to from top to bottom but not in fluid communication in addition to these embodiments of test strips many other embodiments can be made it is also useful to provide test elements indicating the presence of adulteration contaminants for example an adulteration element can be included indicating the specific gravity of the urine sample so that adulterants that would change the specific gravity of the urine will be detected it is a common technique among those who would seek to defeat the results of an assay for drugs of abuse to add glutaraldehyde and other chemicals and many other contaminants to a urine sample further it is useful to include a test element for the physical parameter of temperature if the sample provided is not of a normal temperature expected it may provide an indication that the sample was carried to the test site and does not originate with the test subject many adulterants can be added to urine to defeat the purpose of drug screening and as many test elements as thought desirable can be incorporated into the device these adulterants and corresponding test elements are known in the art when a test strip includes an adulteration control zone the adulteration control zone can be placed before or after the results determination zone when a control zone is present in the results determination zone on such a test strip then the adulteration control zone is preferably before the control zone but that need not be the case in the embodiment of the present.
