The summary describes a standard in vitro diagnostic immunoassay and does not mention any AI or ML components.
No.
This device is an in vitro diagnostic (IVD) method used to measure a biomarker (deoxypyridinoline) in urine, which helps indicate bone resorption. It is used for diagnostic purposes, not for treating, preventing, or mitigating a disease or condition.
Yes
The text explicitly states "This in vitro diagnostic method is intended to quantitatively measure deoxypyridinoline (DPD) in human urine" and "Measurements obtained by this device are used as an indicator of bone resorption," clearly indicating its use for diagnostic purposes.
No
The device is an in vitro diagnostic assay, which involves chemical reagents and laboratory equipment (specifically the Bayer Immuno 1™ system) to measure a substance in a biological sample (urine). This is a hardware-dependent process, not a software-only function.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use / Indications for Use: The very first sentence explicitly states, "This in vitro diagnostic method is intended to quantitatively measure deoxypyridinoline (DPD) in human urine..." This directly identifies it as an in vitro diagnostic method.
- Sample Type: The device analyzes human urine, which is a biological sample taken from the body for in vitro analysis.
- Purpose: The measurements are used as an "indicator of bone resorption," which is a diagnostic purpose.
- Device Description: While it describes an immunoassay format, the context of its use with human urine for diagnostic purposes confirms its IVD nature.
The entire description aligns with the definition of an In Vitro Diagnostic device, which is used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes.
N/A
Intended Use / Indications for Use
This in vitro diagnostic method is intended to quantitatively measure deoxypyridinoline (DPD) in human urine on the Bayer Immuno 1™ system. Measurements obtained by this device are used as an indicator of bone resorption. Results obtained using the Bayer Immuno 1 system Deoxypyridinoline method are generally expressed as a ratio to urine creatinine (nM DPD/mM creatinine), and should be interpreted in coniunction with all other available clinical and diagnostic results. The urine creatinine result (mmol/L) must be entered from an off-system standard laboratory analysis.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Sensitivity: Minimum Detectable Concentration
The minimum detectable concentration is 0.8 nM. This is a multisystem estimate of two times the within run standard deviation of the zero calibrator.
Imprecision
Within run and total imprecision were evaluated for the IMMUNO 1 DPD assay over a 10 day period using two IMMUNO 1 instruments (20 runs total). Three controls were assayed in duplicate for each run making a total of 40 assays.
Method Comparison
A total of 341 human urine samples were assayed by the IMMUNO 1 DPD method and the Pyrilinks® -D method. Urine samples were clarified by centrifugation prior to assay on the IMMUNO 1. The document mentions "CORRELATION DATA" but the table content is not extractable.
Recovery
Eleven urine samples with endogenous DPD levels ranging from 0 nM to 158.5 nM were spiked with 100 nM DPD and the recovered DPD was determined using the IMMUNO 1 DPD method. The recovery results ranged from 96% to 110% with an average of 101.7% ± 3.8%.

Dear Mr. Muraca
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 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 Requlations, 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 Regulation (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. Please note: this response to your premarket notification 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.

Under the Clinical Laboratory Improvement Amendments of 1988 (CLIA-88), this device may require a CLIA complexity categorization. To determine if it does, you should contact the Centers for Disease Control and Prevention (CDC) at (770) 488-7655.
This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
If you desire specific advice for your device on our labeling requlation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at (301) 594-4588. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97).
