Hair Follicle Drug Testing - San Antonio, TX

What it is, How it works

Hair analysis is increasingly appreciated as an effective method for identifying drug and alcohol consumption. Hair retains a prolonged record of alcohol and drug intake by embedding biomarkers into the fibers of the strands as they grow. When clipped near the scalp, hair can reveal a detection window for alcohol and drugs of up to about three months. Collecting hair is straightforward, relatively hard to tamper with, and simple to send.

A 1.5-inch segment comprising roughly 200 hair strands (resembling a #2 pencil in size) nearest to the scalp will yield 100mg of hair, which is the optimal amount for screening and confirmation. For additional tests like EtG or those exceeding 10 panels, 150mg of the sample is advisable. It's suggested to weigh the sample using a jeweler's scale. Should scalp hair be unavailable, an equivalent portion of body hair can be collected. "Head hair" refers solely to scalp hair, whereas "Body hair" encompasses all other types (e.g., facial, axillary).

Process Overview

The laboratory procedure for obtaining a drug test outcome consists of four vital steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial handling of a sample within a laboratory's framework. This process ensures that the sample was sealed and sent correctly, assigns a unique LAN (Laboratory Accessioning Number), and performs any supplementary data input not managed by an electronic chain of custody system.

Screening incorporates a preliminary swift assessment for drugs of misuse. Although Screening is an economical approach to exclude drug use in most samples, a positive screening outcome must be corroborated to be valid in legal settings. Samples with a presumptive positive from Screening necessitate further confirmation.

Should a sample reveal a presumptive positive during Screening, additional hair is extracted from the original sample for Extraction. In this step, drugs are isolated from the hair at significantly lower concentrations compared to other techniques (e.g., urine or oral fluid), rendering hair drug testing the most challenging method to conduct.

Confirmation of any positive screening outcome is carried out using GC/MS, GC/MS/MS or LC/MS/MS. Essential cleaning of all presumptive positive samples takes place before confirmation. The laboratory process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection timeline: Hair drug tests can identify drug use for up to 90 days, unlike urine tests with a shorter detection period.
• Challenging to falsify: It is exceedingly hard to tamper with a hair drug test, ensuring more precise results.
• Supplies historical insight: It offers a record of drug consumption patterns over a time span, instead of only recent usage.

Limitations:

• Inability to detect recent consumption: It takes about 5-7 days before drugs become detectable in hair.
• Expense: Hair drug tests usually cost more than other drug testing methods.
• Outcome variability: Elements such as hair color and personal variations in hair growth can influence the level of drug metabolites in the hair.

Note: Despite often being termed "hair follicle tests", the analysis investigates the hair strand, not the follicle beneath the scalp.
