Hair testing is increasingly recognized as an effective means of detecting drug and alcohol consumption. Hair captures a long-term record of alcohol and drugs by encasing biomarkers in the hairs as they grow. When taken near the scalp, hair can offer a detection timeframe of around three months for alcohol and drugs. It is easy to gather, somewhat hard to falsify, and straightforward to send.
A sample measuring 1.5 inches comprising roughly 200 hair strands (about the size of a #2 pencil) nearest the scalp yields 100mg of hair, which is the optimal sample for analysis and confirmation. For EtG, additional tests, and those over 10-panel tests, it is ideal to have 150mg of the sample. We suggest weighing the sample on a jeweler’s scale. If scalp hair is missing, a similar quantity of body hair can be collected. When discussing head hair, we mean scalp hair specifically. Body hair encompasses all other hair kinds (facial, axillary, etc.).
Process Overview
The crucial steps in laboratory processing of a drug test result consist of Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary handling of a specimen into a laboratory system. This includes checking that the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not included by an electronic chain of custody system.
Screening is a fast preliminary check for the presence of drugs. Although Screening is an economical way to dismiss drug usage in most samples, a positive result must be confirmed for it to be valid in court. Samples that show a presumptive positive result in Screening require further confirmation.
If a sample tests positive during Screening, more hair is extracted from the original sample to prepare for Extraction. During this stage, drugs are extracted from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), explaining why hair drug screening is among the toughest methods to conduct.
Any positive Screening outcomes must undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing presumptive positives are washed as necessary before Confirmation. The whole process from Accessioning to Confirmation is assessed in line with the CAP (College of American Pathologists) Hair designation and adheres to ISO/IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although commonly called "hair follicle tests," the testing procedure involves the hair strand rather than the hair follicle located under the scalp.
In Cedarhurst, MD, hair follicle testing is increasingly favored over urine testing due to its superior ability to pinpoint substance use. Hair tests typically provide a more accurate reflection, as they capture a longer period of drug consumption history. This method is less susceptible to manipulation, thus, offering a more reliable alternative for detecting drug use.
In Cedarhurst, MD, one remarkable advantage of hair follicle testing is its extended detection window. This method can trace drug use activities up to 90 days prior, providing employers an extensive overview of an individual's substance history, which is indispensable for making informed employment decisions.
Hair follicle testing in Cedarhurst, MD, offers an inherently tamper-resistant approach to drug screening. By cutting a small sample of hair, this method minimizes opportunities for adulteration, ensuring that results remain consistent and credible, which is critical for maintaining trust in drug-free environments.
