Intended Use
For the quantitative determination of free thyroxine (FT4) in serum using the Ciba Corning Automated Chemiluminescence Systems.
Device Description
The Ciba Corning ASC FrT4 Immunoassay is a competitive immunoassay. FT4 in the-sample competes with the acridinium ester (AE-labeled T4 (Lite Reagent) for a limited amount of polyclonal rabbit anti-T4 antibody, which is covalently coupled to paramagnetic particles (solid phase). An indirect relationship exists between the FT4 in a sample and the relative light units (RLUs) detected.
More Information

No
The description details a standard competitive immunoassay based on chemical reactions and light detection, with no mention of AI or ML algorithms for data analysis or interpretation.

No
This device is for the quantitative determination of free thyroxine (FT4) in serum, which is a diagnostic function, not a therapeutic one. It measures a substance to help understand a medical condition, rather than treating it.

Yes
The device is described as an immunoassay for the quantitative determination of free thyroxine (FT4) in serum, which is generally used to aid in the diagnosis of thyroid disorders. The "Intended Use / Indications for Use" directly states its purpose for quantitative determination in serum.

No

The device description clearly indicates it is an immunoassay that uses chemical reagents (acridinium ester, polyclonal rabbit anti-T4 antibody) and paramagnetic particles, which are physical components, not software.

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

Here's why:

  • Intended Use: The intended use explicitly states "For the quantitative determination of free thyroxine (FT4) in serum". This indicates the device is used to analyze a sample taken from the human body (serum) to provide information about a physiological state (FT4 levels).
  • Device Description: The description details a "competitive immunoassay" that uses "serum" as the sample. This is a common method used in IVD devices to measure substances in biological fluids.
  • Performance Studies: The inclusion of performance studies like Accuracy and Precision, and metrics like Sensitivity, are typical for IVD devices to demonstrate their analytical performance.
  • Predicate Device: The mention of a "Predicate Device" (Amerlex-MAB FT4) is a strong indicator that this device is being compared to an existing, legally marketed IVD device for regulatory purposes.

All these elements align with the definition and characteristics of an In Vitro Diagnostic device.

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

Sensitivity:
The ACS FrT4 immunoassay measures FT4 concentrations up to 11.0 ng/dl with a minimum detectable concentration of 0.1 ng/dl.

Accuracy:
For 74 samples in the range of 0.62 to 4.26 ng/dl, the correlation between the ACS FrT4 immunoassay and the RIA reference method assay is described by the equation:
ACS FrT4 = 1.06 (RIA) - 0.33
Correlation coefficient (r) = 0.97

Precision:
Total precision (Total % CV) ranged form 2.81 to 4.65.

§ 862.1660 Quality control material (assayed and unassayed).

(a)
Identification. A quality control material (assayed and unassayed) for clinical chemistry is a device intended for medical purposes for use in a test system to estimate test precision and to detect systematic analytical deviations that may arise from reagent or analytical instrument variation. A quality control material (assayed and unassayed) may be used for proficiency testing in interlaboratory surveys. This generic type of device includes controls (assayed and unassayed) for blood gases, electrolytes, enzymes, multianalytes (all kinds), single (specified) analytes, or urinalysis controls.(b)
Classification. Class I (general controls). Except when intended for use in donor screening tests, quality control materials (assayed and unassayed) are exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 862.9.
