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.

No
The summary describes a laboratory test system for analyzing enzyme levels, with no mention of AI or ML technologies.

No
The device aids in diagnosis by measuring LD isoenzymes, which is a diagnostic function, not a therapeutic one.

Yes
The document explicitly states that the device "can be used in conjunction with CK isoenzyme studies to aid in the diagnosis of myocardial infarction."

No

The 510(k) summary describes a "test system" and mentions "CK isoenzyme studies," which strongly implies a laboratory-based system involving physical reagents, instruments, and sample processing, not solely software. The lack of a device description further supports this interpretation as it doesn't provide any information to suggest it's a software-only device.

Based on the provided information, the SPIFE LD test system is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly states that the system is used "in conjunction with CK isoenzyme studies to aid in the diagnosis of myocardial infarction." This involves analyzing biological samples (likely blood or serum, although not explicitly stated) to provide information about a patient's health status and aid in diagnosis.
  • LD Isoenzyme Analysis: The description of the different LD fractions (LD1/LD2, LD5, mid-zone fractions) and their association with various medical conditions (myocardial infarction, anemias, liver diseases, etc.) indicates that the device is performing a laboratory test on biological samples.

IVD devices are defined as reagents, instruments, and systems intended for use in the diagnosis of disease or other conditions, including a determination of the state of health, in order to cure, mitigate, treat, or prevent disease or its sequelae. The SPIFE LD test system fits this description by analyzing biological markers (LD isoenzymes) to aid in diagnosis.

§ 862.1445 Lactate dehydrogenase isoenzymes test system.

(a)
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.(b)
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.
