The laboratory testing services facilitates to accurately find the presence of drug contents in the specimen. Professional home drug testing kits providers are offering laboratory testing services for confirming the test results at their selected labs. The tests conducted in the laboratories will reassure the test results that can be highly reliable. Many laboratories today are highly automated. Therefore, the test results can be known within 1 or 2 days and 2-5 days for GC/MS confirmation results.
In laboratory testing services, the specimen will be sent to laboratories for reassuring the test results. The main advantage of drug testing at laboratories is that you can carry out both the screening stage and confirmation stage at on place itself. Therefore, you can acquire fully confirmed results for your drug test.
Procedure of Laboratory Testing
The drug testing procedure with the laboratories undergoes in two stages. The first is the screening stage done by the immunoassay. If the test results positive, then it goes through the second stage i.e., confirmation stage. In this stage the specimen will be tested with the help of mass spectrometry. It is much precise but is an expensive method to use.
In this process, a comprehensive Chain of Custody (CoC) file of the specimen will be maintained from the time of specimen collection to the time of testing and reporting. It requires the signatures of the donor, collector, the courier and the laboratory personnel involved in the process.
Methods Used In Laboratory Testing Services
The laboratory confirmation tests use two industry-standard methods to determine the presence of drugs in a specimen. They are:
• EMIT Method: The EMIT (Enzyme Multiple Immunoassay Test) assay method is the commonly used for detecting the presence of drug substances in the specimen. It is used for testing five different drugs with the help of current standard. This test contains the standard cutoff point of 50 ng/ml. It makes use of a spectrometer to check the conversion process of enzymes and provides the means to measure particular drug metabolites.
• GC/MS Method: The GC/MS (Gas Chromatography Mass Spectrometer) is the drug testing method, which is administered only when the EMIT method produces positive results. In this method, a solution will be added in the specimen to convert the drug metabolites into a form that is reactive to Gas Chromatography. The sample is converted to gas at distinct intervals and then collected to isolate drug metabolites in the sample.
The above information illustrated the importance of the laboratory testing services for confirming the test results.
