No
The description focuses on standard nephelometry methodology and mathematical calculations of reaction rates, with no mention of AI or ML terms or concepts.
No
This device is for quantitative determination of immunoglobulin M in human serum or CSF, which is a diagnostic function, not a therapeutic one.
Yes
The device quantitatively determines immunoglobulin M in human serum or cerebrospinal fluid (CSF), which is a measurement used for diagnostic purposes.
No
The device description explicitly details hardware components like a laser, detector, and reaction cuvette, and describes a physical process (rate nephelometry) involving light scattering and chemical reactions. It is a reagent used with a larger hardware system.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states the quantitative determination of immunoglobulin M in human serum or cerebrospinal fluid (CSF). This involves testing samples taken from the human body.
- Device Description: The description details a system that analyzes biological samples (serum and CSF) using a specific methodology (rate nephelometry) to measure a substance (immunoglobulin M) within those samples.
- Performance Studies: The document includes performance studies (method comparison, precision, sensitivity) which are typical for IVD devices to demonstrate their analytical performance.
- Predicate Device: The mention of a predicate device (K993547) which is also an IMMAGE system reagent and calibrator further supports its classification as an IVD.
The core function of the device is to perform a test on a biological sample in vitro (outside the body) to provide information about a patient's health status (in this case, the concentration of immunoglobulin M). This aligns directly with the definition of an In Vitro Diagnostic device.

Device Description
The IMMAGE System Low Concentration Immunoglobulin M (IGMLC) Reagent, when used in conjunction with IMMAGE Immunochemistry Systems and Cerebrospinal Fluid Protein Calibrator is intended for the quantitative determination of human Immunoglobulin M in serum and cerebrospinal fluid (CSF) by rate nephelometry.
The IMMAGE Immunochemistry System (cleared under K962294) is a high throughput, random access analyzer that uses rate nephelometry methodology to measure human immunoglobulin M concentration in serum and CSF samples. The IMMAGE Immunochemistry System automatically dilutes and delivers sample to the reaction cuvette along with reagents and other reaction constituents.
During the reaction, particle bound anti-IgM antibody binds to IgM molecules in the sample via an antigen-antibody reaction. This results in the formation of insoluble complexes causing an increase in light scatter. The rate of increase in light scattered from the particles suspended in solution is directly proportional to the concentration of immunoglobulin M in the sample.
The rate nephelometer measures the increase in the intensity of light scattered by particles suspended in a cuvette. The light source for the rate nephelometer is a 670 nm wavelength laser. The detector is placed at a 90° angle from the incident beam to measure light increase. At the end of the reaction, the system mathematically calculates the rate of change of the scatter signal.

§ 866.5510 Immunoglobulins A, G, M, D, and E immunological test system.
(a)
Identification. An immunoglobulins A, G, M, D, and E immunological test system is a device that consists of the reagents used to measure by immunochemical techniques the immunoglobulins A, G, M, D, an E (serum antibodies) in serum. Measurement of these immunoglobulins aids in the diagnosis of abnormal protein metabolism and the body's lack of ability to resist infectious agents.(b)
Classification. Class II (performance standards).

IMMAGE® Immunochemistry Systems IGMLC Reagent, when used in conjunction with IMMAGE® Immunochemistry Systems and Cerebrospinal Fluid Protein Calibrator, is intended for quantitative determination of immunoglobulin M in human serum or cerebrospinal fluid (CSF) by rate nephelometry.
Clinical Siqnificance:
The concentration ratio of immunoglobulins in CSF and serum detects increased permeability of the blood-CSF barrier and intrathecal synthesis of immunoqlobulins. 1.2
The permeability of the blood-CSF barrier to plasma increases due to brain tumor, intracerebral hemorrhage, meningitis, encephalitis, and bacterial infections. The intrathecal synthesis of immunoglobulins is important in the diagnosis of diseases of the Central Nervous System (CNS) 3
