Insulin, I.V. Fluid
Also known as: INS IVF
Use
This test is intended to provide an estimate of the insulin concentration in I.V. fluid samples for medical purposes. It provides valuable information for medical professionals to assess the amount of insulin present in IV solutions. However, accuracy of the result may be decreased in the presence of high insulin concentrations and/or other substances present in the I.V. fluid.
Special Instructions
The assay used has been cleared by the FDA for use on serum samples, but ARUP has validated it for use on I.V. fluid specimens. Please convert insulin results from µIU/mL to IU/mL if needed by dividing by 1,000,000. If performing the test in New York, submit a Non-Permitted Laboratory Request Form to the NYDOH prior to collection of specimen as the test is not approved by New York state.
Limitations
The test's accuracy may be compromised at high insulin concentrations and in the presence of other substances in the I.V. fluid. Additionally, the test has not been cleared or approved by the US Food and Drug Administration for this specific application but has been developed and validated by ARUP Laboratories under CLIA certification. Results interpretation must consider these limitations.
