Neometrics' ACCUWELL™ Phenylalanine kits are intended to be used for the quantitative measurement of phenylalanine in neonatal dried blood spot samples which have been collected onto S&S grade 903 filter paper. Results are used to screen for phenylketonuria disease.
Not Found
I am sorry, but based on the provided document, I cannot answer questions 1-9. The document is a 510(k) clearance letter from the FDA for the ACCUWELL™ Phenylalanine device, dated December 5, 1997. It primarily discusses the regulatory approval and classification of the device.
The letter explicitly states that the FDA "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 devices marketed in interstate commerce prior to May 28, 1976..."
This type of document does not contain specific details about:
- Detailed acceptance criteria and reported device performance (beyond the general statement of substantial equivalence).
- Sample sizes used for test sets, data provenance, number of experts for ground truth, adjudication methods, MRMC studies, standalone performance, or types of ground truth used in testing that informed the substantial equivalence.
- Training set details (sample size, ground truth establishment methods).
These details would typically be found in the 510(k) submission itself, which is not provided in this excerpt. The included "Statement of Indications for Use" only describes what the device is intended for.
