Hair Follicle Drug Testing Services in Rock Hill, SC

Hair follicle drug testing is a method used to detect the presence of drugs and alcohol in an individual's system. Unlike other testing methods, hair follicle tests can provide a longer detection window, making them ideal for various applications, including employment screening and legal cases.

How Accurate is Hair Drug Testing?

Hair drug testing is known for its high accuracy. The test can detect a wide range of substances, including but not limited to:

• Marijuana
• Cocaine
• Opiates
• Methamphetamines
• Phencyclidine (PCP)

Due to its ability to detect drug use over a longer period, hair follicle testing is less likely to be affected by short-term abstinence or attempts to cheat the test.

Hair Drug Test Detection Time

One of the key advantages of hair follicle drug testing is its extended detection window. Typically, hair drug tests can detect drug use for up to 90 days. This is significantly longer than urine tests, which usually detect drug use within the past few days to a week.

Hair Sample Collection Process

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

1. A small sample of hair (about 1.5 inches) is cut from the scalp.
2. The sample is then sealed in a secure container and sent to a laboratory for analysis.
3. The entire process takes only a few minutes and is conducted under strict chain-of-custody protocols to ensure the integrity of the sample.

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 less likely to be affected by short-term abstinence or attempts to cheat the test.
• Invasiveness: Hair sample collection is non-invasive compared to urine sample collection.
