Not Found
No
The device description details a turbidimetric assay based on antibody-antigen reactions and absorbance measurements, which is a standard laboratory technique and does not mention or imply the use of AI or ML. The "Mentions AI, DNN, or ML" field is explicitly marked as "Not Found".
No.
This device is an in vitro diagnostic assay used to quantify apolipoprotein A-I, which can aid in assessing the risk of coronary artery disease, but it does not treat or prevent a disease.
Yes
The 'Intended Use / Indications for Use' section explicitly states, "For in vitro Diagnostic use." and "It can be used as an aid for assessing the risk of coronary artery disease," which indicates its role in disease diagnosis or risk assessment.
No
The device description clearly indicates a method based on a chemical reaction and turbidimetric measurement, which requires physical reagents and an instrument (spectrophotometer or similar) to perform the assay. This is an in vitro diagnostic device with hardware components, not a software-only device.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Explicit Statement: The "Intended Use / Indications for Use" section clearly states: "For in vitro Diagnostic use." This is the most direct indicator.
- Nature of the Assay: The assay measures a substance (apolipoprotein A-I) in a biological sample (serum) to provide information for assessing a health condition (risk of coronary artery disease). This is the fundamental purpose of an in vitro diagnostic device.
- Components: The description includes components like calibrators and controls, which are standard for IVD assays to ensure accurate and reliable results.
- Predicate Device: The mention of a predicate device (K993345; K-Assay Apo AI Assay) which is also an Apo AI assay, further supports its classification as an IVD, as predicate devices are used for comparison in regulatory submissions for new IVDs.

Principle
| Diazyme Apolipoprotein A-I Assay | K-Assay Apo AI Assay | Equivalency |
|---|---|---|
| This method is based on the reaction of a sam- | ||
| ple containing human Apo A-I and specific | ||
| antiserum to form an insoluble complex which | ||
| can be measured turbidimetrically at 340nm. | ||
| By constructing a standard curve from the ab- | ||
| sorbance of standards the concentration of Apo | ||
| A-1 can be determined. | This method quantifies Apolipoprotein AI | |
| based on immunoturbidimetric assay. The re- | ||
| agent uses a goat polyclonal antibody specific | ||
| for human Apolipoprotein AI. The antibody | ||
| binds to the Apo AI in the serum forming | ||
| light scattering immune complexes, which | ||
| increase the turbidity of the sample. Since the | ||
| turbidity is proportional to the amount of Apo | ||
| AI in the sample, the Apolipoprotein AI con- | ||
| centration can be determined by measuring | ||
| this increase in turbidity. The increase in tur- | ||
| bidity is measured at 800 nm. Apolipoprotein | ||
| AI in the sample is quantitatively determined. | Similar |

Dear Mr. Yur.
Re:
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 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) 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.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in Title 21, Code of Federal Regulations (CFR), Parts 800 to 895. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Parts 801 and 809); and good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820).
