The summary describes a standard immunoassay and analyzer, with no mention of AI or ML in the intended use, device description, or specific sections for AI/ML details.
No.
The device is an immunoassay system used for quantitative determination of total beta-human chorionic gonadotropin, aiding in the early detection of pregnancy, and is not designed to treat or cure a condition.
Yes
The device is intended for the quantitative determination of total beta-human chorionic gonadotropin (total BhCG) in human serum, which is used as an aid in the early detection of pregnancy. This constitutes a diagnostic purpose.
No
The device description explicitly mentions a "Chemiluminescence Immunoassay Analyzer," which is a hardware component. The assay itself is a reagent, also not software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states it's for the "quantitative determination of total beta-human chorionic gonadotropin (total BhCG) in human serum". This involves testing a sample taken from the human body (serum) in vitro (outside the body).
- Method: It uses a "chemiluminescent immunoassay", which is a common method for in vitro diagnostic testing.
- Purpose: The assay is intended "for use as an aid in the early detection of pregnancy", which is a diagnostic purpose.
- Analyzer: The description mentions the "Diazyme DZ-Lite iFlash 1800 Chemiluminiscence Immunoassay Analyzer" which is used for "determination of analytes in human body fluids through acridinium ester-based chemiluminescence method". This further confirms the in vitro nature of the testing.

(a)
Human chorionic gonadotropin (HCG) test system intended for the early detection of pregnancy —(1)Identification. A human chorionic gonadotropin (HCG) test system is a device intended for the early detection of pregnancy is intended to measure HCG, a placental hormone, in plasma or urine.(2)
Classification. Class II.(b)
Human chorionic gonadotropin (HCG) test system intended for any uses other than early detection of pregnancy —(1)Identification. A human chorionic goadotropin (HCG) test system is a device intended for any uses other than early detection of pregnancy (such as an aid in the diagnosis, prognosis, and management of treatment of persons with certain tumors or carcinomas) is intended to measure HCG, a placental hormone, in plasma or urine.(2)
Classification. Class III.(3)
Date PMA or notice of completion of a PDP is required. As of the enactment date of the amendments, May 28, 1976, an approval under section 515 of the act is required before the device described in paragraph (b)(1) may be commercially distributed. See § 862.3.

Dear Chao Dou:
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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies.combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.
