Intended Use
The ATAC PAK BUN Reagent Kit is intended for the quantitative determination of urea nitrogen in serum, plasma and urine. Urea nitrogen results are used in the diagnosis and treatment of certain renal and metabolic diseases.
Device Description
The ATAC PAK BUN Reagent determines urea nitrogen through the enzymatic action of urease and glutamate delydrogenase. The resulting decrease in absorbance at 340 nm is proportional to the urea nitrogen concentration of the sample.

No
The summary describes a reagent kit for a chemistry analyzer, focusing on enzymatic reactions and absorbance measurements. There is no mention of AI or ML.

No.
This device is a reagent kit used for the quantitative determination of urea nitrogen in biological samples, which aids in the diagnosis and treatment of diseases, but it does not directly provide therapy.

Yes
The "Intended Use / Indications for Use" section states: "Urea nitrogen results are used in the diagnosis and treatment of certain renal and metabolic diseases." This indicates its use in identifying or confirming a disease or condition.

No

The device is a reagent kit, which is a chemical substance used in a chemical reaction, not a software program.

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

Here's why:

  • Intended Use: The "Intended Use / Indications for Use" section explicitly states that the kit is "intended for the quantitative determination of urea nitrogen in serum, plasma and urine." This is a classic definition of an in vitro diagnostic test, as it analyzes biological samples (serum, plasma, urine) outside of the body to provide information about a patient's health.
  • Purpose: The intended use also states that the results "are used in the diagnosis and treatment of certain renal and metabolic diseases." This further confirms its diagnostic purpose.
  • Device Description: The description explains how the kit works by analyzing the sample through enzymatic action and measuring absorbance changes. This is a common method used in IVD tests.
  • Performance Studies: The document includes performance studies (linearity, precision, comparison to another method) which are typical for demonstrating the analytical performance of an IVD.
  • Predicate Device: The mention of a "Predicate Device" (HiChem BUN Reagent Kit) is a strong indicator that this device is being submitted for regulatory clearance as an IVD, as predicate devices are used for comparison in the regulatory process for IVDs.

Summary of Performance Studies

The effectiveness of ATAC PAK BUN Reagent Kit on the ATAC 8000 Random Access Chemistry System is shown by the following studies.

The recovery of urea nitrogen using the ATAC PAK BUN Reagent is linear from 2 to 100 mg/dL, as shown by the recovery of linearity standards that span the usable range. Regression statistics, which compare standard values, are shown below.
(ATAC Recoveries) = 0.6 mg/dL + 0.9775 x (Standard Value), sy.x = 1.2 mg/dL, n = 50

Precision is demonstrated by the replicate assay of commercially available control serum. Precision statistics, calculated analogous to the method described in NCCLS Guideline EP3-T, are shown below.

Urine 160210.42.1%0.52.5%
Urine 260801.01.3%1.41.7%

Mixed serum, plasma and diluted urine specimens, collected from adult patients, were assayed for urea nitrogen using the ATAC 8000 Random Access Chemistry System and another commercially available method. Results were compared by least squares linear regression and the following statistics were obtained.

Serum/Plasma Comparison ATAC 8000 = 1.2 mg/dL + 0.977 x Competitive Reagent r = 0.996 n = 217 range = 5 - 100 mg/dL

Urine Comparison
ATAC 8000 = 1.9 mg/dL + 0.9525 x Competitive Reagent n = 92 range = 19 - 100 mg/dL r = 0.991

The detection limit claim of 2 mg/dL is documented through the repetitive assay of a diluted serum control. The observed standard deviation of a 30 replicate within run precision study was 0 mg/dL. Consequently, the detection limit is reported as twice the round-off error of the assay.

The 14 day on board reagent stability and 14 day calibration stability claims are documented through the assay of serum controls and urine pools over the claimed periods. In all cases, the total imprecision of urea nitrogen recoveries over the test periods are less than 3 mg/dL or 3%.
