The device description details a traditional lateral flow immunoassay based on antibody reactions and visual interpretation of colored lines. There is no mention of any computational analysis, algorithms, or learning processes.
No
Explanation: This device is a diagnostic tool used to detect pregnancy, not to treat or alleviate a medical condition.
Yes
Explanation: The device is intended for the "qualitative detection of human Chorionic Gonadotropin (hCG) in urine to aid in the determination of pregnancy." This falls under the definition of a diagnostic device as it aims to identify a medical condition (pregnancy) by detecting a specific biomarker (hCG).
No
The device is a physical test strip that utilizes chemical reactions and capillary action to produce a visual result, not a software program.
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 human Chorionic Gonadotropin (hCG) in urine to aid in the determination of pregnancy." This involves testing a biological sample (urine) in vitro (outside the body) to provide information about a physiological state (pregnancy).
- Device Description: The description details the use of antibodies and a ligand-binding system to analyze the urine sample for the presence of hCG. This is a typical method used in IVD tests.
- Mechanism of Action: The test relies on a chemical reaction between components of the test strip and the urine sample to produce a result (colored lines). This is characteristic of an IVD.
- Performance Studies: The document describes clinical studies comparing the device to a predicate device, which is a standard practice for demonstrating the performance of IVD devices.
The fact that it's intended for "non-professional, over-the-counter use" doesn't change its classification as an IVD. Many IVDs are designed for home use.

Device Description
The test utilizes a combination of mouse monoclonal and goat polyclonal antibody in conjunction with a proprietary strepavidin-biotin ligand-binding system to qualitatively detect elevated levels of hCG in urine sample. The assay is conducted by dipping the test strip into the urine sample that has been collected in a cup or clean, dry container and observing for the formation of colored lines. The specimen migrates via capillary action along the components of the test strip to react with the colored conjugate. During migration, hCG molecules in the positive urine sample react with the hCG-specific antibodies, which were conjugated with colored particles, and form a colored line on the "Test Region" of the membrane.
A colored line forms in the test (T) region indicates a positive result; while absence of this colored line indicates a negative result. To serve as a procedural control, a colored line at the control (C) region will always appear, indicating adequate sample volume and proper wicking, regardless of the presence of hCG. Absence of this control line in the C region indicates that the test result is "invalid". Therefore, two colored line show up on the test strip indicating a positive result; one line shows up near the wicking end indicating a negative and one line shows up away from the wicking end indicating an invalid result.
The ACON Quik-Check II Home Pregnancy Test Strip qualitatively detects hCG in urine with a designated cutoff hCG concentration of 25 mIU/mL. This test has been standardized to the World Health Organization Third International Standard. The addition of hLH (300 mIU/mL), hFSH (1,000 mIU/mL), and hTSH (1,000 IU/mL) to negative (0 mIU/mL hCG) and positive (25 mIU/mL hCG) urine showed no cross-reactivity.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Clinical studies were conducted to compare the results of ACON Quik-Check II Home Pregnancy Test Strip to the current ACON Home Pregnancy Test (K993483). The consumer field study included 113 female participants and demonstrated an accuracy of over 99% correlation between the two Strip hCG tests. The retrospective focus group study on reproducibility and precision included 35 female participants and demonstrated an accuracy of over 99% correlation between the two Strip hCG tests. The results also showed that the vast majority of the participants found ACON Quik-Check II Home Pregnancy Test Strip very easy to use, and that they had no trouble understanding the labeling, reading the instructions, or interpreting the results.
Additional laboratory study results on performance include specificity, interference substances. urinary pH, urinary specific gravity, and does hook effect. These results indicate that the ACON Quik-Check II Home Pregnancy Test Strip is robust and will give accurate results under many adverse conditions.
