scalp will yield 100mg of hair—the optimal amount for testing and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, a sample of 150mg is suggested. Using a jeweler’s scale for precise weighing is advised. If head hair is not available, an equivalent portion of body hair can be used. The term head hair denotes scalp hair exclusively, whereas body hair encompasses all other hair varieties (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result involves four fundamental steps: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample undergoes initial processing into the lab’s framework. This process verifies the sample’s seal and proper shipment, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any additional data entry absent from an electronic chain of custody system.

Screening includes a preliminary swift evaluation for drug presence. Although it serves as a budget-friendly tactic to eliminate drug use on the majority of samples, a confirmed screen is necessary for court admissibility. Any samples detected as likely positive during Screening demand a secondary confirmation.

If Screening suggests a sample might be positive, further hair is extracted from the original specimen and moved to Extraction. Within this phase, drugs are extracted from hair at a notably lower concentration than other methods (like urine or oral fluid), which makes hair drug screening one of the most challenging techniques to perform.

Confirmation of any detected positive screen employs GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptive positive result is cleansed prior to confirmation if necessary. This entire laboratory sequence, from Accessioning to Confirmation, is assessed under both the CAP (College of American Pathologists) Hair designation and with accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection span: Hair drug tests can identify drug use up to 90 days, while urine tests cover a shorter window.
• Cheating difficulty: Hair drug tests are notably tough to bypass, rendering more precise results.
• Provision of historical insights: It shows a timeline of drug use over a duration, not just recent activity.

Limitations:

• Incapability to detect recent intake: Detection in hair requires roughly 5-7 days post-drug use.
• Expense: Hair drug tests generally incur higher costs compared to other testing techniques.
• Result variability: Factors such as hair pigmentation and individual growth rates can influence the concentration of drug residues in hair.

Note: While commonly named "hair follicle tests", the analysis evaluates the hair strands, not the follicles beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing
