Intended Use
The Diazyme Glycated Serum Protein POC Test Kit is intended for the quantitative determination of glycated serum proteins (GSP; fructosamine) in serum. Fructosamine is representative of blood glucose levels over the course of 2-3 weeks. The measurement of glycated serum proteins is useful for monitoring diabetic patients. For in vitro diagnostic use only.
Device Description
Fructosamine is formed due to a non-enzymatic Maillard reaction between glucose and amino acid residues of serum proteins. It is reported in medical literature that 80% of measured glycated serum proteins are glycated albumins. In diabetic patients, elevated blood glucose levels correlate with increased fructosamine formation. Glycated serum proteins (GSP; fructosamine) are a medium term indicator of diabetic control (2-3 weeks). The Diazyme Glycated Serum Protein POC Assay uses proteinase K to digest GSP into low molecular weight glycated protein fragments (GPF), and uses Diazyme's specific fructosamiase™, a microorganisms originated amadoriase to catalyze the oxidative degradation of Amadori product GPF to yield peptide fragments (PF) or amino acids, glucosone and H2O2. The H2O2 released is measured by a colorimetric Trinder end-point reaction. The absorbance at 546 nm is proportional to the concentration of glycated serum proteins. The SMART analyzer calculates the GSP concentrations of patient serum specimens by use of a lot specific calibration curve. The lot specific curve is represented in a Calibration card (RFID) provided with each GSP POC Test Kit. SMART Analyzer (K092911) is a compact cuvette based spectrophotometer (10 inches x 5.5 inches x 5.5 inches) machine for point-of-care testing designed to analyze readings from single use reagent cuvette. The instrument only uses the Diazyme Reagent System (DRS) cuvette and caps and performs assay with a preprogrammed Radio Frequency ID (RFID) card. The DRS cuvette is supplied prefilled with Reagent 1 (R1) and the DRS cap is supplied prefilled with Reagent 2 (R2). The DRS cuvette and caps are kept separate until use. Users are instructed (see proposed labeling) to add 40ul of sample to the DRS cuvette prefilled with R1 containing proper buffer. Users are then instructed to snap in place DRS cap and insert into analyzer. The instrument warms the cuvette to 37°C and after a predefined period adds the reagent R2 found in the DRS cap. The reagents and samples are mixed magnetically and absorbance readings are taken at 546nm. The lot specific RFID card contains reagent addition time, mixing time, reading time and lot specific calibration curve. The Diazyme GSP POC Test Kit system thus consists of the following: - . GSP POC Test Kit. Reagents are provided in prefilled tubes, cuvettes and cuvette caps. The DRS cuvette and cuvette caps can only work with the SMART analyzer.
More Information

No
The description details a chemical assay and spectrophotometric analysis with calculations based on a pre-programmed calibration curve from an RFID card. There is no mention of AI or ML algorithms for data analysis or interpretation.

No

The device is an in vitro diagnostic (IVD) test kit used for the quantitative determination of glycated serum proteins to monitor diabetic patients, not to treat them.

Yes

The device is intended for the quantitative determination of glycated serum proteins in serum, which is useful for monitoring diabetic patients, directly indicating its purpose in diagnosing or monitoring a medical condition.

No

The device description clearly outlines hardware components including a spectrophotometer (SMART Analyzer), reagent cuvettes, and caps, which are integral to the device's function. While software is used for calculations and controlling the analyzer, it is 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 only." This is a clear declaration of its intended purpose.
  • Function: The device is designed to quantitatively determine glycated serum proteins (GSP; fructosamine) in serum. This is a measurement performed on a biological sample (serum) outside of the body to provide information for the diagnosis or monitoring of a medical condition (diabetes).
  • Monitoring Diabetic Patients: The intended use also states that the measurement is "useful for monitoring diabetic patients," which is a common application of IVD devices.
  • Device Description: The description details the biochemical reactions and measurement method used to analyze the serum sample, which is characteristic of an IVD assay.
  • Components: The system includes reagents and a specialized analyzer designed to work with those reagents to perform the diagnostic test.

All of these factors align with the definition of an In Vitro Diagnostic device.

Executive Summary

Detailed performance characteristics and comparison analysis are given in this filing that demonstrates substantial equivalence of the GSP POC Assay Kit to predicate device that is currently being marketed. The performance characteristics of the GSP POC Assay Kit are substantially similar to that of the approved predicate device (K110188). Performance data and risk analysis indicates that differences should not affect the safety and effectiveness of the GSP POC Assay and offers POL users an in vitro diagnostic device system to measure GSP in human serum samples.

Clinical Significance

Fructosamine is formed due to a non-enzymatic Maillard reaction between glucose and amino acid residues of serum proteins. It is reported in medical literature that 80% of measured glycated serum proteins are glycated albumins. In diabetic patients, elevated blood glucose levels correlate with increased fructosamine formation. Glycated serum proteins (GSP; fructosamine) are a medium term indicator of diabetic control (2-3 weeks).

Assay Principle

The Diazyme Glycated Serum Protein POC Assay uses proteinase K to digest GSP into low molecular weight glycated protein fragments (GPF), and uses Diazyme's specific fructosamiase™, a microorganisms originated amadoriase to catalyze the oxidative degradation of Amadori product GPF to yield peptide fragments (PF) or amino acids, glucosone and H2O2. The H2O2 released is measured by a colorimetric Trinder end-point reaction. The absorbance at 546 nm is proportional to the concentration of glycated serum proteins. The SMART analyzer calculates the GSP concentrations of patient serum specimens by use of a lot specific calibration curve.

SMART Analyzer (K092911) is a compact cuvette based spectrophotometer (10 inches x 5.5 inches x 5.5 inches) machine for point-of-care testing designed to analyze readings from single use reagent cuvette. The instrument only uses the Diazyme Reagent System (DRS) cuvette and caps and performs assay with a preprogrammed Radio Frequency ID (RFID) card. The DRS cuvette is supplied prefilled with Reagent 1 (R1) and the DRS cap is supplied prefilled with Reagent 2 (R2). The DRS cuvette and caps are kept separate until use. Users are instructed (see proposed labeling) to add 40ul of sample to the DRS cuvette prefilled with R1 containing proper buffer.
