The description details a standard enzymatic colorimetric assay, which is a biochemical method, and there is no mention of AI or ML in the intended use, device description, or specific sections for AI/ML information.
No
The device is a screening assay used for diagnosis, not for treating a condition.
No
The device is described as a screening assay, and the text explicitly states, "Elevated results are not diagnostic per se of galactosaemia." It indicates the need for "further study" for positive results, implying it does not provide a definitive diagnosis.
No
The device description clearly states it is an "enzymatic colorimetric end-point method," which involves chemical reagents and laboratory procedures, indicating it is a physical assay kit, not software.
Based on the provided information, the Quantase Total Galactose Screening Assay is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states it's for the determination of total D(+)galactose in dried blood spot specimens from newborn human infants as part of a newborn screening programme. This involves testing a sample taken from the body (in vitro) to provide information about a physiological state (galactose levels).
- Device Description: The description confirms it's an enzymatic colorimetric method for analyzing a biological sample (dried blood spot specimens).
- Anatomical Site: It specifies "dried blood spot specimens," which are samples taken from the body.
The definition of an IVD generally includes reagents, instruments, and systems intended for use in the diagnosis of disease or other conditions, including a determination of the state of health, in order to cure, mitigate, treat, or prevent disease or its sequelae. This device fits that description as it's used to screen for elevated galactose levels, which can indicate a potential condition (galactosaemia).
N/A
Intended Use / Indications for Use
The Quantase Total Galactose Screening Assay is an enzymatic colorimetric end-point method for the determination of total D(+)galactose (D(+)galactose + galactose-1-phosphate) in dried blood spot specimens taken from newborn human infants as part of a newborn screening programme.
The test is intended as a screening the total D(+)galactose concentrations in newborn blood spot specimens. Elevated results are not diagnostic per se of galactosaemia, but indicate the urgent need for further study of the newborn from which the presumptive positive specimen was received.
The kit is NOT intended for use in monitoring the circulating concentrations of total D(+)galactose in galactosaemic patients nor to detect ante-natal galactosaemia.

Dear Dr. Campbell:
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 vou 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).
