Limitations
These test results should not be the sole basis for diagnosis. Test results should be always correlated with imaging and cytology.
This test does not distinguish between malignant and nonmalignant mucinous cysts.
In rare cases, some individuals can develop antibodies to mouse or other animal antibodies (often referred to as human anti-mouse antibodies [HAMA] or heterophile antibodies), which may cause interference in some immunoassays. Caution should be used in interpretation of results and the laboratory should be alerted if the result does not correlate with the clinical presentation.
