No
The description details a standard immunonephelometry assay based on light scattering and comparison to a standard, with no mention of AI or ML terms or processes.
No.
The device is an in vitro diagnostic reagent used to quantify alpha-1 antitrypsin, aiding in the diagnosis of conditions like liver cirrhosis and pulmonary emphysema. It does not provide therapeutic treatment.
Yes
The "Intended Use / Indications for Use" section explicitly states that the determination of α-antitrypsin "aids in the diagnosis of several conditions," which directly aligns with the definition of a diagnostic device.
No
The device description clearly states it is an in vitro diagnostic reagent used with a specific hardware system (BN™ Systems) for immunonephelometry, which is a laboratory technique involving physical components and chemical reactions. It is not solely software.
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 a -antitrypsin in human serum, heparinized and EDTA plasma". This clearly indicates the device is intended for use outside of the body to diagnose or aid in the diagnosis of medical conditions.
- Device Description: The description details a method for analyzing human body fluids (serum, plasma) using an immunochemical reaction to measure the concentration of a specific protein. This is a typical characteristic of an in vitro diagnostic test.
- Predicate Device: The mention of a predicate device (K860894; N Antisera to Human a - Antitrypsin) which is also an IVD further supports this classification.
The information provided aligns with the definition of an In Vitro Diagnostic device.

Intended Use / Indications for Use
In vitro diagnostic reagents for the quantitative determination of a-antitrypsin in human serum, heparinized and EDTA plasma by means of immunonephelometry on the BN™ Systems. The measurement of a-antitrypsin aids in the diagnosis of several conditions including adult cirrhosis of the liver. In addition, a₁-antitrypsin deficiency has been associated with pulmonary emphysema in conjunction with other laboratory and clinical findings.

Device Description
Proteins contained in human body fluids form immune complexes in an immunochemical reaction with specific antibodies. These complexes statter a beam of light passed through the sample. The intensity of the scattered light is proportional to the concentration of the relevant protein in the sample. The result is evaluated by comparison with a standard of known concentration.

§ 866.5130
Alpha -1-antitrypsin immunological test system.(a)
Identification. Analpha -1-antitrypsin immunological test system is a device that consists of the reagents used to measure by immunochemical techniques thealpha -1-antitrypsin (a plasma protein) in serum, other body fluids, and tissues. The measurements aid in the diagnosis of several conditions including juvenile and adult cirrhosis of the liver. In addition,alpha -1-antitrypsin deficiency has been associated with pulmonary emphysema.(b)
