The calibrators are designed for prescription use with homogeneous enzyme immunoassays on automated clinical chemistry analyzers. The Lin-Zhi Multiple Analyte Set A, B, and C Urine Drugs of Abuse Controls are intended for in vitro diagnostic use to monitor the performance of assays for the analytes currently listed in the package insert: Benzoylecgonine, Methamphelamine, Methadone, 6-acetylmorphine, Oxazepan, and Secobarbital. The controls are designed for prescription use with homogeneous enzyme immunoassays on automated clinical chemistry analyzers.
Device Description
All of the LZI Multiple Analyte Set A, B, and C Drugs of Abuse Calibrators and Controls are liquid and ready to use. These Calibrators and Controls do not have any especially unique technical characteristics. Each contains a known concentration of a specific drug analyte as a mixture. The Negative DAU Calibrator is a processed, drug-free human urine matrix in human urine with sodium azide (0.09%) as preservative. The Low. Cutoff. Intermediate, and High Calibrators, as well as the 2 levels of Controls are prepared by spiking known concentrations of drug analyte into the Negative DAU Calibrator matrix. These five calibrators and two controls are sold as individual bottles.
More Information

No
The device description and intended use clearly define the product as calibrators and controls for drug assays, which are standard laboratory reagents and do not involve AI/ML. The document explicitly states "Mentions AI, DNN, or ML: Not Found".

No.
This device is an in vitro diagnostic (IVD) product used for calibrating and monitoring assays for drugs of abuse. It does not treat or diagnose a disease in a patient.

Yes

Explanation: The "Intended Use / Indications for Use" section explicitly states that the calibrators and controls are "intended for in vitro diagnostic use." This indicates that they are used as part of a diagnostic process to measure analytes for medical purposes.

No

The device is described as liquid calibrators and controls containing known concentrations of drug analytes in a urine matrix. This is a physical substance, not software.

Yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use/Indications for Use: The document explicitly states that the calibrators and controls "are intended for in vitro diagnostic use".
  • Device Description: The device is a reagent (liquid calibrators and controls) used to calibrate and monitor the performance of assays for detecting drugs of abuse in urine, which is a biological sample.
  • Intended User/Care Setting: The device is designed for "prescription use with homogeneous enzyme immunoassays on automated clinical chemistry analyzers," which are typical settings for in vitro diagnostic testing.

The entire context of the document describes a product used in a laboratory setting to perform diagnostic tests on patient samples (urine).

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Performance Characteristics Summary:
Multiple Analyte Sets A,B, and C Drugs of Abuse Calibrators and Controls Stability:
Based on the largest % change for any individual concentration or % change in Total Separation (versus Day 0 measurements) at Cold (2-8 ℃), Room Temperature, and Accelerated (30 ℃) Temperature sudies, the LZ1 Multiple Analyte Set A. B. and C Drugs of Abuse Calibrators and Controls did not vary greater than +/-10%. In Set A. the only analyte for which this differed was the 6- acetylmorphine (6AM) Calibrator and Control. In Set B and C. the only analyte for which this differed was the Benzodiazeoine (Oxazepam) Calibrator and Control. All calibrators and controls held steady when stored at 2 ℃ to 8 ℃ (refrigerated) up to Day 366 real time. Based on these data we have capped our predicted shelf-life to the current cold temperature real-time study for the LZI Multiple Analyte Sets A. B. and C Drugs of Abuse Calibrators and Controls to at least 12 months.

Traceability and Value Assignment:
The starting materials for the calibrators and controls were commercially available standard stock solutions in methanol. The standard solution was found to be 99% in purity, analvzed by GC/MS, Secondary stock solutions were prepared using negative urine calibrator matrix and the concentrations were verified gravimetrically using balances calibrated with NIST traceable weights. The secondary stock solutions were then spiked into the negative urine calibrator matrix to the desired concentration and verified by GC/MS to be within ± 10% of the uarget concentration.

Summary:

The information provided in this pre-market notification demonstrates that the LZJ Multiple Analyte Sets A. B. and C Drugs of Abuse Calibrators and Controls are substantially equivalent to the legally marketed predicate device for its general intended use. Substantial equivalence was demonstrated through comparison of intended use and physical properties to the commercially available predicate device as confirmed by gas chromatography/mass spectrometry (GC/MS), an independent analytical method. The information supplied in this pre-market notification provides reasonable assurance that the LZI Multiple Analyte Sets A, B, and C Drugs of Abuse Calibrators and Controls are safe and cflective for its stated intended use.

Dear Dr. Lin:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment dute of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food. Drug. and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract fiability warranties. We remind you, however, that device labeling must be truthful and not misleading,

If your device is classified (see above) into either class II (Special Controls) or class III (PMA). it may be subject to additional controls.
