Intended Use
Immunoturbidometric assay for the quantitative in-vitro determination of Prealbumin. Immunological latex agglutination test for the in vitro quantitative determination of prealbumin in human serum and plasma. Measurement of prealbumin levels in serum may aid in the assessment of the patient's nutritional status.
Device Description
The Prealbumin determination is based upon turbidimetric immunoinhibition (TINIA) using a serum or plasma blood sample. The sample containing Prealbumin is transferred into a TRIS buffer solution (R₁ reagent). In the second step, an aliquot of solution of polyclonal anti-human Prealbumin antibodies (R₂ reagent) is added to mixture of the first step. The antibody binds to the Prealbumin in the sample to form "aggregates" such that the amount of aggregate formed is proportionate to the amount of Prealbumin present in the sample. The resulting agglutination complex is measured turbidimetrically whereby increased turbidity is reflected through an increase in optical density. Therefore, the amount of Prealbumin in the sample is directly proportional to the amount of turbidity formed.

No
The device description details a standard immunoturbidimetric assay based on chemical reactions and optical density measurements, with no mention of AI or ML algorithms for data processing or interpretation.

No.
This device is an in-vitro diagnostic assay used to quantify prealbumin levels, which aids in assessing nutritional status. It does not directly treat or alleviate a disease or condition.

Yes

The device quantitatively determines prealbumin levels in human serum and plasma, which aids in assessing a patient's nutritional status. This information can be used by a medical professional to make a diagnosis regarding malnutrition or other health conditions related to prealbumin levels.

No

The device description clearly outlines a laboratory assay that uses reagents and measures turbidity, indicating a physical, in-vitro diagnostic device, not software.

Based on the provided information, this device is indeed an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use / Indications for Use: The description explicitly states "Immunoturbidometric assay for the quantitative in-vitro determination of Prealbumin" and "Immunological latex agglutination test for the in vitro quantitative determination of prealbumin in human serum and plasma." The phrase "in vitro" is a key indicator of an IVD.
  • Device Description: The description details a test performed on a "serum or plasma blood sample," which is a biological sample taken from the body and tested outside of it. This aligns with the definition of an in vitro test.
  • Measurement of Prealbumin: The purpose is to measure a substance (Prealbumin) in a biological sample to aid in the assessment of a patient's nutritional status. This is a common application of IVDs.

Therefore, all the provided information points to this device being an In Vitro Diagnostic.
