Indications for Use

Cell cultures to be used as hosts for the isolation and identification of specific viruses. The subject of this 510(k) Notification, the cell lines HEL, HFF, LLC-MK2, MvlLu, NCI H292, Vero and WI-38 are susceptible to and can be used in the isolation and confirmation of the following viruses from clinical samples: [Table of cell lines and viruses omitted for brevity]. FreshCella™ are indicated for use in the isolation of Viruses and Chlamydia various viruses and Chlamydia from clinical specimens. 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.

Device Story

FreshCells™ are cultured animal and human cell lines (HEL, HFF, LLC-MK2, Mv1Lu, NCI H292, Vero, WI-38) provided as nearly confluent monolayers in multiwell plates, shell vials, or tubes. Used in clinical laboratory settings by laboratory technicians to isolate and identify specific viruses and Chlamydia from patient clinical samples. The cells serve as host substrates for viral replication. Healthcare providers use the resulting viral identification to guide clinical decision-making, particularly for selecting appropriate antiviral therapies. The device benefits patients by enabling accurate diagnosis of viral infections, which is critical for managing potentially lethal infections in immunocompromised populations.

Clinical Evidence

No clinical data. Evidence consists of non-clinical bench testing to characterize product appearance, growth characteristics, sterility, isoenzyme analysis, and virus susceptibility.

Technological Characteristics

Cell lines (HEL, HFF, LLC-MK2, Mv1Lu, NCI H292, Vero, WI-38) provided as nearly confluent monolayers in multiwell plates, shell vials, or tubes. Biological substrate for viral isolation. No software or electronic components.

Indications for Use

Indicated for the isolation and identification of viruses and Chlamydia from clinical specimens in patients, including immunocompromised individuals, where viral agent identification is required for clinical management.

Regulatory Classification

Identification

Cultured animal and human cells are in vitro cultivated cell lines from the tissue of humans or other animals which are used in various diagnostic procedures, particularly diagnostic virology and cytogenetic studies.

Predicate Devices

• BioWhittaker cell cultures (Appendix II)

Dear Mr. Brown:

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 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.
