With this method of screening, the lab detects a binding reaction between the target drug and/or drug metabolite and an antibody producing a signal detected by automated instruments indicating whether the target compound might be present in the specimen. This is the initial screening of the urine specimen. Now is when the testing begins with an enzyme immunoassay (EIA) methodology often called an emit screen. What Happens at the Lab?Įach morning, the lab receives the specimens collected the previous day. Specimens picked up today will typically arrive to the lab very early the next morning. The specimen is then shipped to the laboratory via FedEx, UPS, lab courier system, or any combination of these. The urine specimen collected is sealed with a security seal containing a unique specimen ID number that will also be present on the paper or electronic CCF. The employer or other party ordering the test gives the donor an electronically produced order form (donor pass), an authorization form, or the actual 5-part carbonless CCF. There are strict custody-and-control procedures with the use of a 5-part carbonless custody-and-control form (CCF) or the use of electronic collection on a computer system called e-CCF. The laboratory and collection site are separate facilities in separate locations. The donor will then go to a facility called a collection site where their urine specimen is collected and prepared to be shipped to the laboratory. An employer or some other party orders the test and specifies the individual to be tested, i.e., the donor. Let us start with the basic process of how a urine specimen is tested for drugs. Specimen Collection of the Urine Sample for Drug Testing This test could be a five-panel test, a ten-panel test, or one of many others. ![]() When ordering a test, the ordering party must specify what test they want the lab to perform. The testing process can be initiated by any of the following (ordering parties) and often others: The process for each of these parties will be reviewed here. The process involves parties including the specimen collector, laboratory, and medical review officer (MRO). In this blog post we will talk about laboratory drug testing with a urine specimen and answer the question of what happens when a urine specimen goes to the lab for drug testing. Most drug testing in the United States involves a laboratory receiving and testing urine, oral fluid, hair, or blood specimens. ![]()
