## Indications for Use

The VALIDATE TDM Calibration Verification Test Set is used by trained laboratory professions for the quantitative determination of linearity, calibration verification and verification of reportable range in automated, semi-automated, and manual clinical chemistry systems for the following analytes: Acetaminophen, amikacin, carbamazepine, digoxin, gentamicin, lidocaine, phenobarbital, phenytoin, primidone, procainamide, quinidine, salicylate, theophylline, tobramycin, valproic acid, and vancomycin

## Device Story

VALIDATE TDM Calibration Verification Test Set consists of purified chemicals in human serum matrix; provided in six levels including zero; 5 mL per bottle. Used by laboratory professionals in clinical chemistry systems to verify instrument performance, linearity, and reportable ranges for therapeutic drug monitoring. Device serves as a calibration verification tool; does not perform clinical diagnosis directly. Benefits include ensuring accuracy and reliability of clinical chemistry system results for therapeutic drug monitoring.

## Clinical Evidence

No clinical data provided. Bench testing only; traceability established via NIST Standard Reference Materials (SRM 900 and 1599) or primary analytical standards.

## Technological Characteristics

Purified chemicals in human serum matrix; liquid, ready-to-use form. 6 levels per set, 5 mL per bottle. Storage at 2-8°C. No electronic components, software, or energy sources.

## Regulatory Identification

A clinical toxicology calibrator is a device intended for medical purposes for use in a test system to establish points of reference that are used in the determination of values in the measurement of substances in human specimens. A clinical toxicology calibrator can be a mixture of drugs or a specific material for a particular drug (e.g., ethanol, lidocaine, etc.). (See also § 862.2 in this part.)

## Special Controls

*Classification.* Class II (special controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 862.9.

## Predicate Devices

- TDM I CAL-VER ([K913309](/device/K913309.md))
