The Different Techniques Used By marquis test kit In Drug Testing

Nowadays, we know how rampant drug usage is anywhere in the world. It doesn’t matter whether we’re talking about developing or first-world countries. The same situation happens in most countries, just varying in the severity of the problem.

However, thanks to technology, one can easily detect if a person engages in the use of recreational drugs. With the aid of drug-testing kits like the marquis test kit, one can easily find out in a snap of the finger the results of the test done. Learn more about marquis test kit on wimscilabs.

There are typically different samples used to detect the presence of drugs, chemicals and its metabolites. Here are some of the most common samples used:

a)      Urine

b)      Saliva

c)      Breath

d)      Hair follicle

e)      Blood

However, it’s safe to say that no drug-testing kit is perfect. There’s still some room for error, but, the one cannot disregard the accuracy it’s giving.

How do drug-testing kits work?

•  The body stores the by-products of the chemicals used by the person in the form of metabolites. These metabolites are then stored in fast growing cells and fatty cells, which eventually will move into the bloodstream and removed via urine.

•  However, there are metabolites that stay in the body for a period of time, with its excretion rate varying due to the following factors:

a)      Activity level

b)      Metabolism

c)      Amount of fatty tissue in the body

Types of drug-testing kits available in the market

a)       On-the-spot drug test kits

•  Portable devices that analyze a sample of the saliva, sweat or urine

•  Makes use of the binding reaction between the drug and the testing strip, resulting in a color change

•  Indicates presence or absence of a drug, not the exact amount of the drug itself

b)      Pupillometry

•  Makes use of eye responses to detect any drug or alcohol-related impairment

c)      Laboratory testing

•  Makes use of more sophisticated techniques (immunoassays)

d)      Gas chromatography

•  Most reliable test for presence of any drug

•  Can quantify the amount of drug present as well as its metabolites

•  It can also identify specific drugs including those of prescription drugs.
