Hair Follicle Drug Testing - Lakewood Heights, TX

What it is, How it works

Hair testing has emerged as a potent method for identifying drug and alcohol consumption. Hair captures a long-term record of alcohol and drugs by embedding biomarkers within the fibers of the expanding hair strand. When taken near the scalp, hair can offer a detection timeframe of up to around 3 months for alcohol and other drugs. Hair collection is straightforward, somewhat hard to tamper with, and simple to transport.

A 1.5-inch section of roughly 200 hair strands (approximately the size of a #2 pencil) closest to the scalp will yield 100mg of hair, which is the optimal sample for analysis and verification. For EtG, add-ons, and/or tests exceeding 10 panels, a 150mg specimen is advised. We suggest weighing the specimen on a jeweler’s scale. If scalp hair is not available, a similar amount of body hair might be used. When mentioning head hair, we refer exclusively to scalp hair. Body hair pertains to any other hair type (facial, axillary, etc.).

Process Overview

The primary steps in the laboratory processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of the initial processing of a sample into a laboratory’s system. This step includes confirming the sample was sealed and dispatched correctly, assigning an arbitrary LAN (Laboratory Accessioning Number), and filling in any additional data entry not covered by an electronic chain of custody system.

Screening includes an initial rapid check for drugs of misuse. While Screening is a cost-effective means to eliminate drug use on most samples, a positive screen must be validated to be permissible in court. Any samples that test presumptively positive in Screening need a secondary confirmation.

If a sample tests presumptively positive in the Screening phase, more hair is extracted from the initial sample and prepared for Extraction. During this phase, drugs are extracted from hair at much lower concentrations than in other methods (e.g., urine or oral fluid), which is why hair drug screening is the most challenging technique to execute.

Confirmation of any positive screening result is carried out through GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples are cleansed before confirmation as required. The entire laboratory procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a shorter detection duration.
• Challenging to cheat: It is quite challenging to tamper with a hair drug test, thus ensuring more accurate results.
• Offers historical data: It can reveal a pattern of drug use over time, not just recent consumption.

Limitations:

• Cannot detect recent use: Drugs require roughly 5-7 days to be identifiable in hair.
• Cost: Hair drug tests are typically pricier than other drug testing techniques.
• Result variations: Elements such as hair color and individual differences in hair growth can influence the concentration of drug metabolites in the hair.

Note: Although often termed "hair follicle tests", the test itself examines the hair strand and not the hair follicle under the scalp
