The description details a chemical reaction-based assay and a chemistry system, with no mention of AI or ML in the device description, intended use, or performance studies.
No
The device is intended for the quantitative determination of LDL-cholesterol, which is used in the diagnosis and assessment of risk, not for direct treatment or therapy. It's a diagnostic tool.
Yes
The "Intended Use / Indications for Use" section explicitly states that "LDL-cholesterol measurements are used in the diagnosis and treatment of lipid disorders... and for the assessment of the risk of developing cardiovascular disease." This directly indicates a diagnostic purpose.
No
The device description clearly outlines a reagent kit and a chemistry system, which are hardware components used for performing a chemical reaction to determine LDL-cholesterol. This is not a software-only device.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states the quantitative determination of LDL-cholesterol in serum and plasma, which are biological specimens taken from the human body. It also states that these measurements are used in the diagnosis and treatment of various diseases and for risk assessment of cardiovascular disease. This aligns directly with the definition of an IVD, which is used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes.
- Device Description: The description details a chemical reaction that occurs with the sample (serum or plasma) to produce a measurable result (color proportional to LDL-cholesterol). This is a typical characteristic of an in vitro diagnostic assay.
- Specimen Type: The device uses serum and plasma, which are human biological specimens.
- Performance Studies: The document describes performance studies conducted on human serum and plasma specimens (method comparison, accuracy, precision, linearity, detection limit, stability). These studies are necessary to demonstrate the performance of an IVD.
- Predicate Device: The mention of a predicate device (K984598; N-geneous LDL Cholesterol reagent) which is also an LDL Cholesterol reagent, strongly suggests that this device is also intended to be an IVD, as predicate devices are used in the regulatory submission process for new IVDs.
Therefore, based on the provided information, the ATAC Direct LDL Reagent Kit, the ATAC Direct LDL Calibrator, and the ATAC 8000 Random Access Chemistry System are intended to be used as an In Vitro Diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The recovery of LDL-cholesterol using the ATAC Direct LDL Reagent is linear from 5 to 700 mg/dL as shown by the I ne recovery of LDL-notestere used insable range. Linear regression statistics, with the regression line forced through the origin, compare standard recoveries to standard factors.
(ATAC Recoveries) = 0 mg/dL + 1.023 x (Standard Factors), n = 35
Precision is demonstrated by the replicate assay of commercially available control serum and a serum pool. Precision statistics, calculated analogous to the method described in NCCLS Guideline EP3-T, are shown below.
Sample: Serum 1, n: 60, mean: 93, Within Run 1SD: 1.4, %CV: 1.5%, Total 1SD: 2.7, %CV: 2.9%
Sample: Serum 2, n: 60, mean: 184, Within Run 1SD: 3.3, %CV: 1.8%, Total 1SD: 4.9, %CV: 2.7%
Sample: Serum 3, n: 59, mean: 555, Within Run 1SD: 11.9, %CV: 2.2%, Total 1SD: 19.2, %CV: 3.5%
Mixed serum and plasma specimens, collected from adult patients, were assayed for LDL cholesterol using the ATAC 8000 Random Access Chemistry System and another commercially available method. Results were compared by least squares linear regression and the following statistics were obtained.
Serum/Plasma Comparison ATAC 8000 = - 1.7 mg/dL + 1.078 x Competitive Reagent range = 19 - 265 mg/dL r = 0.996 n = 159
To verify accuracy, 42 serum and plasma specimens, collected from 22 adults were assayed for LDL cholesterol using the ATAC 8000 Random Access Chemistry System and the beta-quantification reference method. Results were compared by least squares linear regression and the following statistics were obtained.
Serum/Plasma Comparison ATAC 8000 = - 4.2 mg/dL + 1.035 x reference method r = 0.986 n = 42 range = 59 - 178 mg/dL
The detection limit claim of 5 mg/dL is documented through the repetitive assay of a diluted serum pool. The observed detection limit, calculated as two standard deviations of a 30 replicate within run precision study, is 0.73 mg/dL and is below the claimed limit.
The 14 day on board reagent stability and 14 day calibration stability claims are documented through the assay of serum controls over the claimed periods. In all cases, the total imprecision of LDL-cholesterol recoveries over the test periods are less than 3%.
