Hair Follicle Drug Testing - Greenock, PA

What it is, How it works

Hair testing is now recognized as an effective method for identifying drug and alcohol consumption. This approach offers a long-term record of substance use by capturing biomarkers within the strands during hair growth. If taken near the scalp, it provides roughly a 90-day detection period for alcohol and drugs. Hair samples are easy to obtain, less prone to tampering, and convenient to transport.

A 1.5-inch section containing approximately 200 hairs, equivalent to a #2 pencil's thickness, near the scalp offers 100mg of hair, which is ideal for screening and confirmation. For EtG add-ons or tests exceeding 10 panels, 150mg is suggested. It's advisable to measure the sample using a jeweler’s scale. If scalp hair isn't available, a similar quantity of body hair can be gathered. Head hair refers specifically to scalp hair, whereas body hair encompasses all other types (facial, axillary, etc.).

Process Overview

Laboratory processing of drug tests involves four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial handling of a sample within the laboratory system, ensuring the sample is sealed, properly delivered, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data entry that isn’t automatically provided by an electronic chain of custody.

Screening provides an initial quick evaluation for drugs of abuse. While Screening is affordable and effective for eliminating drug usage in most samples, a positive result requires confirmation for legal admissibility. Samples with presumptive positives in Screening need further confirmation.

When a sample tests presumptive positive during Screening, more hair is gathered from the initial sample for Extraction. Here, drugs are removed from hair at far lower concentrations than in other methods (e.g., urine or oral fluid), contributing to the complexity of hair drug screening.

Confirmation of any positive result from Screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Before confirmation, all presumptive positive samples are washed as needed. The entire lab process from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and the accreditation standards of ISO / IEC 17025.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, whereas urine tests have a more limited detection span.
• Hard to falsify: Cheating a hair drug test is notably challenging, leading to more reliable results.
• Tracks historical use: Provides insights into drug use patterns over time, rather than just recent activity.

Limitations:

• Incapable of detecting recent use: Drugs become detectable in hair after about 5-7 days.
• Expense: Hair drug testing typically incurs higher costs compared to other methods.
• Result variability: Factors like hair color and personal differences in hair growth can influence the levels of drug metabolites in hair.

Note: Although commonly termed "hair follicle tests", the actual analysis is conducted on the strand of hair, not the follicle beneath the scalp.
