The device description explicitly states that globulin is calculated as the difference between total protein and albumin concentrations, which is a simple arithmetic calculation, not AI/ML. There are no mentions of AI, ML, or related terms, nor any descriptions of training or test sets typically associated with AI/ML development.
No
The device is for in vitro diagnostic use to aid in diagnosis and treatment, not to directly treat patients.
Yes
This device is for "in vitro diagnostic use" and aids "in the diagnosis and treatment of patients with numerous illnesses".
No
The device description explicitly states it uses the "CareSide™ Analyzer" and "Total Protein and Albumin cartridge test results" to perform calculations. This indicates the device is part of a system that includes hardware (the analyzer and cartridges), not a standalone software-only device.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The "Intended Use / Indications for Use" section explicitly states "For in vitro diagnostic use".
- Function: The device calculates globulin and albumin/globulin ratio from results generated by other IVD tests (Total Protein and Albumin cartridges) on the CareSide Analyzer. This process is performed in vitro (outside of the living body) on patient samples.
- Purpose: The results are used by professionals "to aid in the diagnosis and treatment of patients with numerous illnesses". This is a core function of IVD devices.

Intended Use / Indications for Use
The CareSide™ Globulin product is intended for in vitro diagnostic use when used in conjunction with the Exigent Diagnostics CareSide™ Analyzer to calculate globulin and albumin/globulin ratio from albumin and total protein results. When an CareSide™ Analyzer operator performs both a total protein test (Product Code: TP) and an albumin test (Product Code: ALB) on a single patient sample, the CareSide™ Analyzer automatically calculates the Globulin measurement and the Albumin to Globulin ratio (A/G Ratio). Both calculations aid in the diagnosis and treatment of patients with numerous illnesses including severe liver and renal disease, multiple myeloma, and other disorders of blood globulins.
This product is indicated for use with patients with numerous illnesses including severe liver and renal disease, multiple myeloma, and other disorders of blood globulins.

Device Description
The CareSide™ Analyzer uses the Total Protein and Albumin cartridge test results from a single patient sample to determine the globulin concentration and A/G Ratio. Globulin is calculated as the difference between the total protein and albumin concentrations.
The CareSide™ Globulin is a calculated test hased upon whole blood, plasma or serum results from CareSide™ Total Protein and Albumin cartridges using only the CareSide™ Analyzer [510(k) pending]. The CareSide™ Globulin is an in vitro diagnostic product intended for the calculation of globulin in human serum, plasma, and whole blood. The principle of the calculation relies upon the following CareSide™ Total Protein and CareSide™ Albumin cartridges test reactions.

Substantial Equivalence Claim III.
- General equivaloncy claim A.
The ability to monitor analyte-specific biochemical reactions in dry film and other formats is widely recognized and has gained widespread acceptance for use in chemistry assays. Historically, globulin has been measured directly in a variety of ways, including electrophoretically, nephelometrically, turbidimetrically, and colorimetrically. However, direct measurement is no longer in common use. Rather, commercial in vitro diagnostic systems and clinical laboratories have, for many years, provided clinically useful results by calculating globulin results from albumin and total protein. Calculations of globulin from these dry film and other formats are similarly widely recognized.
Globulin in vitro diagnostic products are already on the U.S. market. These products utilize dry film and other formats. These products utilize the biuret reaction (reaction of protein peptide bonds with cupric ion in alkaline environment),
B. Specific equivalency claim
This CareSide™ Globulin calculation test is substantially cquivalent in principle, intended use, and clinical performance to the currently marketed Vitros slides for the quantitative measurement of total protein and albumin on the Vitros DT 60 II.

B. Test Summary
Globulin is a term for a subsct of serum proteins distinguished from the major plasma protein, serum albumin, by their electrophorctic properties. Most globulins have major carbohydrate components. Globulins are categorized by their clectrophoretic properties as, a, B, and y-globulins. a-Globulins include an-globulin and a2-globulin (a2glycoprotein, ceruloplasmin, and prothrombin). B-globulins consist of Bi-lipoproteins, transferrin, and plasminogen. y-globulins, which have molecular weights approximately 150,000, function as antibodies and occur in a very large number of different types. The quantitation of globulin (either indirect calculation or less commonly, direct measurement) is used to sid in the diagnosis of many disease states.
Globulins are elevated infections, most acute and chronic liver diseases, collagen disorders such as theumatoid arthritis and lupus crythematosis, and neoplastic diseases such as multiple myeloma, macroglobulinemia, and leukemia.
Although it is recommended that clinicians evaluate the level of globulin and albumin individually, many physicians additionally request the calculated ratio of albumin to globulin concentration for evaluation.
