More Information

No
The summary describes a standard immunoassay system and does not mention any AI or ML components.

No
The device is an in vitro diagnostic (IVD) immunoassay system used for the quantitative determination of thyroglobulin antibody levels to aid in the diagnosis of certain thyroid disorders. It does not directly provide therapy or treatment.

Yes

The "Intended Use / Indications for Use" section explicitly states that the assay "may aid in the diagnosis of certain thyroid disorders." This directly indicates its role in diagnosis.

No

The device description explicitly states that the system comprises reagents, calibrators, and an analyzer, which are all hardware components.

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

Here's why:

  • Intended Use: The intended use explicitly states it's for the "quantitative determination of thyroglobulin antibody levels in human serum and plasma." This indicates it's used to analyze biological samples in vitro (outside the body).
  • Device Description: The description mentions "reagents," "calibrators," and an "Immunoassay Analyzer," which are all components typically used in laboratory testing of biological samples.
  • Performance Studies: The performance studies describe analytical characteristics like sensitivity, specificity, precision, and method comparison using serum samples. These are standard evaluations for IVD devices.
  • Predicate Device: The mention of a "Predicate Device" (K894203; Kalibre-RTM Thyroglobulin Antibody (TgAb) RIA Kit) is a strong indicator that this device is being compared to a previously cleared IVD device, a common practice in regulatory submissions for IVDs.

All these factors point to the device being used to perform tests on biological samples in vitro to provide information for diagnostic purposes, which is the definition of an In Vitro Diagnostic device.

Summary of Performance Studies

Analytical Specificity: There was no significant interference from potential sample contaminants (total protein, bilirubin, hemoglobin, and triglycerides). Additionally, only one discrepancy between interpretations positive and negative was found between the Access and Kronus thyroglobulin assays for samples form persons with autoimmune disease.

Analytical Sensitivity: The lowest detectable level of thyroglobulin antibody distinguishable from zero (Access Thyroglobulin Calibrator Zero) with 95% confidence was determined to be 1.5 IU/mL. An analytical sensitivity of 2.2 IU/mL will be used in the Access Thyroglobulin Antibody labeling.

Dilution Recovery: Various dilutions of serum samples and serum sample pools were analyzed. The overall mean recovery of the samples was 95% with individual mean sample recoveries varying between 90% and 100%.

Precision: Within run imprecision ranged from 3.99 to 5.04 % CV, between run imprecision ranged from 1.95 to 4.66 % CV, and total imprecision ranged from 4.47 to 6.74 % CV at levels ranging between 34.1 and 1,693 IU/ml.

Hook Effect: The Access Thyroglobulin Antibody assay demonstrated no hook to 350,000 IU/ml.

Relative Sensitivity and Specificity: A total of 296 serum samples (99 with Graves' disease, 97 with Hashimoto's disease, and 100 normals) were used to calculate relative sensitivity and specificity for the Access vs. the Kronus thyroglobulin antibody assays. The study showed good relative sensitivity (79.0%) and relative specificity (87.6%) between the methods.

Method Comparison: A comparison of thyroglobulin antibody values from 276 samples, ranging from approximately

§ 866.5870 Thyroid autoantibody immunological test system.

(a)
Identification. A thyroid autoantibody immunological test system is a device that consists of the reagents used to measure by immunochemical techniques the thyroid autoantibodies (antibodies produced against the body's own tissues). Measurement of thyroid autoantibodies may aid in the diagnosis of certain thyroid disorders, such as Hashimoto's disease (chronic lymphocytic thyroiditis), nontoxic goiter (enlargement of thyroid gland), Grave's disease (enlargement of the thyroid gland with protrusion of the eyeballs), and cancer of the thyroid.(b)
Classification. Class II (performance standards).
