Morphine is natural opium which occurs as white crystals or white powder and has bitter taste and alkaline reactions. When orally ingested, it is well absorbed by the intestines and this first pass metabolism is bypassed if morphine is injected and the time interval between the intake of drug and the appearance of drug in blood is very minimal. Still urine remains to be the most effective specimen for the testing the presence of morphine in the body. But it can also be recovered from blood and bile. (more…)

Rapid drug screening should be done after a careful choice of the sample that will be used for the qualitative analysis. The choice of the test method will decide on the sample that will be collected for the drug info screen. The drug screen can be a urine drug screen or a saliva drug screen based on the testing pattern that is most suitable for the detection.

In any drug screen test the best choice of sample, collection, storage, analytical pattern and time frame for the analysis should be pre-determined. The major factor that will interfere in this decision making will be specificity of the assay. Specificity of any drug testing methodology is the competency of the test assay to identify the presence of the compound in the presence of other components that might probably cross react. The level of accuracy and the precision of the test method will be influenced by degradants, metabolism, impurities and the biological matrix.

The drug screening method has 2 steps, one is the preliminary analysis and the next is the confirmatory analysis. The preliminary analysis is mostly rapid and it will provide with a qualitative analysis which will indicate the presence of absence of a compound in the sample. Pseudo-qualitative analysis will dictate the presence or absence of a compound based on a pre-determined cutoff level. The rapid drug screening method analyses the major drug class and the exact drug entity will be identified by the confirmatory analysis. Most of the preliminary testing methods are onsite and can be done with test strips and instant testing methods that are mostly of the dipstick type that declares positives and negatives.

The rapid drug screening method detects the drugs by using antibodies that binds to the binding site of the target drug. The binding site design is unique to a particular class of drugs and the immunoassay is based on with the antibiotics that will bind to the target binding sites of the drug that is being targeted for identification by using that particular assay. A positive result for any drug testing method in an immunoassay indicates the drug to be positive, which is in all cases above the cut off concentration for the assay. Such a positive warrants further confirmatory tests. The purpose of having a cutoff concentration is to limit the number of false-positives caused by the interference by cross reacting substances.

Collection of samples, taking it to the laboratory, waiting for the results to be listed- these are the various sequence of steps associated with the drug testing. Though economical sometimes, they are always time consuming. The best alternative is the rapid drug testing using drug instant kit test. All these testing devices are small, compact, easy to use and reliable. The results can be obtained instantaneously and above all for a large number of samples in a short duration of time. This would be of great help to the companies where drug testing comprises of testing a several samples at a given time.

The panel drug test can be done for a single drug or for a number of drugs at a given time. Single test cards consist of single test strip which can be specific for THC (marijuana), cocaine, or oxycodone or nicotine. The panel can also consist of more than one strip that detects more than one drug at a time. it can be 4 panel or 6 panel strips which are only for the qualitative analysis of drug.

Rapid drug detection can be done using adulterant test and breathalyzer. These rapid drug detection kits are composed of a testing unit that is coupled with the sample analyzing portion that comes in contact with the sample. The analyzing unit has the in built testing materials that assess the sample. In case of the test strips the presence of the drug can be seen by a change in color of the test strip. Always there are inbuilt positive and negative controls.

Rapid drug screening is also prone for false positive and false negatives that have to be carefully monitored. The best way of having a fool proof mechanism is to checking for the approved standards in the drug testing devices that you plan to buy. They must conform to the standards of FDA or SAMHSA or CLIA.

Rapid drug screens are effective both in terms of cost as well as time. They are done using disposable kits that are eco friendly. They provide accurate results especially for the employers who cannot spend extra time in going to the lab and getting the samples tested. Further the tests can be performed at any time irrespective of the place as they are portable and compact. Bed side testing of samples can also be done using rapid drug detection testing devices.
