The description details a standard ELISA immunoassay, which relies on antibody-antigen binding and colorimetric detection, with no mention of AI or ML components.
No
This device is an in vitro diagnostic immunoassay for detecting Giardia antigen in feces, which is used for diagnosis, not for treating any condition.
Yes
Explanation: The device is an "in vitro immunoassay for the qualitative determination of Giardia antigen in feces," which indicates it is used to identify the presence of a specific substance (Giardia antigen) in a biological sample (feces) to diagnose a condition (Giardia infection).
No
The device description clearly outlines a laboratory-based immunoassay (ELISA) which involves physical reagents and a chemical reaction to detect an antigen. This is a hardware-based diagnostic test, not a software-only device.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The "Intended Use / Indications for Use" explicitly states that this ELISA is an "in vitro immunoassay for the qualitative determination of Giardia antigen in feces." The term "in vitro" means "in glass" or "outside the body," which is a key characteristic of IVDs.
- Sample Type: The device analyzes "feces," which is a biological sample taken from the human body.
- Purpose: The purpose is to "determine the presence of Giardia antigen," which is a diagnostic test performed on a biological sample to aid in the diagnosis of a condition (Giardia infection).
All of these points align with the definition of an In Vitro Diagnostic device.
N/A
Intended Use / Indications for Use
This ELISA is an in vitro immunoassay for the qualitative determination of Giardia antigen in feces. It is a double antibody (sandwich) ELISA using an anti-Giardia antibody to capture the antigen from the stool supernatant. A second antibody is then added which sandwiches the captured antigen. This reaction is visualized by the addition of an anti-second antibody conjugated to peroxidase and the chromogen tetramethylbenzidine (TMB). The resulting blue color development indicates the presence of Giardia antigens being bound by the anti-Giardia antibodies.

§ 866.3220
Entamoeba histolytica serological reagents.(a)
Identification. Entamoeba histolytica serological reagents are devices that consist of antigens and antisera used in serological tests to identify antibodies toEntamoeba histolytica in serum. Additionally, some of these reagents consist of antisera conjugated with a fluorescent dye (immunofluorescent reagents) used to identifyEntamoeba histolytica directly from clinical specimens. The identification aids in the diagnosis of amebiasis caused by the microscopic protozoan parasiteEntamoeba histolytica and provides epidemiological information on diseases caused by this parasite. The parasite may invade the skin, liver, intestines, lungs, and diaphragm, causing disease conditions such as indolent ulcers, an amebic hepatitis, amebic dysentery, and pulmonary lesions.(b)
Classification. Class II (special controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to § 866.9.

Trade/Device Name: Giardia Antigen Detection Microwell ELISA Assay Regulation Number: 21 CFR 866.3220 Regulation Name: Entamoeba histolytica serological reagents Regulatory Class: Class II Product Code: MHI Dated: August 19, 2002 Received: August 26, 2002
Dear Mr. Lambillotte:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and 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) that do not require approval of a premarket approval application (PMA). 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 (PMA), 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 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

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.
