Methotrexate therapeutic drug monitoring IVD, control

This category includes control materials used to verify the accuracy and reliability of laboratory tests that measure methotrexate levels in patient samples. These controls are essential for ensuring that therapeutic drug monitoring assays perform correctly, helping clinicians adjust dosages for cancer and autoimmune disease treatments based on precise drug concentration readings.

As in vitro diagnostic (IVD) controls, these materials are regulated to support the performance verification of associated methotrexate assays. They are not diagnostic tools themselves but are critical for quality assurance in testing laboratories, typically supplied as stabilized, matrix-based preparations with known analyte concentrations to validate test runs.
