Hair Follicle Drug Testing - Mcnair, TX

What it is, How it works

Hair testing is increasingly recognized as a robust method for identifying drug and alcohol consumption. Hair samples offer an extended record of alcohol and drug usage by capturing biomarkers within the hair strand's fibers as it grows. When gathered near the scalp, hair can detect substances for up to a quarter of a year. Hair collection is straightforward, hard to tamper with, and simple to transport.

A sample measuring 1.5 inches, consisting of roughly 200 hair strands (similar in size to a #2 pencil) close to the scalp, produces 100mg of hair, which is ideal for both screening and confirmation. For EtG, additional tests, and those beyond 10 panels, 150mg of the sample is preferred. It's advisable to measure the sample using a jeweler’s scale. If scalp hair cannot be obtained, an equivalent quantity of body hair may be used. 'Head hair' specifically indicates scalp hair, while 'body hair' encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result comprises four essential phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary phase where a sample is entered into the lab's system. This step ensures the sample was properly sealed and transported, assigns it a random LAN (Laboratory Accessioning Number), and finalizes any extra data entry that an electronic chain of custody system may not include.

Screening serves as an initial, efficient review for substances of misuse. Although Screening is economical for the majority of samples, a positive result must be confirmed for legal acceptance. Samples presenting a preliminary positive in Screening require further verification.

During Screening's presumptive positive outcome, additional hair is extracted from the initial sample and prepared for Extraction. In this phase, drugs are isolated from hair at significantly lower concentrations than other techniques (such as urine or oral fluid), which presents hair drug screening as the most challenging method.

For confirming any positive Screening finding, GC/MS, GC/MS/MS, or LC/MS/MS techniques are employed. All presumptive positive samples receive a pre-confirmation wash when required. The thorough process from Accessioning to Confirmation is assessed according to the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extensive detection period: Hair drug tests can track drug use for up to 90 days, in contrast to urine tests which have a limited detection period.
• Resistance to tampering: Cheating a hair drug test is extremely challenging, thus enhancing the accuracy of the results.
• Historical insights: It offers a history of drug use over an extended duration, beyond just immediate use.

Limitations:

• Lacks recent use detection: It takes about 5-7 days for drugs to become traceable in hair.
• Expenses: Generally, hair drug tests incur higher costs than alternative testing methods.
• Result variability: Hair color and individual differences in hair growth can influence the levels of drug metabolites in the hair.

Note: Commonly termed as "hair follicle tests", the test evaluates the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In McNair, TX, hair follicle testing stands superior to traditional urine tests. It offers an extensive detection period and high reliability.
