No
The device description details a lateral flow immunochromatographic assay, which is a chemical reaction-based test, not a software or algorithm-based technology. There is no mention of AI, ML, image processing, or any computational analysis of the results. The interpretation is based on the presence or absence of a colored line.
No
The device is a diagnostic tool for detecting tricyclic antidepressants in urine, not a device used for therapy.
Yes
The device qualitatively detects Tricyclic Antidepressants in human urine, which provides information for the diagnosis or monitoring of a medical condition.
No
The device is a rapid chromatographic immunoassay test strip/device, which is a physical hardware component used for qualitative detection of substances in urine. It does not describe any software component.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states it's for the "qualitative detection of Tricyclic Antidepressants in human urine." This is a diagnostic test performed on a sample taken from the human body.
- Device Description: The description details a "rapid chromatographic immunoassay" and a "competitive binding, lateral flow immunochromatographic assay" that utilizes antibodies to detect a substance in a urine sample. These are common characteristics of IVD devices.
- Sample Type: The test is performed on "human urine," which is a biological specimen.
- Purpose: The purpose is to detect the presence of Tricyclic Antidepressants, which is a diagnostic function related to identifying a substance in the body.
- Performance Studies: The document includes performance studies comparing the device to a predicate device and a reference method (HPLC), which are typical requirements for demonstrating the performance of an IVD.
Therefore, based on the provided information, the ACON TCA One Step Tricyclic Antidepressants Test Strip and Test Device clearly fit the definition of an In Vitro Diagnostic device.

Device Description
The ACON TCA One Step Tricyclic Antidepressant Test Strip and ACON TCA One Step Tricyclic Antidepressant Test Device are competitive binding, lateral flow immunochromatographic assays for the qualitative screening of Tricyclic Antidepressant in a urine sample. The test is based on the principle of antigen-antibody immuncchemistry. It utilizes mouse monoclonal antibody to selectively detect elevated levels of Tricyclic Antidepressant in urine at a cut-off concentration of 1000 ng/mL for Nortriptyline. These tests can be performed without the use of an instrument.
A drug-positive urine specimen will not generate a colored-line in the designated test region, while a negative urine specimen or a urine specimen containing Tricyclic Antidepressant at the concentration below the cut-off level will generate a colored-line in the test region. To serve as a procedural control. a colored-line will always appear at the control region, indicating that proper volume of specimen has been added and membrane wicking has occurred.

A clinical evaluation was conducted using 226 clinical urine specimens including over 10% of the samples with Antidepressants concentrations at -25% cut-off to +25% cut-off range. This evauation compared the test results between ACON® TCA One Step Tricyclic Antidepressants Test Strip and Test Device with Status DS™ One Step Tricyclic Antidepressants Test; as well as against data obtained from the customary HPLC analysis.
Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
A clinical evaluation was conducted using 226 clinical urine specimens including over 10% of the samples with Antidepressants concentrations at -25% cut-off to +25% cut-off range. This evauation compared the test results between ACON® TCA One Step Tricyclic Antidepressants Test Strip and Test Device with Status DS™ One Step Tricyclic Antidepressants Test; as well as against data obtained from the customary HPLC analysis. The comparisons of data obtained from this study yielded the following results:
ACON TCA One Step Tricyclic Antidepressant Test Strip versus the Status DSTM One Step Tricyclic Antidepressants Test:
Positive Agreement: 55 / 58 = 95% (86% - 99%) Negative Agreement: 164 / 164 = 100% (98% - 99%) Overall Agreement: 219 / 222 = 99% (96% - 99 %*) * 95% Confidence Intervals

ACON TCA One Step Tricyclic Antidepressant Test Strip versus HPLC at the cutoff of 1,000 ng/ml:
Negative agreement: 89% (84% - 93%)*
Positive agreement: >99% (90% - 99%)*

Negative agreement: 89% (84% - 93%)*
Positive agreement: >99% (90% - 99%)*
These clinical studies demonstrate the substantial equivalency between the ACON TCA One Step Tricyclic Antidepressant Test Strip, ACON TCA One Step Tricyclic Antidepressant Test Device and the Status DSTM One Step Tricyclic Antidepressant Test, which has already being marketed in the United States. It is also demonstrated that these tests are safe and effective in detecting Tricyclic Antidepressant at a concentration of 1,000 ng/mL. The POL study demonstrated that these tests are suitable for healthcare professionals including professionals at point-of-care site.

§ 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).
