What is an I Drug Screen?

An I Drug Screen is a blood test that can determine the presence of drugs in a person’s system. It can detect many different types of drugs, including opiates, benzodiazepines, cannabinoids, amphetamines, and more. Most commonly, the test detects cocaine, marijuana, and opiates, but there are also other types of drugs that can be detected.

Concentra on the I Drug Screen

Concentra is a drug testing company that offers an initial panel drug test. They then send the results to a third-party laboratory for further analysis. This method is also known as outsourcing and enables them to screen a wider variety of substances and get data from a variety of samples. Some of these samples are taken from hair or urine, which can indicate drug use that occurred months or years ago. Regardless of the method of testing, the process is quick and easy.

Concentra is the third largest drug testing company in the US. This company offers drug test results and specialist products. These tests cover a variety of substances, including methamphetamine. They also have specialist products that cover false positives.


I Drug Screen tests are a way to check for the presence of illegal or prescription drugs. They can detect the presence of marijuana, cocaine, opiates, amphetamines, PCP, barbiturates, and other substances. These tests are usually performed in two steps, with a short at-home test followed by further testing in a lab.

The process of taking a drug test is not painful or invasive. However, it can lead to legal problems. For example, drug use may affect a person’s ability to work in a particular profession. For this reason, you should always prepare before undergoing a drug screening test.

Pre-testing session

A pre-testing session is an opportunity for you to get a better understanding of how the drug testing process works. In many cases, large organizations and corporations will ask you to attend a pre-testing session before requiring a more formal drug test. The goal of a pre-testing session is to save both time and money by eliminating the need to travel to a testing center.

False positives

False positives on an I drug test can be caused by substances found in over-the-counter medications. For instance, codeine and pseudoephedrine, which are often found in over-the-counter cold and flu medication, can both cause false positives on drug tests. These substances can also alter the results of an instant rapid test. However, most false positives are correctable with an alternate screening methodology.

One way to combat false positives is to disclose what substances you have used in the past few weeks. This can help the lab verify your results. It is also helpful to inform your employer, principal, or coach about your situation. It may help convince them to give you another chance. Alternatively, you can request a confirmation test to prove the results of the initial test. These tests are often more reliable than the original ones, but they are expensive and require specialized equipment.


You may have received a positive drug screen result and need to schedule a retest. This can be both frustrating and confusing. You will have to wait until the results are returned from the lab before you know if your employee is clean or not. In many cases, the employee will have to notify the laboratory about any medications they are taking and must provide a copy of their current prescription and the prescribing physician’s information. The medical review officer will contact you to discuss the results.

You can request a retest within 72 hours of receiving your first drug screen result. Some labs save a portion of your sample to use for retesting. You can make your request orally or in writing. If your retest is positive, you must pay for a retesting. The medical review officer will inform the lab that you have requested a retest.

Federal employees

If you are applying for a job with the federal government, you might be asked to undergo a drug test. The process may be pre-employment, “on reasonable suspicion,” “for cause,” or routine. The tests may include breathalyzers, saliva samples, or hair samples. The results may be confidential.

All federal employees are subject to drug testing, but some employees may be exempted from the testing because they have certain clearances. This is true of some employees with top-secret clearances, including some who work in the Hoover Building, but not of all.
