NO - these tests are conducted with GC/MS confirmation. While some medications can theoretically cause false positive results on the screening immunoassay, the GC/MS confirmation test eliminates this problem. Essentially, the GC/MS is a "chemical fingerprint" of the particular drug - which is unique and specific to the substance.
