No
The summary describes a standard immunoassay system for measuring a specific analyte in urine. There is no mention of AI, ML, or any computational methods that would suggest their use. The performance studies focus on analytical comparisons and standard assay validation metrics.
No
The device is an in-vitro diagnostic system used to measure a biomarker (NTx) in urine, which helps assess bone resorption. It is for diagnostic purposes, not for treating a disease or condition.
Yes
The device is intended for the quantitative measurement of cross-linked N-telopeptides of type I collagen (NTx) in human urine as an indicator of human bone resorption. This measurement provides information for diagnostic or monitoring purposes related to a medical condition (bone resorption).
No
The device description clearly states it is a system comprised of reagent packs, calibrators, controls, and instrumentation, indicating it is a hardware-based in-vitro diagnostic device, not software-only.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The "Intended Use / Indications for Use" section explicitly states "For in-vitro quantitative measurement..." and "For in-vitro use in the calibration..." and "For in-vitro use in the monitoring...". The term "in-vitro" is a key indicator of an IVD, meaning it's used to examine specimens from the human body outside of the body.
- Device Description: The description details a system that uses "human body fluids, commonly serum, plasma and urine" and "Coated microwells are used as the solid phase separation system." This aligns with the typical components and processes of an IVD.
- Predicate Device: The mention of a "Predicate Device(s)" with a K number (K980518; Osteomark NTx Test) strongly suggests that this device is being compared to a previously cleared IVD, which is a common regulatory pathway for new IVDs.
- Reference Device(s): The reference to other VITROS Immunodiagnostic Systems (K962919 and K984310) further reinforces that this device is part of a family of IVD products.
All of these points clearly indicate that the Vitros NTx Reagent Pack, Calibrators, and Controls, when used with the VITROS Immunodiagnostic System, are intended for in-vitro diagnostic use.
N/A
Intended Use / Indications for Use
Vitros NTx Reagent Pack - For in-vitro quantitative measurement of cross linked N-telopeptides of type I collagen (NTx) in human urine as an indicator of human bone resorption. A single NTx value cannot provide the rate of bone resorption as reported results do not contain a measure of time. Use of this test has not been established in primary hyperparathyroidism or hyperthyroidism.
Vitros NTx Calibrators - For in-vitro use in the calibration of the VITROS Immunodiagnostic System for the quantitative measurement of NTx in human urine.
Vitros NTx Controls - For in-vitro use in the monitoring of the performance of the VITROS Immunodiagnostic System when used for the quantitative measurement of NTx in human urine.

Device Description
The VITROS Immunodiagnostic System uses luminescence as the signal in the quantitative and semi-quantitative determination of selected analytes in human body fluids, commonly serum, plasma and urine. Coated microwells are used as the solid phase separation system.
The system is comprised of three main elements:
-
- The VITROS Immunodiagnostic Products (in this case VITROS Immunodiagnostic Products NTx Reagent Pack, VITROS Immunodiagnostic Products NTx Calibrators, which are combined by the VITROS Immunodiagnostic System to perform the VITROS NTx assay).
-
- The VITROS Immunodiagnostic System - instrumentation, which provides automated use of the immunoassay kits. The VITROS Immunodiagnostic System was cleared for market by a separate 510(k) pre-market notification (K962919).
-
- Common reagents used by the VITROS System in each assay. The VITROS Immunodiagnostic Products Signal Reagent and VITROS Immunodiagnostic Products Universal Wash Reagent were cleared as part of the VITROS Immunodiagnostic Products Total T3 510(k) pre-market notification (K984310).
The VITROS System and common reagents are dedicated specifically only for use with the VITROS Immunodiagnostic Products range of immunoassay products.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Comparison to Predicate Device: The VITROS Immunodiagnostic Products NTx assay is substantially equivalent to Osteomark NTx test (predicate device), which was approved by FDA (K980518) for IVD use.
The relationship between the VITROS NTx assay and the predicate device, determined by Deming's Regression, is: VITROS NTx assay = 0.957 x Osteomark NTx test + 6.5 (nM BCE/mM creatinine).
Comparisons of the VITROS NTx assay and the predicate device were performed with samples from a variety of clinical categories.
In addition to the studies mentioned above, tests were performed to obtain analytical sensitivity, specificity, precision, dilution and expected values. Refer to the VITROS NTx assay package insert for VITROS NTx assay results.
Conclusion: The data presented in the pre-market notification demonstrate that the VITROS NTx assay performs substantially equivalent to the predicate device, for which there is FDA clearance. Equivalence was demonstrated using currently commercially available reagents along with patient specimens covering a variety of clinical categories. The data presented in the premarket notification provide a reasonable assurance that the VITROS NTx assay is safe and effective for the stated intended use.

Dear Ms. Zavertnik:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we 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 date 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). 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.
If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Requlation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. this response to your premarket notification Please note: submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
