No
The device description details a chemical and immunonephelometric process for measuring homocysteine, with no mention of AI or ML algorithms for analysis or interpretation.
No
The device is an in vitro diagnostic reagent used to quantify total homocysteine for diagnosis and treatment assistance, not a device that directly provides therapy.
Yes
The "N Latex HCY" is described as an "in vitro diagnostic reagent" and its intended use explicitly states, "The device can assist in the diagnosis and treatment of patients suspected of having hyperhomocysteinemia and homocystinuria." This directly indicates a diagnostic purpose.
No
The device description details a chemical reaction and particle aggregation process, indicating it is a physical in vitro diagnostic reagent kit, not a software-only device.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use/Indications for Use: The description explicitly states "In vitro diagnostic reagents for the quantitative determination of total homocysteine (HCY) in human serum, heparinized plasma and EDTA plasma..." and "The device can assist in the diagnosis and treatment of patients suspected of having hyperhomocysteinemia and homocystinuria." This clearly indicates the device is intended for use outside of the body to diagnose or aid in the diagnosis of a disease or condition.
- Device Description: The description details a laboratory test method (particle-enhanced immunonephelometry) performed on biological samples (serum, plasma).
- Predicate Device: The mention of a predicate device (K992858 Abbott IMx Homocysteine Assay) which is also an IVD, further supports the classification of this device as an IVD.
The other listed components (N Protein Standard SL and N/T Protein Control SL/L, M and H) are also described as reagents and controls used in conjunction with the primary device for in vitro diagnostic testing.

Device Description
Bound homocysteine in the sample is reduced to free homocysteine by the action of dithiothreitol, and converted enzymatically to S-adenosyl-homocysteine (SAH) in the next step. Conjugated S-adenosyl-cysteine (SAC), added at the onset of the reaction, competes with the SAH in the sample for bonding by anti-SAH antibodies bound to polystyrene particles. In the presence of SAH, there is either no aggregation or a weaker aggregation of particles. In the absence of SAH in the sample, an aggregation of the polystyrene particles by the conjugated SAC occurs. The higher the SAH content of the reaction mixture is, the smaller the scattered light signal. The result is evaluated by comparison with a standard of known concentration.

§ 862.1377 Urinary homocystine (nonquantitative) test system.
(a)
Identification. A urinary homocystine (nonquantitative) test system is a device intended to identify homocystine (an analogue of the amino acid cystine) in urine. The identification of urinary homocystine is used in the diagnosis and treatment of homocystinuria (homosystine in urine), a heritable metabolic disorder which may cause mental retardation.(b)
