Intended Use
The ARCHITECT™ Total T (TT ) assay is a Chemiluminescent Microparticle Immunoassay (CMIA) for the quantitative determination of thyroxine (total T.) in human serum and plasma. The ARCHITECT Total T assay is to be used as an aid in the assessment of thyroid status.
Device Story
ARCHITECT Total T4 is a Chemiluminescent Microparticle Immunoassay (CMIA) used for quantitative measurement of total thyroxine in human serum or plasma (lithium heparin, sodium heparin, or potassium EDTA). The assay is performed on the Abbott ARCHITECT i System. It is intended for use by clinical laboratory professionals to aid in the assessment of thyroid status. The system processes patient samples, performs the immunoassay, and provides quantitative results to the clinician to support diagnostic decision-making regarding thyroid function.
Clinical Evidence
Bench testing only. Comparative study of 1155 human serum/plasma specimens between ARCHITECT Total T4 and AxSYM Total T4. Results showed a correlation coefficient of 0.928. Least squares regression: slope 1.01, intercept -0.11 ug/dL. Passing-Bablok regression: slope 0.99, intercept -0.13 ug/dL.
Technological Characteristics
Chemiluminescent Microparticle Immunoassay (CMIA) technology. Designed for use on the Abbott ARCHITECT i System. Analyte: total thyroxine (T4). Sample types: human serum, lithium heparin plasma, sodium heparin plasma, potassium EDTA plasma.
Indications for Use
Indicated for the quantitative determination of total thyroxine (T4) in human serum and plasma to aid in the assessment of thyroid status.
Regulatory Classification
Identification
A total thyroxine test system is a device intended to measure total (free and protein bound) thyroxine (thyroid hormone) in serum and plasma. Measurements obtained by this device are used in the diagnosis and treatment of thyroid diseases.
Special Controls
*Classification.* Class II (special controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 862.9.

## 510(k) Summary Abbott ARCHITECT™ Total Ta
## Summary of Safety and Effectiveness Information Supporting a Substantially Equivalent Determination
The following information as presented in the Premarket Notification [510(k)] for Abbott ARCHITECT™ Total T, constitutes data supporting a substantially equivalent determination.
ARCHITECT Total T, is a Chemiluminescent Microparticle Immunoassay (CMIA) for the quantitative determination of total T , in human serum or plasma (lithium heparin, sodium heparin. or potassium EDTA). ARCHITECT Total T, is calibrated with ARCHITECT Total T, Calibrators. ARCHITECT Total T, Controls are assayed for the verification of the accuracy and precision of the Abbott ARCHITECT i System.
Substantial equivalence has been demonstrated between the ARCHITECT Total T. assay and the AxSYM® Total T. assay. The intended use of both assays is for the quantitative determination of total T. in human serum and plasma. Least squares linear regression analysis of an ARCHITECT Total T. vs. AxSYM Total T. comparison, using 1155 specimens, gave the following parameter estimates: correlation coefficient = 0.928. slope = 1.01 and y-axis intercept = - 0.11 ug/dL. Passing-Bablok linear regression analysis of an ARCHITECT Total T, vs. AxSYM Total T, comparison, using 1155 specimens, gave the following parameter estimates: correlation coefficient = 0.928, slope = 0.99 and yaxis intercept = - 0.13 ug/dL.
In conclusion, these data demonstrate that the ARCHITECT Total T2 assay is as safe and effective as, and is substantially equivalent to, the AxSYM Total Ta assay.

Dear Ms. Veoukas:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Requlations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General requlation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
