The description details a standard immunochromatographic assay for drug screening, with no mention of AI or ML in the intended use, device description, or performance studies.
No
Explanation: The device is an in vitro diagnostic test designed to screen for the presence of a cocaine metabolite in human urine, providing only a preliminary analytical result. It does not treat or diagnose a disease, which are characteristics of a therapeutic device.
Yes
Explanation: The device is used to screen human urine for the presence of a cocaine metabolite, providing a preliminary analytical result which indicates a diagnostic purpose.
No
The device description clearly states it is an "immunochromatographic based one step in vitro test," which is a physical test kit, not software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states it is used to "screen human urine for the presence of the cocaine metabolite, benzoylecgonine". This involves testing a biological sample (urine) outside of the body to gain information about a person's health status (presence of a drug metabolite).
- Device Description: The device description clearly states it is an "immunochromatographic based one step in vitro test". "In vitro" directly means "in glass" or "outside of the body", which is the core characteristic of an IVD.
The information provided strongly indicates that this device is designed to perform diagnostic testing on a biological sample in a laboratory or similar setting, which aligns with the definition of an In Vitro Diagnostic device.
N/A
Intended Use / Indications for Use
The Redi-Test Cocaine is a qualitative, one step immunochromatographic competitive assay used to screen human urine for the presence of the cocaine metabolite, benzoylecgonine at a cutoff concentration of 300ng/mL. The test is qualitative and provides only a preliminary analytical result, which must be confirmed by an alternate methodology preferably, GC/MS.

§ 862.3250 Cocaine and cocaine metabolite test system.
(a)
Identification. A cocaine and cocaine metabolite test system is a device intended to measure cocaine and a cocaine metabolite (benzoylecgonine) in serum, plasma, and urine. Measurements obtained by this device are used in the diagnosis and treatment of cocaine use or overdose.(b)
Classification. Class II (special controls). A cocaine and cocaine metabolite 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).

Device Classification: Class II, 862.3250, Panel 91 Toxicology
-
Device description: The Redi-Test Cocaine is an immunochromatograpic based one step in vitro test.
-
Intended Use: The Redi-Test Cocaine is a qualitative, one step immunochromatographic competitive assay used to screen human urine for the presence of the cocaine metabolite, benzoylecgonine at a cutoff concentration of 300ng/mL. The test is qualitative and provides only a preliminary analytical result, which must be confirmed by an alternate methodology preferably, GC/MS.
-
Substantial Equivalence: The Redi-Test Cocaine was found substantially equivalent to the DRI. Cocaine Enzyme Immunoassay. Both products are immunoassays and use specific antibodies to detect the major metabolite of cocaine, benzoylecgonine. Both assays are preliminary screens for human urine and require confirmation with alternate methods such as GC/MS. The sensitivity of the tests are similar, the DRI and Redi-Test both detect benzoylecgonine at a cut off of 300ng/mL. The tests demonstrated 99% correlation when 100 specimens (50 negative and 50 positive over the entire assay range) were compared. The tests are similar in sensitivity, specificity, accuracy and precision.
Conclusion:
The Cocaine Enzyme Immunoassay and the Redi-Test Cocaine are substantially equivalent in performance characteristics. The correlation of the two tests was 99%,

Dear Ms. Freestone:
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 (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.
