The K-ASSAY Transferrin Assay is intended to be used for the quantitative determination of Transferrin in human serum by immunoturbidimetric assay. Measurement of transferrin levels aids in the diagnosis of malnutrition, acute inflammation, infection, and red blood cell disorders, such as iron deficiency anemia. FOR IN VITRO DIAGNOSTIC USE.
Device Story
K-ASSAY Transferrin is an in vitro diagnostic reagent for quantitative measurement of transferrin in human serum. Operates via immunoturbidimetric assay principle; utilizes antigen-antibody reaction to produce turbidity proportional to transferrin concentration. Used in clinical laboratory settings by trained laboratory personnel. Output is a quantitative concentration value used by clinicians to assess nutritional status, inflammation, infection, or anemia. Results assist in clinical decision-making regarding patient diagnosis and management.
Clinical Evidence
No clinical data provided; device relies on analytical performance characteristics typical of immunoturbidimetric assays.
Technological Characteristics
Immunoturbidimetric assay; liquid reagent format; intended for use on automated clinical chemistry analyzers. Measures light absorbance changes resulting from antigen-antibody complex formation.
Indications for Use
Indicated for quantitative determination of Transferrin in human serum to aid in diagnosis of malnutrition, acute inflammation, infection, and red blood cell disorders (e.g., iron deficiency anemia). For in vitro diagnostic use.
Regulatory Classification
Identification
A transferrin immunological test system is a device that consists of the reagents used to measure by immunochemical techniques the transferrin (an iron-binding and transporting serum protein) in serum, plasma, and other body fluids. Measurement of transferrin levels aids in the diagnosis of malnutrition, acute inflammation, infection, and red blood cell disorders, such as iron deficiency anemia.

Dear Mr. Getty:
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.

Under the Clinical Laboratory Improvement Amendments of 1988 (CLIA-88), this device may require a CLIA complexity categorization. To determine if it does, you should contact the Centers for Disease Control and Prevention (CDC) at (770)488-7655.
This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at (301) 594-4588. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97).
