## Indications for Use

CryovCheck™ LA Sure™ dilute Russell's Viper Venom Test (dRVVT) is a high concentration phospholipid reagent intended for use in a confirmatory test to verify the presence of lupus anticoagulants (LA) in human plasma. Once LA is suspected by a prolonged result with the Cryov Check™ LA Check™ screening (low concentration phospholipid) reagent, LA Sure may then be used concomitantly to establish a ratio (LA Check/LA Sure) useful in discriminating between LA positive and LA negative specimens.

## Device Story

Cryo Check™ LA Sure™ is a high-concentration phospholipid reagent used in clinical laboratories for coagulation testing. It functions as a confirmatory test for lupus anticoagulants (LA) in human plasma. The device is used in conjunction with a screening reagent (LA Check™). By comparing results from the low-phospholipid screening test and the high-phospholipid confirmatory test (LA Sure™), clinicians calculate a ratio to discriminate between LA-positive and LA-negative specimens. This aids in the diagnosis of patients suspected of having lupus anticoagulants, which are associated with thrombotic disorders.

## Technological Characteristics

In vitro diagnostic reagent; high-concentration phospholipid formulation; dilute Russell's Viper Venom Test (dRVVT) methodology; intended for use in clinical laboratory settings.

## Regulatory Identification

Russell viper venom reagent is a device used to determine the cause of an increase in the prothrombin time.

Dear Mr. Morrison:

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). Other general information on your responsibilities under the Act may be obtained from the Division of Small Manufacturers Assistance at its toll-free number (800) 638-2041 or (301) 443-6597, or at its internet address "http://www.fda.gov/cdrh/dsma/dsmamain.html".
