No
The summary describes a standard in vitro diagnostic assay based on enzymatic reactions and spectrophotometric measurement, with no mention of AI or ML components.

No
This device is an in vitro diagnostic assay used for measuring enzyme activity for diagnostic purposes, not for treating a condition.

Yes

The "Intended Use / Indications for Use" section explicitly states that the assay is for "quantitative in vitro diagnostic determination" and that "Measurement of aspartate amino transferase levels aids in the diagnosis and treatment of certain types of liver and heart disease." This directly indicates its role in diagnosis.

No

The device description clearly outlines a chemical assay (reagents) and calibrators/controls for use on a specific hardware instrument (Hitachi 917). This is an in vitro diagnostic (IVD) test kit, not a software-only medical device.

Yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use/Indications for Use: The document explicitly states the assay is "intended for quantitative in vitro diagnostic determination of the activity of the enzyme aspartate amino transferase (AST) in human serum and lithium heparin plasma." It also mentions that the measurement "aids in the diagnosis and treatment of certain types of liver and heart disease." The phrase "For in vitro diagnostic use" is repeated multiple times.
  • Device Description: The description details the biochemical reaction used to measure the enzyme activity in a sample (human serum and plasma).
  • Performance Studies: The document includes performance data such as method comparison and precision, which are typical for IVD devices.
  • Predicate Device(s): The inclusion of predicate devices with K numbers (which are FDA clearance numbers for medical devices, including IVDs) further confirms its classification as an IVD.

All of these points align with the definition and characteristics of an In Vitro Diagnostic device, which is used to examine specimens from the human body to provide information for the diagnosis, prevention, or treatment of a disease or condition.

G. Substantial Equivalence

Similarities and Differences

The similarities and differences between the predicate and subject devices are provided below. Briefly, the ASAT assays, calibrators, and control material are similar with respect to intended use, functionality, and operating principle. Both assays are intended to operate as in viro quantitative tests for the measurement of ASAT (GOT) on the Hitachi 917 instrument. Both calibrators are intended to calibrate their respective ASAT assays. Both control materials are intended to monitor the accuracy and precision of their respective ASAT assays.

The main differences are that the subject assay device is indicated only for human serum and lithium heparin plasma while the predicate assay device is indicated for human serum and both EDTA and Heparin plasma, the subject callbrator is indicated only for ASAT on the Hitachi 917 instrument while the predicate calibrator is a multi-analyte calibrator that can be used on a variety of instruments, and the subject controls are indicated only for ASAT on the Hitachi 917 instrument while the predicate controls are multi-analyte controls that can be used on a variety of instruments.

Conclusion

In summary, the DiaSys Diagnostic Systems ASAT (GOT) FS assay, TruCal U calibrator, and TruLab N and TruLab P controls devices described in this 510(k) are, in our opinion, substantially equivalent to the predicate devices. They have the same intended use and technological characteristics as the predicates, and raise no new issues of safety or effectiveness.
