Device Facts

• Record ID: K020467
• Device Name: SPIFE LD VIS ISOENZYME KIT, MODELS 3450, 3451, AND 3452
• Applicant: Helena Laboratories
• Product Code: CFE · Clinical Chemistry
• Decision Date: Mar 29, 2002
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 862.1445
• Device Class: Class 2

Intended Use

The SPIFE LD test system can be used in conjunction with CK isoenzyme studies to aid in the diagnosis of myocardial infarction. The LD1/LD2 "flip" can be present in patients after acute MI, severe anemias, renal necrosis and in-vivo or in-vitro hemolysis of any cause. The LD5 is increased in skeletal muscle injury or diseases, cirrhosis, hepatitis and passive liver congestion. Mid-zone fractions (LD2,3,4) are increased in cases of massive platelet destruction (pulmonary embolism) and in lymphatic system involvements such as mononucleosis, lymphomas and lymphocytic leukemias.

Device Story

SPIFE LD Vis Isoenzyme Kit is an in vitro diagnostic test system used for the separation and quantification of lactate dehydrogenase (LD) isoenzymes. The device utilizes electrophoresis to separate LD isoenzymes in serum samples. Following separation, the isoenzymes are visualized and quantified to identify specific patterns associated with clinical conditions such as myocardial infarction, liver disease, or muscle injury. The system is intended for use in clinical laboratory settings by trained laboratory personnel. Results are interpreted by clinicians to assist in the diagnosis and management of the aforementioned conditions. The device provides objective data on isoenzyme distribution, aiding in differential diagnosis.

Clinical Evidence

No clinical data provided; substantial equivalence is based on bench testing and performance characteristics of the electrophoresis test system.

Technological Characteristics

Electrophoresis-based in vitro diagnostic test system for LD isoenzyme separation. Utilizes chemical reagents and gel media for separation and visualization. Designed for use with the SPIFE electrophoresis system. Class II device, product code CFE.

Indications for Use

Indicated for use in conjunction with CK isoenzyme studies to aid in the diagnosis of myocardial infarction. Applicable to patients with suspected acute MI, severe anemias, renal necrosis, hemolysis, skeletal muscle injury/disease, liver conditions (cirrhosis, hepatitis, congestion), pulmonary embolism, or lymphatic system involvement (mononucleosis, lymphomas, leukemias).

Regulatory Classification

Identification

A lactate dehydrogenase isoenzymes test system is a device intended to measure the activity of lactate dehydrogenase isoenzymes (a group of enzymes with similar biological activity) in serum. Measurements of lactate dehydrogenase isoenzymes are used in the diagnosis and treatment of liver diseases, such as viral hepatitis, and myocardial infarction.

Special Controls

*Classification.* Class II (special controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 862.9.

Dear Ms. Frank:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and 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) that do not require approval of a premarket approval application (PMA). 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. Iisting 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 (PMA), 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 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
