## Indications for Use

The ACON Quik-Check II Midstream Home Pregnancy Test is a qualitative test for the detection the elevated level of human Chorionic Gonadotropin (hCG) in urine to aid in the determination of pregnancy. It is intended for non-professional, over-the counter use.

## Device Story

Qualitative immunochromatographic assay; detects hCG in urine. Device consists of absorbent fiber tip, result window, control window, and thumb grip. User places tip in urine stream or dips into collected sample; urine migrates via capillary action. hCG binds to anti-hCG-colored particle conjugate; forms colored line in test region if hCG present. Control line indicates valid test. Intended for home use by lay individuals. Provides visual qualitative result to aid in pregnancy determination.

## Clinical Evidence

Consumer field study (n=113). Compared consumer performance against lab professional performance using subject device and predicate. Lab professionals achieved 100% concordance between subject and predicate (77 positive, 36 negative). Consumers achieved 100% negative agreement; 75/77 positive agreement with one discrepant and one invalid result. Demonstrates ability of lay users to perform test and interpret results.

## Technological Characteristics

Qualitative solid-phase sandwich-format immunochromatographic assay. Materials include absorbent fiber tip and membrane. Sensitivity 25 mIU/mL. Standardized to WHO 3rd International Standard. No electronic components or software.

## Regulatory 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. 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.

G. Intended Use:
1. Indication(s) for use:
The ACON Quik-Check II Midstream Home Pregnancy Test is a qualitative test for the detection of the elevated levels of human Chorionic Gonadotropin (hCG) in urine to aid in the determination of pregnancy. It is intended for non-professional, over-the-counter use.
2. Special condition for use statement(s):
Non-professional, over-the-counter use
3. Special instrument Requirements:
N/A

H. Device Description:
The device consists of an absorbent fiber tip with a cap at one end, a result window and control window in the middle, and a thumb grip at the other end. When the tip absorbs urine (either through placing in the urine stream or by dipping into a collected urine sample) the urine migrates via capillary action. hCG if present reacts with an anti-hCG-colored particle conjugate to form a colored line in the test region of the membrane. A colored line in the control region of the device indicates adequate sample volume and capillary action. Absence of a colored line in the control region is an indication of an invalid result.

no variation from expected results. Also tested were variations in pH (5-9), specific gravity (1.003 – 1.028) and the addition of 22 common compounds, none of which showed any variation from the expected results.

f. Assay cut-off:
See detection limit above

2. Comparison studies:
a. Method comparison with predicate device:
A consumer field study was done which included 113 participants. Urine samples were analyzed using the new device by both consumers and lab professionals and with the predicate device by lab professionals. The study evaluated the participants’ ability to understand the package insert and to accurately perform the test. When tested by lab professionals, 77 samples tested positive by both methods and 36 samples tested negative by both methods. When tested by consumers, the same 36 samples tested negative. Of the 77 positive samples, 75 tested positive with one discrepant result and one invalid result.

5. Expected values/Reference range:
Human Chorionic Gonadotropin is not found in healthy males or healthy non-pregnant females in concentrations that can be detected by the ACON Quik-Check II Midstream Home Pregnancy Test.

M. Conclusion:
Based upon the information provided for the file, I recommend that the ACON Quik-Check II Midstream Home Pregnancy Test is substantially equivalent to the predicate device.
