檢測棒ct意思

"CT" in the context of a "檢測棒" (detection stick or test strip) typically stands for "Cannabinoid Tetrahydrocannabinol" or simply "THC." THC is the primary psychoactive component found in cannabis (marijuana) that produces the feeling of being "high."

A THC detection stick is a tool used to quickly and presumptively detect the presence of THC or its metabolites in a person's system. These tests are often used for workplace drug testing, law enforcement, or personal use to determine if someone has recently used cannabis.

The test works by collecting a sample, usually saliva or urine, and reacting it with antibodies that are specific to THC. If the sample contains THC, the antibodies will bind to the THC, and a visual line will appear on the test strip, indicating a positive result.

It's important to note that these tests are not as precise as laboratory tests and can sometimes produce false positives or negatives. Additionally, the detection period for THC can vary greatly depending on factors such as frequency and amount of use, individual metabolism, and the type of test used.
