What is being analysed?

Marijuana (THC) analysis examines the presence and quantity of delta-9-tetrahydrocannabinol (THC), the psychoactive compound in cannabis, in a biological sample.

What does the result mean?

The result indicates the concentration of THC present in the sample. It helps determine if an individual has recently used marijuana and provides insight into their level of exposure to THC.

Why do the analysis?

The analysis is performed for various reasons, including monitoring drug use, evaluating intoxication levels, assessing compliance with legal or workplace regulations, and assisting in medical treatment decisions.

When to do the analysis?

Marijuana (THC) analysis is typically conducted when there is suspicion of recent marijuana use, such as in forensic investigations, workplace drug testing, medical evaluations, or monitoring treatment compliance.

What sample is required?

The most common samples for THC analysis include urine, blood, saliva, and hair. The choice of sample depends on factors such as the detection window needed and the ease of sample collection.

Is any type of prior preparation necessary?

No specific prior preparation is required for the individual undergoing THC analysis. However, proper collection, handling, and storage of the sample are essential to ensure accurate results.

How is it used?

The sample is collected following standard procedures and then analysed using techniques such as gas chromatography-mass spectrometry (GC-MS) or immunoassays to quantify THC concentration.

What are the normal values?

Normal THC values depend on various factors, including the type of sample, frequency of marijuana use, and individual metabolism. In general, for workplace drug testing, concentrations above a certain cutoff level (e.g., 50 ng/mL in urine) are considered positive.

What does it mean to have altered values?

Altered THC values indicate recent marijuana use or exposure to cannabis products containing THC. Depending on the context, elevated THC levels may suggest intoxication, non-compliance with regulations, or potential health implications.

In summary, Marijuana (THC) analysis provides valuable information about an individual's recent marijuana use or exposure to THC-containing products. Understanding the significance of the results and the appropriate contexts for testing is crucial for accurate interpretation and informed decision-making.
