The device description and performance studies focus on enzymatic reactions and absorbance measurements, which are standard chemistry analysis techniques, not AI/ML. There is no mention of AI, ML, or related concepts.
No.
The device is intended for the quantitative determination of HDL cholesterol in serum, which is used for diagnostic purposes and risk assessment, not for direct treatment or therapy.
Yes
The device is described as being used in the "diagnosis and treatment of lipid disorders, atherosclerosis and various liver and renal diseases," which is a diagnostic purpose.
No
The device description clearly states it is a "system" including a "Reagent Kit," "Calibrator," and a "Random Access Chemistry System," which are all hardware components.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states the device is for the "quantitative determination of high density in serum." This involves testing a biological sample (serum) in vitro (outside the body).
- Purpose: The results are used "in the diagnosis and treatment of lipid disorders, atherosclerosis and various liver and renal diseases, and as a tool to assess the risk of developing and managing the progression of cardiovascular disease." This clearly indicates a medical purpose related to diagnosis and treatment.
- Device Description: The description details how the device analyzes a biological sample (serum) using chemical reactions to measure a specific analyte (HDL-cholesterol). This is characteristic of an IVD.
- Care Setting: It is intended for use by "trained personnel in a professional setting," which is typical for IVD devices used in clinical laboratories.
The information provided 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.

Device Description
The ATAC-PAK Direct HDL Cholesterol Reagent determines HDL-cholesterol through the enzymatic action of cholesterol esterase, cholesterol oxidase and peroxidase after the selective removal non-HDL sources of cholesterol. The resulting increase in absorbance at 578 nm is proportional to the HDL cholesterol concentration in the sample.

Summary of Performance Studies
The effectiveness of ATAC-PAK Direct HDL Cholesterol Reagent Kit and the ATAC HDL-C Calibrator used on the ATAC 8000 Random Access Chemistry System are shown by the following studies.
The recovery of HDL cholesterol using the ATAC-PAK Direct HDL Cholesterol Reagent is linear from 1 mg/dL to 150 mg/dL as shown by the recovery of linearity standards which span the claimed linear range. Regression statistics, comparing standard recoveries, which range from 0.6 to 155.5 mg/dL, to standard values are shown below.
(ATAC Recoveries) = 1.8 mg/dL + 0.981 x (Standard Value), r2 = 0.999. di = 8 sy.x = 1.77 mg/dL.
Precision, demonstrated by replicate assay of commercially available control sera, is shown below.
| Specimen | n | mean | within-run SD | total SD |
|---|---|---|---|---|
| Serum control 1 | 40 | 29.8 mg/dL | 1.76 mg/dL | 1.71 mg/dL |
| Serum control 2 | 40 | 45.1 mg/dL | 2.26 mg/dL | 2.23 mg/dL |
One hundred and thirty eight serum specimens, collected from adult patients, were assayed for HDL cholesterol using the ATAC 8000 Random Access Chemistry System and another accepted clinical method. Results ranging from 17 to 99 mg/dL were compared by least squares linear regression and the following statistics were obtained.
y = 3.2 mg/dL + 0.938x r = 0.969 y = ATAC 8000 results x = accepted clinical method
The detection limit claim of 1 mq/dL is documented through the repetitive assay of a diluted HDL-C control. The observed detection limit, calculated as two standard deviations of a 22 replicate within run precision study, is 0.66 mg/dL and is below the claimed limit.
The 14 day on board reagent stability and calibration stability claims are documented through the assay of serum controls over the claimed periods. In all cases, the ranges of HDL-cholesterol recoveries over the test than 8 mg/dL.

SUMMARY OF 510(K) SAFETY AND EFFECTIVENESS INFORMATION
This summary of 510(k) safety and effectiveness information is being submitted in accordance with the requirements of SMDA 1990 and 21 CFR 807.92.
The ATAC-PAK Direct HDL Cholesterol Reagent Kit, the ATAC HDL-C Calibrator and the ATAC 8000 Random Access Chemistry System are used as a system for the quantitative analysis of high density lipoprotein cholesterol (HDL-C) in serum. HDL-cholesterol results are used in the diagnosis and treatment of lipid disorders and various liver and renal diseases, and as a tool to assess the risk of developing and managing the progression of cardiovascular disease.
The ATAC-PAK Direct HDL Cholesterol Reagent determines HDL-cholesterol through the enzymatic action of cholesterol esterase, cholesterol oxidase and peroxidase after the selective removal non-HDL sources of cholesterol. The resulting increase in absorbance at 578 nm is proportional to the HDL cholesterol concentration in the sample.
The ATAC-PAK Direct HDL Cholesterol Reagent Kit and ATAC HDL-C Calibrator are substantially equivalent to the Homogeneous Auto-Direct HDL-C Plus Reagent Kit, which is currently marketed by DMA, Inc.
The effectiveness of ATAC-PAK Direct HDL Cholesterol Reagent Kit and the ATAC HDL-C Calibrator used on the ATAC 8000 Random Access Chemistry System are shown by the following studies.

Dear Mr. Stocking:
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 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.
