Hair Follicle Drug Testing - Norwalk, IA

What it is, How it works

Hair testing is widely recognized as an effective method for identifying drug and alcohol use. Hair offers a comprehensive record of alcohol and drug consumption by capturing biomarkers within the hair's fibers during its growth. When collected near the scalp, hair can reveal drug and alcohol use for up to three months. Hair collection is straightforward, challenging to tamper with, and simple to transport.

A 1.5-inch hair sample consisting of approximately 200 strands (about the diameter of a #2 pencil) taken closest to the scalp yields 100mg, the optimal amount for both screening and confirmation. For EtG tests, additional tests, or those exceeding 10 panels, a 150mg sample is suggested. It is recommended to weigh the sample using a jeweler’s scale. If scalp hair isn't available, an equivalent quantity of body hair can be used. Reference to head hair exclusively pertains to scalp hair. Body hair encompasses other types (facial, axillary, etc.).

Process Overview

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

Accessioning refers to the initial handling of a sample within the laboratory system. This step involves confirming that the sample was correctly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from the electronic chain of custody.

Screening serves as a preliminary assessment for drug abuse. Although Screening is cost-efficient for negating drug use in most samples, positive results require verification for legal admissibility. Samples that test presumptive positive in Screening necessitate a secondary confirmation.

For presumptive positive results in Screening, additional hair is taken from the original sample for Extraction. In this phase, drugs are extracted at much lower concentrations compared to other methods (e.g., urine or oral fluid), rendering hair drug screening the most complex method to execute.

Confirmation of positive screening outcomes is performed via GC/MS, GC/MS/MS, or LC/MS/MS. Necessary washing of all presumptive positive samples occurs prior to confirmation. The entire laboratory process, from Accessioning to Confirmation, is assessed under CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests that have a shorter detection period.
• Hard to manipulate: Cheating on a hair drug test is extremely difficult, enhancing result accuracy.
• Offers historical insight: It reveals a usage pattern over time, not just recent drug use.

Limitations:

• Inability to detect recent use: It takes about 5-7 days for drugs to appear in hair.
• Expense: Typically, hair drug tests are costlier than other testing methods.
• Result variability: Factors like hair color and individual hair growth differences can influence drug metabolite concentration in hair.

Note: Despite commonly being termed "hair follicle tests", the analysis focuses on the hair strand, not the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

Why does hair follicle testing present a superior alternative to urine testing in Norwalk, IA? The key is in its enhanced detection accuracy and comprehensive reliability. Hair testing captures a broader drug use history, offering insights urine tests cannot.
