The description focuses on a standard enzyme immunoassay for drug detection, with no mention of AI or ML terms or functionalities.
No
The device is an immunoassay kit used for qualitative and semiquantitative determination of tricyclic antidepressants, assisting in diagnosis, not directly treating a condition.
Yes
The text states that the device "can assist the physician in diagnosis and determination of steps towards treatment." This indicates its role in the diagnostic process.
No
The device description clearly states it is an "enzyme immunoassay," which is a laboratory test involving chemical reactions and physical components, not solely software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states it's for the "qualitative and semiquantitative determination of tricyclic antidepressants in serum, plasma or urine of patients suspected of drug overdose." This involves testing biological samples (serum, plasma, urine) outside of the body to provide information for diagnosis and treatment.
- Device Description: The description "homogeneous tricyclics serum tox enzyme immunoassay" further confirms it's a laboratory test designed to analyze biological samples.
These are key characteristics of an In Vitro Diagnostic device.
N/A
Intended Use / Indications for Use
This homogeneous tricyclics serum tox enzyme immunoassay is intended to be used for qualitative and semiquantitative determination of tricyclic antidepressants in serum, plasma or urine of patients suspected of drug overdose. A 300 ng/mL nortriptyline cutoff calibrator is used in this assay to differentiate a positive from a negative sample. Detection of the drug presence and its approximate concentration in serum, plasma or urine from patients suspected of drug overdose can assist the physician in diagnosis and determination of steps towards treatment.

§ 862.3910 Tricyclic antidepressant drugs test system.
(a)
Identification. A tricyclic antidepressant drugs test system is a device intended to measure any of the tricyclic antidepressant drugs in serum. The tricyclic antidepressant drugs include imipramine, desipramine, amitriptyline, nortriptyline, protriptyline, and doxepin. Measurements obtained by this device are used in the diagnosis and treatment of chronic depression to ensure appropriate therapy.(b)
Classification. Class II (special controls). A tricyclic antidepressant drugs test system is not exempt if it is intended for any use other than employment or insurance testing or is intended for Federal drug testing programs. 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, provided the test system is intended for employment and insurance testing and includes a statement in the labeling that the device is intended solely for use in employment and insurance testing, and does not include devices intended for Federal drug testing programs (e.g., programs run by the Substance Abuse and Mental Health Services Administration (SAMHSA), the Department of Transportation (DOT), and the U.S. military).

Dear Mr. Tsay:
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 (OS) 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 at (301) 443-6597 or at its internet address "http://www.fda.gov/cdrh/dsmamain.html"
