A signature is the comparative file that the ValiMed System uses to validate the medication sample.
The signature represents a specific medication, *concentration and *diluent combination.
For example, Vancomycin 10 mg/mL in D5W and 10 mg/mL in normal saline would be two separate signatures. Vancomycin 5 mg/mL D5W and Vancomycin 10 mg D5W would be two signatures.
The machine also has the ability to measure concentrations. A solution under test can be validated by comparing it to a standard concentration on file in the data library.
