The description focuses on the physical components, miniaturization, and mechanical aspects of the analyzer, with no mention of AI or ML algorithms for data analysis or interpretation.
No
The device is an in vitro diagnostic (IVD) device used for the quantitative determination of body fluid constituents, not for treatment or diagnosis of a disease or condition in a patient.
Yes
The "Intended Use / Indications for Use" section explicitly states that the device is "indicated for in vitro diagnostic use."
No
The device description clearly outlines numerous hardware components, including a cuvette rotor, pump, and integrated pipettor/dilutor, in addition to the controlling personal computer. This indicates it is a physical device with integrated software, not a software-only medical device.
Yes, this device is an IVD (In Vitro Diagnostic).
The "Intended Use / Indications for Use" section explicitly states: "The AG" Chemistry Analyzer is indicated for in vitro diagnostic use for the quantitative determination of body fluid constituents using automated spectrophotometric methods."
This statement directly identifies the device's purpose as being for in vitro diagnostic use.

Device Description
The AG" Automated Chemistry Analyzer is the latest in a series of automated blood chemistry analyzers for the clinical chemistry laboratory that have become more and more compact as the miniaturization of the technology of the various components has proceeded. The AG" weighs only 37% as much as the currently marketed device, the ASCA Automated Spin Chemistry Analyzer, and has a "footprint" only about one-third as large. The AG" is controlled with a personal computer with a good color monitor, floppy disk drive, hard drive, and printer.
The cuvette rotor has a unique self-contained design. Forty cuvettes make up a single cuvette rotor. Each cuvette is made up of a sample shelf and reagent well. The design allows reactions to be completed in the rotor rather than having to be transferred upon mixing, by centrifugal force, to a separate cuvette or reading chamber. The pump uses a rack and pinion drive with a resolution of 3000 steps. The integrated pipettor/dilutor boasts an accuracy of & 1.0% at full stroke and a precision of & 0.05% CV within-run at full stroke. This provides excellent accuracy and precision over a wide range of volumes and speeds.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Landmark Scientific carried out testing to address the following issues:
- (1) electrical safety;
- (2) electromagnetic compatibility;
- (3) precision;
- (4) accuracy of results for standard samples; and
- comparison of performance of the AG" and predicate device on (5) clinical samples.
The results from these tests supported the safety and effectiveness of the AG" System and demonstrated that it is substantially equivalent to the predicate device.

A. LEGALLY MARKETED PREDICATE DEVICES
The AG" Automated Chemistry Analyzer System is substantially equivalent to its predicate device currently marketed by Landmark Scientific, the AutoMed Centrifugal Analyzer with Automated Rotor Loader (K781900 and K853453).
B. DEVICE DESCRIPTION
The AG" Automated Chemistry Analyzer is the latest in a series of automated blood chemistry analyzers for the clinical chemistry laboratory that have become more and more compact as the miniaturization of the technology of the various components has proceeded. The AG" weighs only 37% as much as the currently marketed device, the ASCA Automated Spin Chemistry Analyzer, and has a "footprint" only about one-third as large. The AG" is controlled with a personal computer with a good color monitor, floppy disk drive, hard drive, and printer.
The cuvette rotor has a unique self-contained design. Forty cuvettes make up a single cuvette rotor. Each cuvette is made up of a sample shelf and reagent well. The design allows reactions to be completed in the rotor rather than having to be transferred upon mixing, by centrifugal force, to a separate cuvette or reading chamber.

precision of & 0.05% CV within-run at full stroke. This provides excellent accuracy and precision over a wide range of volumes and speeds.
INTENDED USE C.
The AG" Chemistry Analyzer is indicated for in vitro diagnostic use for the quantitative determination of body fluid constituents using automated spectrophotometric methods.
TECHNOLOGICAL CHARACTERISTICS D.
The AG" System has the same technological characteristics as the predicate device. The AG" is simply a modification with updated hardware and cosmetic changes from the predicate device.
TESTING E.
Landmark Scientific carried out testing to address the following issues:
- (1) electrical safety;
- (2) electromagnetic compatibility;
- (3) precision;
- (4) accuracy of results for standard samples; and
- comparison of performance of the AG" and predicate device on (5) clinical samples.
The results from these tests supported the safety and effectiveness of the AG" System and demonstrated that it is substantially equivalent to the predicate device.
CONCLUSIONS F.
The AG" device has the same intended use as the predicate device. Landmark Scientific Inc. has demonstrated through its performance tests on the AG" System and its comparison of the AG" characteristics with those of the predicate device that the AG" System is substantially equivalent to the predicate device.

Dear Dr. Athey:
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 Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General requlation (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 requlatory 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 obliqation you miqht 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.
