If someone receives a positive result through their screening test, the next common step is to order a more detailed test. The second, more detailed test may be more expensive and may take longer to produce a result, but it is more accurate. Urine tests are also often tampered with or attempted to be beat by adding chemicals to the urine, diluting it with water, or ingesting substances that are known to interfere with the test. Many drug and alcohol facilities will require testing to be monitored closely in order to avoid tampering.
