This drug screening test uses a machine to check for the presence of one or more specific drugs. The sample tested can be blood, hair, urine or saliva. The type of sample used depends on the specific circumstances. There are advantages and disadvantages associated with each sample type. The period of time during which a drug will test positive also depends on the type of sample used, how much of the drug a person has taken and how fast someone's body breaks down the drug. For example:
Testing for drugs can be done for several different reasons, such as:
A positive test means that a drug was found above the established level. A test is negative if the test result is "not detected" or "none detected." This means that the drug was not found above the established level.
If a blood sample is required, the costs in this care path do not include the charge to draw blood from a vein (venipuncture). There will only be one charge to draw blood, even if multiple tests are being performed on the samples that are taken.
