What Is the Chain of Custody Protocol in Laboratory Testing

Repairable errors are errors in the testing process that need to be corrected. Otherwise, the drug test must be cancelled. If you hire a new driver, you will need to pass an FMCSA drug test before hiring. There are a few steps to get it right. They are as follows: Accesa Labs offers eCCF tests. This modernized digital version is much easier and more efficient to use than traditional five-part paper tests. An Electronic Custody and Control Form (eCCF) is the digital version of the traditional five-part paper custody and control form – the document used to order drug testing, process samples, and document the chain of custody for drug testing in the workplace. The CCF documents the external sampling chain, i.e. the handling of the drug test body from collection to laboratory acceptance. For this reason, at least for DOT drug testing, the employer has a copy of the chain of custody form.

Assuming the employer has a well-informed DER, they can carefully check the CCF for errors. We will discuss later the errors that the CCF can report. For Department of Transportation (DOT) drug testing, this is the procedure of documenting the management and storage of a sample from the time a donor provides the sample (usually urine) to the collector at the final destination of the sample and the verification and reporting of the final test result. It is, of course, imperative that information about the CCF be clear, complete and concise so that a result can be reported quickly and accurately. Even with the CCF, MROs, labs, collectors, employers, and even donors can find errors in the testing process that might otherwise have gone unnoticed. You can then correct the error or cancel the test. In this way, they can prevent false alarms. A, B, C, D and E should all sign the chain papers, and the prosecution should testify to each person in the chain to identify and determine the status of the evidence showing that the defendant abused cocaine.

The MRO will record its final result on the completed CCF and will also be able to transport this result electronically with a specific results reporting software. Throughout the process, part or a copy of the form can be kept by the sample collector, the organization to be tested, the distributor, the laboratory and finally the MRO, the MRO copy recording the final result. As mentioned earlier, each party receives its own copy of the chain of custody form: especially for urine drug abuse testing, it is important that the donor identifies the sample and that the cup of urine is sealed in front of the donor, followed by the person who took the sample who signs the chain of custody forms. (In the case of an unconscious patient in the emergency department, the nurse who collects the urine sample can identify it at the patient`s location.) Here`s an example of what might happen next: Missing or incorrect information can lead to unnecessary delays in the process and, in some cases, lead to the cancellation of the entire test request. For example, if the sample ID# written on the top of the CCF does not match the sample ID# on the sample vial, the test facility (the laboratory) reports a rejected for testing result. This particular task falls to the collector, as well as various other sections on each of the 5 copies of the CCF. Typically, for DOT tests, there are 5 parts or copies to a federal CCF.

Usually, urine drug tests performed during medical tests are performed with immunoassays. Confirmation using another analytical method such as GC/MS or MS tandem chromatography can only be performed at the request of the attending physician. Donors have already presented properly issued government-issued identification (driver`s license, passport, government-issued ID card, etc.) upon arrival at the test site. In addition, they must confirm their identity as part of the Chain of Possession drug testing process. This way, the test center knows who you are and can proceed with certainty. The chain of custody is the movement and location of physical evidence from the time it is obtained until it is presented to the court and used to prove the integrity of evidence. To track the chain of custody, a written record is kept so that employees who are in possession of the evidence at different times can be easily identified and summoned to testify during the trial if necessary. .
