Overview of Hair Follicle Drug Testing

This method of drug testing is highly accurate and can detect a wide range of substances over an extended period.

How Accurate is Hair Drug Testing?

Hair follicle drug testing is one of the most accurate methods available. It can detect drug use for up to 90 days prior to the test. The accuracy of this test is due to the way drugs are metabolized and stored in the hair shaft, providing a long-term record of substance use.

Hair Drug Test Detection Time

The detection window for hair drug testing is significantly longer than other methods. Here is a breakdown of the detection times for various substances:

• Marijuana: Up to 90 days
• Cocaine: Up to 90 days
• Opiates: Up to 90 days
• Methamphetamines: Up to 90 days
• Phencyclidine (PCP): Up to 90 days

Hair Sample Collection Process

The hair sample collection process is straightforward and non-invasive. Here’s what you can expect:

1. Preparation: No special preparation is needed. Simply arrive at our facility.
2. Collection: A small sample of hair (about 1.5 inches) is cut from the scalp. This sample is usually taken from the back of the head to ensure it is not noticeable.
3. Sealing: The hair sample is then sealed in a tamper-evident container and sent to the lab for analysis.

Hair Drug Test vs. Urine Test

While both hair and urine tests are commonly used for drug screening, they have distinct differences:

• Detection Window: Hair tests can detect drug use for up to 90 days, whereas urine tests typically detect drug use within the past few days to a week.
• Accuracy: Hair tests are generally more accurate and harder to tamper with compared to urine tests.
• Invasiveness: Hair tests are non-invasive, while urine tests require a sample to be provided in a controlled environment.

Hair Drug Test for Employment

Many employers use hair follicle drug testing as part of their pre-employment screening process. This method provides a comprehensive view of an applicant’s drug use history, ensuring a safer and more productive workplace. At Fastest Labs SE San Antonio, we offer quick and confidential testing to meet your employment screening needs.

Hair Drug Test Preparation

Preparing for a hair drug test is simple. There are no special requirements or restrictions. However, it is important to note that hair treatments such as dyeing, bleaching, or perming do not affect the results of the test. Simply ensure your hair is clean and free of any heavy styling products on the day of the test.

Hair Drug Test Results Interpretation

Interpreting the results of a hair drug test can be complex. Our team at Fastest Labs SE San Antonio is here to help. Here’s a basic guide to understanding your results:

• Negative: No drugs were detected in the hair sample.
• Positive: Drugs were detected in the hair sample. The report will specify the type and amount of drugs found.
• Inconclusive: The test could not determine a clear result. A retest may be necessary.

Hair Drug Test for Court Cases
