Hair Follicle Drug Testing - Felton, DE

What it is, How it works

Hair testing has gained recognition as an effective method for identifying drug and alcohol consumption. Hair captures long-term evidence of alcohol and drug use through the encapsulation of biomarker traces within its growing strands. When taken from the scalp area, hair samples can offer a detection timeframe of up to three months for substances like alcohol and drugs. The collection process is straightforward, challenging to tamper with, and uncomplicated to transport.

A sample comprising 1.5 inches of hair (roughly 200 strands, akin to the diameter of a #2 pencil) near the scalp yields 100mg of hair, which is the optimal quantity for both preliminary and confirmatory testing. For tests detecting EtG, additional screens, or panels exceeding 10, it is advisable to gather 150mg of the sample. It is recommended to use a jeweler’s scale for weighing. If scalp hair isn't available, a comparable quantity of body hair may be taken. Note that 'head hair' specifically refers to scalp hair, while 'body hair' denotes all other types (including facial, axillary, etc.).

Process Overview

The laboratory procedure for processing drug test results encompasses four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first step where a sample is integrated into a laboratory’s system. It involves checking that the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any data input not covered by an electronic chain of custody system.

Screening consists of a preliminary assessment for drug presence. While Screening effectively eliminates a large number of samples from showing drug use, any positive findings must be verified for legal validity. Samples with presumptive positive results in Screening necessitate additional confirmation.

Should a sample yield a presumptive positive during Screening, additional hair from the original sample is prepared for Extraction. During this phase, drugs are extracted from hair at more diminutive concentrations compared to other methodologies (such as urine or oral fluid), which underscores the complexity of hair drug screening.

Confirmation of any positive Screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo washing before Confirmation as required. The thorough laboratory process from Accessioning to Confirmation is inspected under the CAP (College of American Pathologists) Hair criteria and compliant with ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can identify drug use over a period of up to 90 days, unlike urine tests that offer a shorter detection duration.
• Hard to falsify: Tampering with hair drug tests is notably challenging, thus ensuring greater result accuracy.
• Supplies historical insight: It reveals a timeline of drug usage, beyond just recent activity.

Limitations:

• Inability to detect recent usage: Drugs typically take 5-7 days to become traceable in hair.
• Expense: Hair-based drug tests tend to be pricier than other testing options.
• Result variability: Factors like hair color and individual hair growth rates can influence drug metabolite levels in the hair.

Note: The term "hair follicle tests" is often used, but the analysis actually examines the hair strand, rather than the follicle beneath the scalp.
