No
The summary describes a standard enzyme immunoassay for quantitative analysis and does not mention any AI or ML components.
No
This device is an immunoassay intended for quantitative analysis of salicylic acid in human serum or plasma for diagnostic and monitoring purposes, not for direct therapeutic intervention.
Yes
The "Intended Use / Indications for Use" section explicitly states that "Measurements obtained from this device are used in the diagnosis and treatment of salicylic acid overdose or in monitoring levels of salicylic acid to ensure appropriate therapy." This directly indicates a diagnostic purpose.
No
The device is described as a "homogenous enzyme immunoassay" and "homogenous enzyme assay," which are laboratory-based chemical tests requiring reagents and potentially specialized equipment, indicating it is not solely software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states it's for "quantitative analysis of salicylic acid in human serum or plasma." This involves testing biological samples in vitro (outside the body).
- Purpose: The measurements are used "in the diagnosis and treatment of salicylic acid overdose or in monitoring levels of salicylic acid to ensure appropriate therapy." This directly relates to providing information for medical diagnosis and treatment decisions.
- Device Description: The description confirms it's a "homogenous enzyme assay intended for use in quantitative analysis of Salicylic Acid in human serum or plasma," reinforcing the in vitro nature of the testing.
These points clearly align with the definition of an In Vitro Diagnostic device, which is used to examine specimens taken from the human body to provide information for diagnosis, monitoring, or treatment.

Summary of Performance Studies
Specificy: Compounds, whose chemical structure would suggest possible crossreactivity or other therapeutics concurrently used, when tested on the Emit® tox ™ Salicylic Acid Assay, did not interfere at the levels tested.
Comparative Analysis: The Emit® tox™ Salicylic Acid Assay and calibrators showed excellent correlation to the predicate method. The comparative analysis to the predicate method resulted in a correlation of 0.993 with a slope value of 0.941.
Precision: A Precision study was performed and the Emit® tox™ Salicylic Acid Assay demonstrated acceptable within-run precision with coefficients of variation (%CV) ranging from 2.9% to 4.5% and acceptable total precision with coefficients of variation (%CV) ranging from 3.9% to 5.8%.
Spike Recovery: A spike recovery study was performed using 7 levels of spiked salicylic acid. The recovery ranged from 91.8% to 104.7%.
Sensitivity: The sensitivity level of the Emit® tox™ Salicylic Acid Assay is $5 mg/dL Salicylic Acid. This level represents the lowest measurable concentration of salicylic acid that can be distinguished from 0 mg/dL with a confidence of 95%.
Endogenous Interference: Average recovery compared to control samples was studied separately to assess endogenous interference due to bilirubin, hemoglobin and triglycerides in the Emit® tox™ Salicylic Acid Assay. Average recoveries were 98.7, 99.4 and 102 percent for bilirubin, hemoglobin and triglycerides, respectively. There was no effect on the accuracy of the results.
High Sample Dilution: High sample dilution was evaluated by diluting a high spike sample four different ways. Separate 1:2 and 1:3 dilutions with Emit® tox™ Salicylic Acid Calibrator 0, and 1:3 dilutions with water for each spike sample were assayed. The recovery values ranged from 104 to 107 percent. There was no effect on the accuracy of the results.
Anticoagulants: The performance of the anticoagulants KJEDTA, sodium citrate, sodium heparin, and potassium oxalate/sodium fluoride, as compared to serum was tested on Emit® tox™ Salicylic Acid Assay. Average recovery, compared to serum control ranged from 98.6 to 106.3 percent.
