Answer 21

Nucleic acid amplification test, including the PCR has both excellent specificity and sensitivity and yields rapid results, but is very expensive. The EIA is an expensive and rapid, but poor sensitivity and specificity culture has excellent sensitivity and specificity requires a secondary test for toxins. It requires 3 to 4 days to complete.
