yes it can produce false positive results. this occurs with tests that use antibodies that screen for amphetamines. sudafed contains pseudoephedrine that is similar in structure to amphetamines and therefore causes cross-reactivity with the antibodies directed against amphetamines.
if a test is being done in a legal manner; e.g. a workplace drug screen, the initial immunoassay needs to be followed up with a more precise assay - usually GC-MS. This assay will be able to differentiate between sudafed and amphetamines
