Hair Follicle Drug Testing - Terre Haute, IN

What it is, How it works

Hair analysis is recognized as an effective means for identifying drug and alcohol consumption. The hair captures long-term evidence of substances by encapsulating biomarkers within the strands as they grow. If collected near the scalp, hair can indicate alcohol and drug use for up to three months. It is easy to collect, hard to tamper with, and simple to transport.

A sample of 1.5 inches with approximately 200 hair strands (similar to a #2 pencil) taken from the scalp provides 100mg, which is ideal for both screening and confirmation. For EtG tests, test add-ons, and tests exceeding 10 panels, 150mg of hair is advised. We suggest using a jeweler’s scale for weighing. If scalp hair is not available, equivalent body hair can be used. 'Head hair' specifically refers to scalp hair, while 'body hair' includes all other hair types (like facial or axillary hair).

Process Overview

The laboratory process for drug testing encompasses four crucial stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial logging of a sample within a laboratory's system. It involves confirming that the sample was properly sealed and shipped, generating a random LAN (Laboratory Accessioning Number), and accomplishing any supplementary data input when not provided by an electronic custody chain system.

Screening entails a preliminary assessment for drugs. Although Screening is cost-efficient for eliminating drug use in most samples, a positive result requires confirmation for legal admissibility. Samples with presumptively positive results in Screening mandate further confirmation.

Should a sample test presumptively positive in Screening, additional hair is extracted from the original sample for the Extraction phase. In Extraction, drug compounds are isolated from hair at significantly reduced concentrations compared to other methods (like urine or oral fluid), making hair drug tests complex to conduct.

Any positive screening determinants are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation if necessary. The full process, from Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair designation and aligns with ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can reveal drug use up to 90 days back, whereas urine tests have shorter detection spans.
• Hard to falsify: Hair drug testing is challenging to deceive, thus the results are more reliable.
• Offers historical insights: Provides data on drug use patterns over time, rather than just recent use.

Limitations:

• Inability to discern recent use: Drugs become identifiable in hair only after about 5-7 days.
• Expense: Hair drug testing usually costs more than other testing methods.
• Result variability: Attributes such as hair color and personal hair growth differences can influence drug metabolite concentrations in hair.

Note: Tests often called "hair follicle tests" actually analyze the hair strand, not the follicle beneath the scalp.
