Intended Use

Architect Total T3 MasterCheck is intended for use in the verification of sensitivity, calibration linearity, and reportable range of the Total T3 assay on the Abbott Architect i System.

Device Story

Architect Total T3 MasterCheck is a multi-level liquid control product containing human serum and Total T3 (except Level 0). It is used in clinical laboratory settings to verify the performance of the Total T3 assay on the Abbott Architect i System. The device serves as a calibration verifier, allowing laboratory technicians to assess the sensitivity, calibration linearity, and reportable range of the assay. By comparing the measured values of the MasterCheck levels against expected ranges, the healthcare provider ensures the accuracy and reliability of patient test results. This verification process helps maintain the quality of diagnostic testing, ultimately benefiting patients by ensuring that thyroid hormone measurements are precise and clinically actionable.

Clinical Evidence

No clinical data. Bench testing only.

Technological Characteristics

Liquid control material; matrix is human serum; contains sodium azide as a preservative. Levels 1-3 contain Total T3. Storage at 2-8°C. Standalone diagnostic control product.

Indications for Use

Indicated for use as a calibration verification material for the Total T3 assay on the Abbott Architect i System to verify sensitivity, calibration linearity, and reportable range. No specific patient population is described as this is an in vitro diagnostic control product.

Regulatory Classification

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.

Dear Ms. Platt:

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 Regulations, 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 Requlation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Druq 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.
