Intended Use
The Access TSH (3rd IS) assay is a paramagnetic particle, chemiluminescent immunoassay for the quantitative determination of human thyroid-stimulating hormone (thyrotropin, TSH, hTSH) levels in human serum and plasma using the Access Immunoassay Systems. Measurements of thyroid stimulating hormone produced by the anterior pituitary are used in the diagnosis of thyroid or pituitary disorders. This assay is capable of providing 3rd generation TSH results. The DxI 9000 Access Immunoassay Analyzer is an in vitro diagnostic device used for the quantitative, semiquantitative, or qualitative determination of various analyte concentrations found in human body fluids.
Device Description
Access TSH (3rd IS) assay is a two-site immunoenzymatic ("sandwich") assay. The Access TSH (3rd IS) reagent kit is in a liquid ready-to-use format designed for optimal performance on Beckman Coulter's immunoassay analyzers. Each reagent kit contains two reagent packs. Other items needed to run the assay include substrate, calibrators and wash buffer. The Dxl 9000 Access Immunoassay Analyzer is a fully automated, continuous, random-access sample processing and analysis instrument. The Dxl 9000 Access Immunoassay Analyzer uses enzyme immunoassays (utilizing paramagnetic particle solid phase and chemiluminescent detection) for the quantitative, semi-quantitative or qualitative determination of various analyte concentrations found in human body fluids.

No
The description focuses on the immunoassay technology and the automated analyzer, with no mention of AI or ML in the intended use, device description, or performance studies.

No
The device is described as an "in vitro diagnostic device" used for quantitative, semiquantitative, or qualitative determination of various analyte concentrations in human body fluids, specifically for measuring TSH levels to aid in the diagnosis of thyroid or pituitary disorders. This indicates it is for diagnostic purposes, not for treating or rehabilitating a condition, which is characteristic of a therapeutic device.

Yes
The "Intended Use / Indications for Use" section explicitly states that the "Access TSH (3rd IS) assay" is used in the "diagnosis of thyroid or pituitary disorders" and that the "DxI 9000 Access Immunoassay Analyzer is an in vitro diagnostic device."

No

The device description clearly outlines a physical immunoassay kit (reagents) and a physical analyzer instrument (DxI 9000 Access Immunoassay Analyzer), indicating it is a hardware-based system with associated software, not a software-only device.

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

Here's why:

  • Intended Use/Indications for Use: The description explicitly states the assay is for the "quantitative determination of human thyroid-stimulating hormone... in human serum and plasma". It also mentions that these measurements "are used in the diagnosis of thyroid or pituitary disorders." This clearly indicates the device is intended for use in examining specimens derived from the human body to provide information for diagnostic purposes.
  • Device Description: The description of both the Access TSH (3rd IS) assay and the DxI 9000 Access Immunoassay Analyzer mentions they are used for determining analyte concentrations in "human body fluids".
  • DxI 9000 Access Immunoassay Analyzer Description: This description explicitly states that the analyzer "is an in vitro diagnostic device".
  • Predicate Device: The predicate device listed, K153651 Access TSH (3rd IS) Assay, is also an IVD.

All of these points align with the definition of an In Vitro Diagnostic device, which is a medical device intended for use in vitro for the examination of specimens, including blood and tissue samples, derived from the human body, solely or principally for the purpose of providing information concerning a physiological or pathological state, or concerning a congenital abnormality, or to determine the safety and compatibility of any tissue or organ for transplantation.

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

Method Comparison: A method comparison study was performed to compare the Access TSH (3rd IS) assay on Dxl 9000 to the predicate device. A total of one hundred and eleven (111) serum samples falling within the measuring range of the Access TSH (3rd IS) assay were evaluated. The results of the method comparison study met the acceptance criteria of R2 ≥ 0.90 and slope 1.00 ± 0.10.

Imprecision: On the Dxl 9000 Access Immunoassay Analyzer, within-laboratory (total) % CV ranged from 2.5% to 4.5%, for TSH concentrations > 0.02 µlU/mL. The within-laboratory (total) SD ranged from 0.0007 to 0.0014 for TSH concentrations ≤ 0.02 mlU/mL.

Reproducibility: The Access TSH (3rd IS) assay is designed to meet the requirements for reproducibility on the Dxl 9000 Access Immunoassay Analyzer with an SD ≤ 0.0038 for values ≤ 0.02 ulU/mL and CV 0.02 ulU/mL.

Limit of Blank (LoB): The LoB for TSH (3rd IS) is 0.002 µIU/mL on Dxl 9000 Access Immunoassay Analyzer.

Limit of Detection (LoD): The LoD estimate for the TSH (3rd IS) assav is 0.003 w/U/mL on Dxl 9000 Access Immunoassay Analyzer.

Limit of Quantitation (LoQ): The maximum LoQ determined for the TSH (3w/S) assay is 0.001 µlU/mL on Dxl 9000 Access Immunoassay Analyzer). Following the CLSI EP17-A2 recommendation that the LoQ must be greater than or equal to LoD, the LoQ value is reported as 0.003 µIU/mL to align with LoD.

Substantial Equivalence Comparison Conclusion

Beckman Coulter's TSH (3rd IS) Assay on the Dxl 9000 Access Immunoassay Analyzer is substantially equivalent to the Access TSH (3rd IS) Assay on the Access 2 Immunoassay System as demonstrated through the information and data provided in this submission. The performance testing presented in this submission provides evidence that the device is safe and effective in its intended use.
