The Art of Mastering Tests

Popular Drug Testing Methods

There are numerous types of ways of testing for drugs. The most common involves using samples of blood, urine, and saliva which is analysed. These substances are used to detect any levels of metabolites which tells whether you have used any drug substance recently. Metabolites are stored in the body in the fatty cells and the growing cells. over time, the excretion of these metabolites happens in the body and through the urine.

It does not take so long before the metabolites are leached out of the bloodstream. There are some factors that affect the rate of excretion which include the level of activity and the amount of fat a person has in the body. the presence of metabolites in the hair has been noted in the recent past. Time taken for metabolites to show up in the hair is approximately five days.

No drug test has ever been found to be entirely perfect. However, over time, urine analysis has been popularly used to test for drugs. urine kits are the devices used to test drugs in the body and have become very popular recently. One disadvantages of using the urine analysis is how easy it is to manipulate results. To eradicate the vice of manipulation, retests are done that indicate the presence of added substances in the sample. There is no direct effect of the added substance in the sample This gives a hint that the sample has been doctored.

Drinking a lot of water will not help a person in passing a drug test. The body and the urine produce a protein by the name Creatinine The protein helps to detect attempts by a person to get rid of the drug in their bodies. Free kits for drug tests have been in the offer by many companies. Some of the things in the kits are the breathalyzers, drug test kits among others. the information of the person using the free kits is not enough because they are private.

The kits are portable devices that analyze sample of saliva blood and urine. The testing results from the reaction of the sample and the strip whose results are the changing color of the strip The absence or presence of a drug in the urine is indicated in the strip which gives the results in about two minutes. The variables of testing are only the presence and absence of the drug in the urine. The the accuracy of the kits is becoming more better due to the increased advancement and technological progress. Use of laboratory techniques is bringing a realization of more accurate results of drug testing. In a list of many laboratory tests, gas chromatography, is the commonly use. They have a comprehensive test of drugs in a given sample.
