The description details a standard lateral flow immunoassay for detecting hCG in urine, with no mention of AI, ML, image processing, or any computational analysis beyond a simple chemical reaction and visual interpretation.
No
A therapeutic device intends to treat or mitigate a disease or condition. This device is for detection/diagnosis only, not for treatment.
Yes
The device determines the qualitative presence of human chorionic gonadotropin (hCG) in urine for the early detection of pregnancy, which is a diagnostic purpose.
No
The device description clearly indicates a physical test for detecting hCG in urine, which 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 explicitly states it's for the "qualitative determination of human chorionic gonadotropin (hCG) in urine". This involves testing a biological sample (urine) outside of the body (in vitro).
- Device Description: The description further clarifies that it's used for "detecting human Chorionic Gonadotropin (hCG) in urine". This reinforces the in vitro nature of the test.
- Mechanism: The test works by detecting a specific substance (hCG) in a biological sample (urine) to provide diagnostic information (early detection of pregnancy). This is the core function of an IVD.
The fact that it's for Over-The-Counter Use and intended for untrained individuals doesn't change its classification as an IVD. IVDs can be designed for various user types and settings.

Device Description
The One-Step Pregnancy Test is to be used for detecting human Chorionic Gonadotropin (hCG) in urine. The presence of hCG usually appears about the seventh day after fertilization. The One-Step Pregnancy Test will detect hCG in urine at a concentration level of 25 mIU/ml. The One-Step Pregnancy Test will be sold for under private label in the Over-the-Counter Market. The One-Step Pregnancy Test employs a unique combination of monoclonal-dye conjugate and polyclonal-solid phase antibodies to selectively identify human Chorionic Gonadotropin (hCG) in urine. As the urine sample flows through the absorbent portion of the device, the antibody-dye conjugate binds to the hCG forming an antibody-antigen complex. This complex binds to the anti-hCG antibody in the positive reaction zone and produces a pink-rose color band if hCG concentration is equal to or greater than 25 mIU/ml. In the absence of hCG, there is no line in the reaction zone. Unbound conjugate binds to the reagents in the control zone, producing a pink-rose color band, demonstrating that the reagents are functioning correctly.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
A clinical trial was done to compare the performance of the One-Step Pregnancy Test to a FDA cleared product. These data clearly demonstrate the performance of the One-Step Pregnancy Test by Amerisource is substantially equivalent to a commercially available FDA cleared pregnancy test: Stanbio True 20 One-Step Pregnancy Test. The One-Step Pregnancy Test when compared with another commonly used pregnancy test (Stanbio True) demonstrated 100% performance. All pregnancy results were confirmed by physical examination and/or ultrasound.
