No
The device description details a chemical assay based on enzymatic reactions and selective detergents, with no mention of computational analysis, algorithms, or learning processes. The performance studies focus on standard analytical metrics like correlation, precision, and linearity, not AI/ML performance metrics.
No
The device is described as an "in vitro diagnostic assay" used for the quantitative determination of high-density lipoprotein cholesterol levels to aid in diagnosis and treatment, not to provide therapy itself.
Yes
The "Intended Use / Indications for Use" section states, "Low Direct HDL measurements are used in the diagnosis and treatment of coronary artery disease." This indicates that the device provides information used for diagnosis.
No
The device description clearly indicates it is an in vitro diagnostic assay involving chemical reagents and reactions to measure HDL levels, which is a hardware-based process.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The "Intended Use / Indications for Use" section explicitly states that the assay is used for the quantitation of HDL cholesterol levels in human serum or plasma, and that these measurements are used in the diagnosis and treatment of coronary artery disease. This clearly indicates a diagnostic purpose.
- Device Description: The "Device Description" further clarifies that it is an "in vitro diagnostic assay" for the quantitative determination of HDL cholesterol in serum or plasma. The description of the chemical process involved in analyzing the sample also aligns with the nature of an in vitro diagnostic test.
- Predicate Device: The mention of a "Predicate Device" (K963213 Boehringer Mannheim® Direct HDL-Cholesterol assay) which is also an IVD, strongly suggests that this device falls into the same category.
The information provided clearly defines the device as a test performed on biological samples (serum or plasma) outside of the body (in vitro) to provide information for diagnostic purposes.

Device Description
Direct HDL is an in vitro diagnostic assay for the quantitative determination of high-density lipoprotein cholesterol in serum or plasma. The Direct HDL assay is a two reagent format and depends on the properties of a unique detergent. This detergent solubilizes only the HDL lipoprotein particles, thus releasing the HDL cholesterol to react with cholesterol esterase and cholesterol oxidase, in the presence of chromogens to produce color. In addition to selectively disrupting the HDL lipoprotein particles, this unique detergent also inhibits the reaction of the cholesterol enzymes with LDL, VLDL, and chylomicron lipoproteins by adsorbing to their surfaces. A polyanion is contained in the first reagent to assist with complexing LDL, VLDL, and chylomicron lipoproteins, further enhancing the selectivity of the detergent and enzymes for HDL cholesterol.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Comparative performance studies were conducted using the AEROSET™ System. The Direct HDL assay method comparison yielded acceptable correlation with the Boehringer Mannheim Direct HDL-Cholesterol assay on the Hitachi 717 Analyzer. The correlation coefficient = 0.9883, slope =1.041, and Y-intercept =0.118 mg/dL. Precision studies were conducted using the Direct HDL assay. Within-run, between-run, and between-day studies were performed using two levels of control material. The total %CV for Level 1/Panel 109 is 5.3% and Level 2/Panel 110 is 3.3%. The Direct HDL assay is linear up to 309.6 mg/dL. The limit of quantititation (sensitivity) of the Direct HDL assay is 1.2 mg/dL. These data demonstrate that the performance of the Direct HDL assay is substantially equivalent to the performance of the Boehringer Mannheim Direct HDL-Cholesterol assay on the Hitachi 717 Analyzer.
Key Metrics (Sensitivity, Specificity, PPV, NPV, etc.)
The correlation coefficient = 0.9883, slope =1.041, and Y-intercept =0.118 mg/dL. The total %CV for Level 1/Panel 109 is 5.3% and Level 2/Panel 110 is 3.3%. The Direct HDL assay is linear up to 309.6 mg/dL. The limit of quantititation (sensitivity) of the Direct HDL assay is 1.2 mg/dL.

Dear Mr. Littlefield:
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, labelinq, 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 Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Druq Administration (FDA) will verify such assumptions. Failure to comply with the GMP requlation 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 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.
