Hair Follicle Drug Testing - Grosse Pointe Woods, MI

What it is, How it works

Hair testing is increasingly regarded as an effective method for detecting drug and alcohol use. Hair captures a long-term record of substance use by embedding biomarkers within the growing hair strand. When sampled close to the scalp, hair can reveal a detection history of up to roughly 3 months for alcohol and drugs. Hair samples are easy to collect, challenging to tamper with, and simple to transport.

A 1.5-inch segment consisting of approximately 200 strands of hair (comparable to a #2 pencil's thickness) nearest the scalp yields 100mg of hair, making it an optimum sample for screening and confirmation tests. For EtG, supplemental, and tests exceeding 10 panels, 150mg is advised. It is ideal to measure the sample with a jeweler's scale. If scalp hair cannot be collected, a similar amount of body hair can be utilized. "Head hair" refers specifically to scalp hair only. "Body hair" includes all other types, such as facial or axillary.

Process Overview

The primary stages in lab processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial processing of a sample in a laboratory setting. This step ensures the sample was properly sealed and sent, assigns it a unique LAN (Laboratory Accessioning Number), and completes any additional required data entry absent in an electronic chain of custody system.

Screening consists of a preliminary check for substances of abuse. Although Screening is a cost-efficient approach to exclude drug use for most samples, a positive outcome needs confirmation for court acceptability. Any samples testing presumptively positive during Screening necessitate secondary confirmation.

Should a sample show presumptive positivity during Screening, additional hair from the original sample is used for Extraction. This phase involves extracting drugs from hair in concentrations significantly lower than methods like urine or oral fluids, contributing to the complexities of hair drug screening.

To verify any positive screen results, Confirmation is conducted through techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results undergo a wash before Confirmation, if necessary. The entire laboratory procedure, from Accessioning to Confirmation, is audited under both the CAP (College of American Pathologists) Hair standards and ISO/IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for up to 90 days, whereas urine tests have a more limited detection range.
• Hard to deceive: Successfully cheating a hair drug test is highly challenging, thus enhancing result reliability.
• Shows usage history: It outlines a trend of substance use over a duration, not just recent consumption.

Limitations:

• Inability to detect recent use: Drugs become traceable in hair only after about 5-7 days.
• Expense: Hair drug tests often cost more than other drug screening options.
• Result variations: Factors like hair color and individual hair growth differences can influence drug metabolite presence in hair.

Note: Although commonly called "hair follicle tests", this test actually evaluates the hair strand rather than the follicle beneath the scalp.
