The device description and performance studies focus on chemical calibrators and their use in verifying the linearity of therapeutic drug monitoring methods, with no mention of AI or ML.
No.
The device is a linearity verifier used to calibrate and verify the performance of methods and instruments that measure therapeutic drugs, not to treat patients directly.
No
The device is a linearity verifier used to confirm the proper calibration and linear operating range of methods for determining the concentration of therapeutic drugs, not to diagnose a condition in a patient. It is a quality control/calibration tool for other diagnostic devices.
No
The device description clearly states it is a "five level, multiconstituent set of calibrators made in human serum," indicating it is a physical product (reagents/calibrators) and not software.
Based on the provided information, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states that the device is used to "verify the calibration, linear operating range and reportable range (linearity) of methods used to determine the concentration of therapeutic drugs." This is a clear diagnostic purpose, as it relates to the accuracy and reliability of tests performed on patient samples.
- Device Description: The description further clarifies that it's a "medical device intended for use with automated and manual methods monitoring selected therapeutic drugs (TDM)." TDM is a diagnostic process. The device is used to "confirm the proper calibration, linear operating range and reportable range (linearity) of TDM methods."
- Function: The device functions as a set of calibrators/verifiers used to assess the performance of diagnostic tests (TDM methods). This is a core function of many IVD devices.
The fact that it's used with diagnostic methods to ensure their accuracy firmly places it within the realm of In Vitro Diagnostics.

Intended Use / Indications for Use
AC/AD Linearity Verifiers are intended to be used to verify the calibration, linear operating range and reportable range (linearity) of methods used to determine the concentration of therapeutic drugs.
AC/AD Linearity Verifiers should be used any time it is necessary to confirm the proper calibration and linear operating range of TDM methods and instruments. Quality control/verification requirements should be determined in conformance with local, state and/or Federal regulations or accreditation requirements

Device Description
medical device intended for use with automated and manual methods monitoring selected therapeutic drugs (TDM). AC/AD Linearity Verifiers is a five level, multiconstituent set of calibrators made in human serum and used to confirm the proper calibration, linear operating range and reportable range (linearity) of TDM methods. The "AC/AD" designation derives from AntiConvulsant, antiAnxiety and other Qrugs. AC/AD Linearity Verifiers contains concentrations of analytes extending over a wide analytical range. Level 1 is a zero level 5 has a concentration near the upper limit of instruments. Levels 1, 2, 3, and 4 are related by linear dilution. When assayed like patient samples, the verifiers assist in determination of calibration and linear operating range (linearity) of methods for the analytes included.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The performance of AC/AD Verifiers has been tested on three commonly used automated therapeutic drug monitoring systems (Abbott TDx Assay System, Dade-Behring (formerly Syva) EMIT system, and Roche-Boehringer CEDIA reagents), by two colorimetric methods (GED reagents for acetaminophen and Sigma Diagnostic reagents for salicylate) and by HPLC (for nordiazepam) to validate their use. Most methods tested demonstrated the desired functionality of the product. Carbamazepine by fluorescence polarization immunoassay demonstrated a significant miscallbration believed to be real. GED reagents for acetaminophen gave results which might indicate incompatibility with AC/AD vertfiers. However, the GED reagents gave a level-correlated, proportional colorimetric response with the verifiers, and it was not possible to rule out a miscalibration. EMIT reagents for ethosuximide reacted with an interferent in the AC/AD base matrix, and this product is not useful with the EMIT ethosuximide reagents.
