Test
Limitations:
This test is not approved by the FDA for this sample type. Performance
characteristics and reference range have not been verified. A
published study using Roche Diagnostics cobas 8000 analyzers has
demonstrated that analysis of sodium in cerebrospinal fluid, drain
fluids, pancreatic fluid, pericardial fluid, peritoneal/ascites fluid,
pleural fluid, and vitreous fluid shows no evidence of systematic
matrix interference. Results should be interpreted in conjunction
with clinical findings.
