Special Instructions
Not provided.
Limitations
The limitations of the Benztropine, Serum or Plasma test include its reliance on appropriate specimen handling and storage. Failure to separate the serum or plasma from cells within the specified time frame may lead to inaccurate results. Additionally, the use of gel-barrier tubes can affect the integrity of the specimen and lead to rejection. The assay may not detect extremely low levels of the drug; therefore, clinical correlation is necessary for interpretation of results.
