How Much Does a Hair Follicle Test Cost?

The cost of a hair follicle drug test typically ranges from $100 to $200. This price can fluctuate based on several factors, including the laboratory performing the test, the number of substances being screened for, and any additional services requested, such as expedited results or expert witness testimony. Now, let’s delve deeper into the nuances of hair follicle testing and answer some frequently asked questions.

Understanding Hair Follicle Drug Testing

Hair follicle drug tests are a sophisticated method of detecting drug use over an extended period. Unlike urine tests, which typically detect drug use within the past few days, hair tests can detect drug use up to 90 days prior, sometimes even longer. This makes them a valuable tool for employers, legal professionals, and individuals seeking a comprehensive history of substance use.

The Science Behind Hair Testing

The process works by analyzing a small sample of hair, usually about 1.5 inches in length, cut close to the scalp. As hair grows, it absorbs substances from the bloodstream, including drug metabolites. These metabolites become trapped within the hair shaft, providing a historical record of drug use. The laboratory then uses sophisticated analytical techniques, such as gas chromatography-mass spectrometry (GC-MS) or liquid chromatography-mass spectrometry (LC-MS), to identify and quantify the presence of these substances.

Factors Influencing the Cost

As mentioned earlier, several factors contribute to the overall cost of a hair follicle test:

• Laboratory Fees: Different laboratories have different pricing structures. Larger, more established labs often charge more due to their advanced technology and rigorous quality control measures.

• Panel of Drugs Tested: The number of drugs included in the screening panel significantly impacts the cost. A standard 5-panel drug test, which typically includes marijuana, cocaine, opiates, amphetamines, and phencyclidine (PCP), will generally be less expensive than a more comprehensive panel testing for a wider range of substances, such as synthetic opioids or designer drugs.

• Turnaround Time: If you require expedited results, you can expect to pay a premium. Standard turnaround times for hair follicle tests are typically 3-5 business days, but some labs offer expedited services for an additional fee.

• Confirmation Testing: If the initial screening test yields a positive result, a confirmation test is usually performed to verify the accuracy of the findings. This confirmation testing adds to the overall cost.

• Location: Prices may vary based on geographic location. Labs in urban areas or regions with higher operating costs may charge more than those in rural areas.

• Collection Fees: Some testing facilities charge a separate fee for the collection of the hair sample. This fee covers the cost of the trained personnel and materials required for proper sample collection.

Frequently Asked Questions (FAQs) about Hair Follicle Testing

Here are 12 frequently asked questions about hair follicle tests to provide you with a deeper understanding of the process, accuracy, and implications.

1. How accurate are hair follicle drug tests?

Hair follicle drug tests are generally considered to be highly accurate, with reported accuracy rates exceeding 99% when performed correctly. However, like any laboratory test, there is always a small margin for error. Factors such as improper sample collection, laboratory errors, or cross-contamination can potentially affect the accuracy of the results. Confirmation testing is crucial to minimizing the risk of false positives.

2. Can I fail a hair follicle test from secondhand smoke?

It’s highly unlikely to fail a hair follicle test from secondhand smoke exposure. The concentration of drug metabolites in secondhand smoke is typically too low to be absorbed into the hair shaft in sufficient quantities to trigger a positive result. However, consistent and prolonged exposure to heavy secondhand smoke might theoretically lead to a detectable level, but this is a rare occurrence.

3. How far back does a hair follicle test go?

A standard 1.5-inch hair sample can typically detect drug use for up to 90 days prior to the test date. Since hair grows at an average rate of approximately 0.5 inches per month, each half-inch of hair represents about a 30-day window. By analyzing different segments of the hair shaft, laboratories can potentially determine the approximate timeframe of drug use.

4. Does hair color or hair treatment affect the results?

The impact of hair color or hair treatment on hair follicle test results is a subject of ongoing debate. Some studies suggest that bleaching, dyeing, or perming hair can potentially affect the detection of certain drugs by damaging the hair shaft and washing away some of the metabolites. However, other studies have found that these treatments have minimal impact on the overall accuracy of the test. It’s important to inform the testing facility about any recent hair treatments to allow them to account for potential interference.

5. Can I use body hair for a hair follicle test?

While body hair can be used for hair follicle testing, it is generally not preferred over head hair. Body hair grows at a slower and more variable rate than head hair, making it difficult to accurately determine the timeframe of drug use. Additionally, body hair is more susceptible to external contamination. If head hair is not available, body hair can be used, but the results may be less precise.

6. What drugs can be detected by a hair follicle test?

Hair follicle tests can detect a wide range of drugs, including:

• Marijuana (THC)
• Cocaine
• Opiates (heroin, morphine, codeine, oxycodone, hydrocodone)
• Amphetamines (methamphetamine, amphetamine)
• Phencyclidine (PCP)
• Synthetic opioids (fentanyl, tramadol)
• Benzodiazepines
• Barbiturates
• Ecstasy (MDMA)

The specific panel of drugs tested will vary depending on the requirements of the employer or legal entity requesting the test.

7. How is the hair sample collected?

The hair sample is typically collected by a trained technician. They will cut a small amount of hair, usually about 40-60 strands, from the back of the head, close to the scalp. The hair is usually taken from multiple locations to minimize any noticeable thinning. The sample is then placed in a secure collection container and sent to the laboratory for analysis.

8. What happens if I shave my head before a hair follicle test?

Shaving your head in an attempt to avoid a hair follicle test is generally not advisable. While it may temporarily prevent the collection of a head hair sample, the testing facility can still request a body hair sample. Additionally, attempting to tamper with a drug test can have serious consequences, including job loss or legal penalties.

9. Are there any ways to cheat a hair follicle test?

There are numerous products and methods marketed as ways to “detoxify” the hair and pass a hair follicle test. However, most of these products are ineffective and can even damage the hair. Attempting to cheat a drug test is risky and can result in serious repercussions. Honesty and transparency are always the best approach.

10. What are the legal implications of a positive hair follicle test?

The legal implications of a positive hair follicle test will vary depending on the specific circumstances. In employment situations, a positive test can lead to disciplinary action, including termination of employment. In legal cases, a positive test can be used as evidence of drug use, which can have implications for custody disputes, probation violations, or other legal matters.

11. How long does it take to get the results of a hair follicle test?

The turnaround time for hair follicle test results typically ranges from 3 to 5 business days. However, some laboratories offer expedited services for an additional fee, which can reduce the turnaround time to 24-48 hours.

12. Where can I get a hair follicle test done?

Hair follicle tests can be obtained through various sources, including:

• Drug testing laboratories: These labs specialize in drug testing services and often offer a wide range of testing options.
• Occupational health clinics: These clinics provide medical services to employers and employees, including drug testing.
• Medical clinics: Some medical clinics offer drug testing services as part of their routine healthcare offerings.
• Online testing providers: There are online companies that offer at-home drug testing kits, including hair follicle tests. However, it’s important to choose a reputable provider with a certified laboratory.

In conclusion, understanding the cost factors, accuracy, and implications of hair follicle testing is crucial for making informed decisions. While the price typically falls between $100 and $200, the value of the comprehensive drug use history it provides can be invaluable in various situations.
