Intended Use
The A/C Enzymatic Vitamin B6 Assay is intended for the quantitative in vitro diagnostic determination of pyridoxal 5'-phosphate (PLP, vitamin Bo) in EDTAhuman plasma. The device will be used to monitor PLP concentrations in plasma for aid in diagnosis of vitamin B6 deficiency. The A/C Enzymatic Vitamin B6 Assay is for IN VITRO DIAGNOSTIC USE ONLY.
Device Description
The A/C Enzymatic Vitamin B6 Assay is calibrated with external standardization and matrix-matched calibration solutions. Two sources of quality control material (A low and high level of PLP) are assaved in each run together with A/C Calibrators and samples for the verification of the accuracy and precision of the A/C Enzymatic Vitamin B6 Assay. The A/C Enzymatic Vitamin B6 Assay uses the apo form of recombinant PLPdependent enzyme, homocysteine-a.y-lyase (rHCYase). The restoration of enzymatic activity by reconstitution of the holo-enzyme is linearly dependent on the amount of PLP bound to apo-enzyme. Nanomolar concentrations of PLP can then be measured by the conversion of millimolar concentrations of homocysteine to hydrogen sulfide, which is determined using DBPDA, the combination of which forms a chromophore, the absorbance is read with 96-well plate absorbance reader. The A/C Enzymatic Vitamin B6 Assay is a three-step reaction with four reagents. which runs at 37°C or room temperature. The total assay takes 90 minutes. The assay can be performance on 96-well absorbance reader with 660-690m filter.

No
The description details a biochemical assay based on enzymatic reactions and absorbance measurements, with no mention of AI or ML.

No.
The device is an in vitro diagnostic (IVD) assay designed to quantify vitamin B6 (PLP) in plasma for diagnosis of a deficiency. It does not treat or cure a disease or condition.

Yes

The "Intended Use / Indications for Use" section explicitly states, "The A/C Enzymatic Vitamin B6 Assay is intended for the quantitative in vitro diagnostic determination... The device will be used to monitor PLP concentrations in plasma for aid in diagnosis of vitamin B6 deficiency. The A/C Enzymatic Vitamin B6 Assay is for IN VITRO DIAGNOSTIC USE ONLY." This directly indicates its role as a diagnostic device.

No

The device description clearly outlines a chemical assay involving reagents, enzymatic reactions, and measurement using a 96-well plate absorbance reader, indicating it is a hardware-based in vitro diagnostic device, not software only.

Yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Explicit Statement: The "Intended Use / Indications for Use" section clearly states: "The A/C Enzymatic Vitamin B6 Assay is intended for the quantitative in vitro diagnostic determination of pyridoxal 5'-phosphate (PLP, vitamin Bo) in EDTAhuman plasma." and "The A/C Enzymatic Vitamin B6 Assay is for IN VITRO DIAGNOSTIC USE ONLY."
  • Purpose: The device is used to measure a substance (PLP) in a biological sample (human plasma) to aid in the diagnosis of a medical condition (vitamin B6 deficiency). This is a core function of an IVD.
  • Sample Type: It analyzes a sample taken from the human body (plasma).
  • Setting: The intended user/care setting is explicitly stated as "IN VITRO DIAGNOSTIC USE ONLY," reinforcing its purpose in a laboratory or clinical setting for diagnostic testing.

The description of the assay method, reagents, and performance studies further supports its classification as an IVD, as these are typical components of a submission for an in vitro diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

To establish equivalence to an existing device, and thus establish the safety and effectiveness, the A/C Enzymatic Vitamin Bo Assay was compared to ALPCO Vitamin B6 REA method (K# 955561).

The comparison of the A/C Enzymatic Vitamin B6 Assay to the ALPCO Vitamin B6 REA assay was carried for fifty four EDTA-plasma samples. Each sample was analyzed in duplicate with both methods. The correlation and regression analysis yielded y = 0.969x + 7.6 with a correlation coefficient of r = 0.909. The bias analysis of both methods by the difference (A/C Enzymatic Bg – ALPCO Bg) vs PLPCO Bg REA is shown in the Difference plot. The range of values was 16.3 - 189.3 nmol/L (mean = 6.3) for the A/C Enzymatic Vitamin B6 Assay and 15.8 -185.8 mmol/l (mean = 68.7) for ALPCO Vitamin B& REA Assay. The average difference exhibited by A/C Enzymatic Vitamin B6 Assay and ALPCO B6 REA in this study was 2.42 nmol/L.
