Drug tests available via saliva, urine, hair and surfaces/powders. The multiple drug rapid test is a rapid urine drug test that can be performed without the use of any instrumentation. The test uses monoclonal antibodies to selectively detect elevated levels of specific drugs in the urine. The Saliva Rapid Drug Test is an immunoassay based on the principle of competitive binding. Drugs that may be present in the oral fluid sample compete against their respective conjugates for binding sites on the specific antibody. The rapid drug test is a surface or solid test that can be performed without the use of instrumentation. The test uses monoclonal antibodies to selectively detect elevated levels of specific drugs on surfaces and solids.
