Have you been searching "hair follicle drug test near me" online? What is a hair follicle drug test, exactly?

Hair drug testing was first adopted by employers as the "executive level" method for employment drug testing. To this day, hair drug testing has proven its effectiveness and continues to play a vital role in ensuring security and safety within our nation’s workplaces. It's a bulletproof way to keep drug use at bay.

Hair follicle drug testing presents many advantages over other types of drug testing. However, it's essential to recognize its strengths and limitations.

How Does Hair Testing Work?

First, let's talk about how drugs even end up in a hair sample.

How Drugs Reach Your Hair

After someone engages in drug use, the substances get metabolized. Then, the drug metabolites are absorbed into the user’s bloodstream. Humans have millions of hair follicles throughout the head and body. And each hair follicle has a blood vessel that feeds the growth of the hair strand.

The drug metabolites, after use, are carried from the blood into the hair shaft. Thanks to these drug metabolites, traces of illegal drugs can then be detected within the length of the hair strand using a hair follicle drug test.

This is how a hair follicle test can detect drugs! Drug use sends the illicit drugs into the blood and, eventually, the hair shaft.

What Does a Hair Follicle Drug Test Look Like?

Hair follicle drug testing is a quick and pressure-free experience.

How much hair does the donor need to provide hair samples?

Hair testing requires collecting a hair sample from anywhere on the body, as long as it's at least 1.5 inches in length. The hair sample cannot be provided from a brush or another unverifiable source. It must come directly from the donor.

For the drug use analysis to be effective, the collector will obtain, under direct observation, a 100-milligram sample of hair (approximately 90 to 120 strands) cut with scissors, preferably at the crown of the head. The hair strands are cut from as close to the scalp as possible. The collector can remove hairs from different spots on the head to avoid creating a bald spot.

For donors with very little or no head hair, the collector might use body hair, as deemed appropriate, for the hair test instead.

The collector will then secure the hair-strand sample in foil, complete the chain of custody documentation process, and prepare the specimen for shipment to a testing laboratory to screen for drug use.

The Benefits of Hair Drug Testing

Objective Testing That is Fully Supervised

Since hair samples are obtained under direct observation, in full view of the collector, the process nearly eliminates the likelihood of sample adulteration, specimen substitution, and false-positive results.

For this reason, a hair drug test is nearly impossible to cheat. Even if a donor uses certain shampoos or products that claim to cleanse hair follicles and help to beat the test, these products are unlikely to remove the drug metabolites from within the hair strand.

As a funny twist to cheating attempts, hair washing helps remove external contaminants, benefiting the hair testing process and making drug use even more detectable.

The Hair Follicle Drug Test Offers Superior Detection Time

When employers consider the different employment drug test methods available, they should focus on what they are trying to accomplish.

Do you want to detect long-term patterns of drug abuse in your employees? Do you prefer to collect hair samples instead of urine because hair samples are harder to cheat when it comes to detecting drug use?

Very often, many employers and other individuals end up choosing hair drug testing due to its unparalleled detection window.

Better Detection Window than Other Drug Tests

Employment drug testing methods are not all the same. They each have different detection levels (laboratory cutoff levels) and detection times — meaning how long after drug use has stopped the substance can be detected in a sample.

The window of detection is critical. It includes how soon after someone uses a drug and how long after they stop using it the drug can be found.

Hair drug test results offer a longer lookback window than a urine drug test.

In other words, hair drug testing provides the most prolonged detection period when screening for illicit drug use or prescription medication misuse compared to urine drug tests, blood tests, a sweat sample, or oral fluid (saliva) drug testing.

Testing via a hair sample will be able to detect a pattern of repeated drug use from approximately a week after the last use up to several months after the last use (one week to 90+ days).

Detection window for hair samples and other specimens for drug tests

This is why hair drug test results are so reliable and thorough.

Shortfalls of Hair Follicle Drug Tests

  • Unlike a urine drug test, hair drug tests may not be useful for monitoring compliance regularly because they cannot discriminate between recent drug use and use that occurred months earlier.

  • Popular for detecting long-term drug use, hair drug tests should not be utilized to detect recent drug use, as this method is unable to detect single use within the last three to seven days.

  • Hair follicle drug tests are slightly more expensive than other testing methods, like urine tests.

  • Unlike urine tests, there is no "instant"/point-of-collection (POCT) or overnight testing option available for the hair follicle test. All hair drug tests require laboratory analysis.

  • The turnaround time for laboratory test results is longer due to the extensive analysis process.

The Legality of the Hair Drug Test for Employees

"Is the hair drug testing near me legitimate?" you might be asking. The laboratory test results from hair testing have been routinely admitted in both state and federal courts, as well as arbitrations and agency hearings. And they are routinely upheld.

Some court systems use hair analysis and the test results of the hair follicle drug test as part of their probation, parole, and diversionary programs.

Hair follicle drug tests are not currently approved for federal/Department of Transportation (DOT) drug testing programs. Some states prohibit hair follicle tests for employee drug testing. So, the hair test drug screen isn't a good fit here.

Employers should consider state and federal laws when implementing hair test programs. Compliance experts at US Drug Test Centers can help you determine the legality of any drug testing methods in your state, including hair drug tests.

Employers throughout the United States are now implementing hair testing programs due to the benefits the hair sample offers. Order your hair follicle tests online today or call 866-566-0261.

Other Uses for Hair Testing

Many attorneys are ordering hair follicle drug tests for court-ordered drug testing, child custody, and divorce drug testing. Individuals often order hair follicle drug tests for personal reasons, such as when parents want to test their teenage children.

When this is the case, parents usually ask if a hair sample collected from a brush can be used. The answer is yes, but the test will be reported as having an "anonymous" donor.

It's not possible to attribute the hair sample to any specific person, and we cannot determine the time frame of the test, so the test result is not legally defensible.

Please note that not all of our testing centers are available for "anonymous" donor hair testing. This type of drug test is only performed at our specialty laboratories.
