No
The description details a standard clinical chemistry assay based on a chemical reaction and absorbance measurement, with no mention of AI or ML terms or concepts.
No
The device is an in vitro diagnostic assay used for the quantitative determination of direct bilirubin in human serum or plasma to aid in the diagnosis and treatment of disorders. It does not directly treat or restore function.
Yes
The "Intended Use / Indications for Use" section explicitly states that the measurement of bilirubin is "used in the diagnosis and treatment of liver, hemolytic hematological, and metabolic disorders." This directly indicates its role as a diagnostic device.
No
The device description clearly states it is an "in vitro diagnostic assay" and describes a chemical reaction and measurement of absorbance, indicating it is a physical assay kit, not software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The "Intended Use / Indications for Use" section explicitly states that the assay is used for the quantitation of direct bilirubin in human serum or plasma. This indicates it's used to test human specimens.
- Device Description: The "Device Description" section clearly states that the Direct Bilirubin is an in vitro diagnostic assay for the quantitative determination of direct bilirubin in human serum or plasma. The term "in vitro diagnostic" is used directly.
- Method of Analysis: The description of how the assay works (oxidizing conjugated bilirubin and measuring the decrease in absorbance) is a typical method used in laboratory testing of biological samples.
- Performance Studies: The performance studies describe testing the assay's performance using control materials and comparing it to a predicate device, which is standard practice for validating IVDs.
All of these points strongly indicate that this device is designed to be used outside of the body to examine specimens from the human body for diagnostic purposes, which is the definition of an In Vitro Diagnostic device.

Intended Use / Indications for Use
The Direct Bilirubin assay is used for the quantitation of direct bilirubin in human serum or plasma. Measurement of bilirubin, an organic compound formed during the normal and abnormal destruction of red blood cells, is used in the diagnosis and treatment of liver, hemolytic hematological, and metabolic disorders, including hepatitis and gall bladder block.

Device Description
Direct Bilirubin is an in vitro diagnostic assay for the quantitative determination of direct bilirubin in human serum or plasma. The Direct Bilirubin assay is a clinical chemistry assay in which the conjugated bilirubin is oxidized to biliverdin. The resulting decrease in absorbance at 444 nm is directly proportional to the concentration of direct bilirubin.

Summary of Performance Studies
Comparative performance studies were conducted using the AEROSET™ System. The Direct Bilirubin assay method comparison yielded acceptable correlation with the Wako Diagnostics Direct Bilirubin assay on the Hitachi 717 Analyzer. The correlation coefficient = 0.9878, slope = 1.168, and Y-intercept = 0.081 mg/dL. Precision studies were conducted using the Direct Bilirubin assay. Within-run, between-run, and between-day studies were performed using two levels of control material. The total %CV for Level 1/Panel 101 is 4.0% and Level 2/Panel 102 is 3.8%. The Direct Bilirubin assay is linear up to 50.2 mg/dL. The limit of quantitation (sensitivity) for the Direct Bilirubin assay is 0.11 mg/dL. These data demonstrate that the performance of the Direct Bilirubin assay is substantially equivalent to the performance of the Wako Diagnostics Direct Bilirubin assay on the Hitachi 717 Analyzer.

Dear Mr. Littlefield:
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 reqistration, 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 requlations 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 requirement, 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.
