Intended Use

Architect Free T4 MasterCheck is intended for use in the verification of sensitivity, calibration linearity, and reportable range on the Abbott Architect i System

Device Story

Architect Free T4 MasterCheck is a multi-level human serum-based control product used in clinical laboratory settings. It contains Free T4 (levels 1-3) and a preservative (sodium azide). The device is used by laboratory technicians to verify the performance of the Abbott Architect i System, specifically for sensitivity, calibration linearity, and reportable range. By running these samples, the user compares the system's output against expected values to ensure the assay is performing within specifications. This verification process supports clinical decision-making by ensuring the accuracy and reliability of patient Free T4 test results.

Clinical Evidence

No clinical data; bench testing only.

Technological Characteristics

Liquid human serum matrix containing Free T4 and sodium azide preservative. Designed for use with the Abbott Architect i System. Storage at 2-8°C.

Indications for Use

Indicated for use as a calibration verification material for the Abbott Architect i System to verify sensitivity, calibration linearity, and reportable range of the Free T4 assay.

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 Regulation (QS) for Medical Devices: General regulation (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.
