FreshCells™ are indicated for use in the isolation of various viruses and Chlamydia from clinical specimens. Viruses and Chlamydia are intracellular parasites which can be cultured or grown only in specific cellular hosts. They cause a variety of diseases in man with some virus infections being lethal, particularly if the individual is immunocompromised. With the introduction of several new and specific antiviral drugs over the last several years, the need to determine the identity of the viral agent has become even more important. Culture of viruses in specific cell lines has become the standard for the identification of these viruses.
The subject device provides HEL, HFF, LLC-MK2, MVILu, NCI H292, Vero and WI-38 cells (in addition to MRC-5, McCOY, BGMK, and CV-1, under 510 (k) K936271 and A549 and HEp-2, under 510(k) K962306 which have previously been cleared for marketing under the same name, Fresh Cella™) as nearly confluent monolayers ready for use upon receipt after a short pre-incubation period.
The provided text describes the 510(k) submission for "FreshCells™" cell cultures, intended for the isolation and identification of specific viruses. This submission is for a biological product (cell cultures used in diagnostic tests), not an AI/ML powered device. As such, the requested information regarding acceptance criteria for an AI device, sample sizes, expert qualifications, adjudication methods, MRMC studies, standalone performance, training sets, and ground truth establishment is not applicable to this document.
The document primarily focuses on demonstrating substantial equivalence to a predicate device based on:
- Technological Characteristics Comparison: Showing that the source of the cell line, the format (nearly confluent monolayers), and the intended use are the same as the predicate device.
- Non-Clinical Tests: Characterizing the product based on appearance, growth characteristics, sterility, isoenzyme analysis, and virus susceptibility.
Essentially, the "device" here is a biological reagent (cell cultures), and the evaluation is about its quality and suitability for its intended biological diagnostic purpose, not about the performance of an algorithm.
