The device description and performance studies describe a standard in vitro diagnostic assay based on antibody agglutination and light scattering, with no mention of AI or ML.
No
This device is an in vitro diagnostic test used for quantitative determination of Lipoprotein(a) in human serum or plasma to aid in diagnosis and identify risk, not for direct therapeutic treatment.
Yes
The 'Intended Use / Indications for Use' section explicitly states that the N Latex Lp(a) Reagent is an "in vitro diagnostic test" and "aids in the diagnosis of disorders of lipid (fat) metabolism and helps to identify persons at risk from cardiovascular disease".
No
The device description clearly states it is a reagent (polystyrene latex particles coated with antibodies) used in an in vitro diagnostic test, which is a physical component, not software.
Yes, this device is an IVD (In Vitro Diagnostic).
The "Intended Use / Indications for Use" section explicitly states: "N Latex Lp(a) Reagent is an in vitro diagnostic test for the quantitative determination of Lipoprotein(a) [Lp(a)] in human serum or plasma."

Intended Use / Indications for Use
N Latex Lp(a) is an in vitro diagnostic reagent for the quantitative determination of lipoprotein(a) [Lp(a)] in human serum and heparinized plasma by means of particle enhanced immunonephelometry using BN™ Systems. Measurement of Lp(a) aids in the identification of individuals at risk from cardiovascular disease in specific populations when used in conjunction with clinical evaluation.

Device Description
Polystyrene latex particles coated with specific antibodies to human Lp(a) are agglutinated when mixed with samples containing Lp(a). The intensity of scattered light in the BN™ Systems depends on the Lp(a) concentration in the sample. The concentration can therefore be determined by comparison with dilutions of a standard of known concentration.

Summary of Performance Studies
Correlation: The N Latex Lp(a) assay was compared to a commercially available Lp(a) immunonephelometric method by evaluating 86 laboratory serum samples ranging from 0.02 to 1.31 g/L.
Precision: The N Latex Lp(a) Reagent was used to measure the N Lp(a) Control SY and 6 patient samples or pools with Lp(a) concentrations between 0.29 and 1.77 g/L and yielded coefficients of variation between 1.8 and 4.1% for the intra-assay precision (n=20). N Lp(a) Control SY and 5 patient samples or pools with Lp(a) concentrations between 0.17 and 1.75 g/L were used to determine the inter-assay reproducibility (n=10) and the coefficients of variation were between 2.8 and 5.3%.
Key Metrics
Correlation coefficient of 0.96 was obtained with a y-intercept value of -0.005 and a slope of 0.92 (Passing-Bablok).
Intra-assay precision (n=20) coefficients of variation between 1.8 and 4.1%.

Measurement of Lp(a) aids in the identification of individuals at risk from cardiovascular disease in specific populations when used in conjunction with clinical evaluation.
Medical device to which equivalence is claimed and comparison information: 6.
There are a number of in vitro diagnostic products in commercial distribution, which employ immunoassay techniques for the quantitative determination Lp(a) in human serum or plasma. One such product is the Beckman Coulter Array® System LPA assay (K000121). The N Latex Lp(a) Reagent is substantially equivalent in intended use and results obtained to the Array System LPA assay. The N Latex Lp(a) Reagent, like the Array® System LPA assay is intended to be used for the quantitative determination of Lp(a) activity in human serum or plasma.
