This test was poerformed using a laboratory developed ELISA method. Values obtained with different assay methods cannot be used interchangeabley. Chromogranin A levels, regardless of value, should not be interpreted as absolute evidence of the presence or absence of disease.
This test was developed and its analytical performance characteristics have been deterrmined by Quest Diagnostics Nichols Institute San Juan Capistrano. It has not been cleared or approved by FDA. This assay has been validated pursuant to the CLIA reggulations and is used for clinical purposes. |
