This test was developed and its performance characteristics determined by Beaumont Health. It has not been cleared or approved by the FDA. The Laboratory is regulated under CLIA as qualified to perform high-complexity testing. This test is used for clinical purposes and should not be regarded as investigational or for research.
Sodium nitroprusside releases cyanide ion which is converted in the body to thiocyanate. High thiocyanate serum concentrations may result from acute exposure to cyanide or chronic exposure to sodium nitroprusside. Thiocyanate toxicity may occur in patients with renal failure and long-term continuous IV infusions.
This assay is used to monitor the therapeutic drug level and evaluate the toxicity of thiocyanate (nitroprusside). Thiocyanate (nitroprusside) is a rapid-acting hypotensive agent used to treat hypertensive crisis and to produce controlled hypotension during surgery.
