The description focuses on a standard immunoassay technology and does not mention any AI or ML components.
No
Explanation: This device is for in vitro diagnostic testing, specifically for quantitative determination of TSH, which aids in assessment and diagnosis of thyroid status. While it assists in the treatment of thyroid disease, it does not directly perform a therapeutic function on a patient.
Yes
The "Intended Use / Indications for Use" section explicitly states that the device "is used as an aid in the assessment of thyroid status, diagnosis of thyroid disease, and treatment of thyroid disease," which are all diagnostic purposes.
No
The device description clearly states it is a Microparticle Enzyme Immunoassay (MEIA) and involves the quantitative determination of TSH in human serum or plasma, which are laboratory-based chemical processes requiring physical reagents and equipment, not solely software.
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 thyroid stimulating hormone (TSH) in human serum or plasma". This is a test performed on biological samples taken from the body.
- Method: It uses a "Microparticle Enzyme Immunoassay (MEIA)", which is a laboratory technique used to measure substances in biological fluids.
- Purpose: The assay is used "as an aid in the assessment of thyroid status, diagnosis of thyroid disease, and treatment of thyroid disease". This indicates it's used for medical purposes to provide information about a patient's health condition.
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 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 compatibility of tissues, organs or blood with potential recipients, or to monitor therapeutic measures.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Substantial equivalence has been demonstrated between the AxSYM 3rd Generation TSH assay and the AxSYM Ultrasensitive hTSH II assay. The Least Squares regression analysis between these two assays, using 921 specimens, yielded a Pearson correlation coefficient of 0.977, slope of 1.033 (95% confidence interval of 1.018, 1.047), and Y-axis intercept of 0.538 uIU/mL (95% confidence interval of 0.387, 0.690).

510(k) Summary Abbott AxSYM® 3rd Generation TSH
Summary of Safety and Effectiveness Information Supporting a Substantially Equivalent Determination
The following information as presented in the Premarket Notification [510(k)] for the Abbott AxSYM® 3rd Generation TSH constitutes data supporting a substantially equivalent determination.
AxSYM 3rd Generation TSH is a Microparticle Enzyme Immunoassay (MEIA) for the quantitative determination of TSH in human serum or plasma. AxSYM 3rd Generation TSH is calibrated with Abbott AxSYM 3rd Generation TSH Calibrators. Abbott AxSYM 3rd Generation TSH Controls are assayed for the verification of the accuracy and precision of the AxSYM System.
Substantial equivalence has been demonstrated between the AxSYM 3rd Generation TSH assay and the AxSYM Ultrasensitive hTSH II assay. The intended use of both assays is for the quantitative determination of TSH in human serum or plasma. Both assays are automated, in vitro immunoassays that use antibodies specific for TSH. The fluorescent signal measured by both assays is directly related to the concentration of TSH in the sample. The Least Squares regression analysis between these two assays, using 921 specimens, yielded a Pearson correlation coefficient of 0.977, slope of 1.033 (95% confidence interval of 1.018, 1.047), and Y-axis intercept of 0.538 uIU/mL (95% confidence interval of 0.387, 0.690).
In conclusion, these data demonstrate that the AxSYM 3rd Generation TSH assay is as safe and effective as, and is substantially equivalent to, the AxSYM Ultrasensitive hTSH II assay.
