Intended Use

Acon™ Combo Pregnancy is intended for the rapid qualitative identification of hCG (human Chorionic Gonadotropin) in serum or urine to aid in the early determination of pregnancy. This test is for professional use.

Device Story

Acon™ Combo Pregnancy is an in vitro diagnostic test for the qualitative detection of hCG in serum or urine. The device utilizes a lateral flow membrane assay incorporating monoclonal and polyclonal antibodies. The specimen is applied to the test device and migrates via capillary action; hCG in the specimen binds to a colored antibody conjugate, forming a visible line in the specimen area if hCG levels are ≥25 mIU/ml. A control line appears to verify procedural validity. The test is intended for professional use in clinical settings to aid in early pregnancy determination. Results are interpreted visually by the clinician based on the presence or absence of colored lines.

Clinical Evidence

Multi-center clinical evaluation compared Acon™ Combo Pregnancy against a commercially available serum/urine membrane test. Study included 159 urine and 73 serum specimens. Results demonstrated 100% concordance with the comparator device. Analytical sensitivity is 25 mIU/ml, standardized to WHO Third International Standard. Cross-reactivity testing with hLH (300 mIU/ml), hFSH (1000 mIU/ml), and hTSH (1000 µIU/ml) showed no interference.

Technological Characteristics

Lateral flow immunochromatographic assay; utilizes monoclonal and polyclonal antibodies; detects hCG at ≥25 mIU/ml; standardized to WHO Third International Standard; visual readout via colored lines; non-electronic; manual operation.

Indications for Use

Indicated for professional use for the rapid qualitative identification of hCG in serum or urine to aid in the early determination of pregnancy.

Regulatory Classification

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.

## "Summary of Safety & Effectiveness"

Acon™ Combo Pregnancy is intended for the rapid qualitative identification of hCG (human Chorionic Gonadotropin) in serum or urine to aid in the early determination of pregnancy. The test utilizes a Combination of monoclonal and polyclonal antibodies to selectively detect elevated levels of hCG. The assay is conducted by adding specimen to the test device and observing for the formation of colored lines. The specimen migrates via capillary action along the membrane to react with the colored conjugate. Positive specimens react with the specific antibody-hCG-colored conjugate and form a colored line in the Specimen Area of the membrane. Absence of this colored line suggests a negative result. To serve as a procedural control, a colored line in the Control Area will always appear regardless of the presence or absence of hCG.

A multi-center clinical evaluation was conducted comparing the results obtained using Acon™ Combo Pregnancy and another commercially available serum/urine membrane test. The study included 159 urine and 73 serum specimens tested with both assays. The following results were found:

| | Positive<br>Urine Results | Negative<br>Urine Results | |
|--------------------------------|---------------------------|---------------------------|-------------------------------|
| Acon™ Combo | 71 | 88 | |
| Commercially<br>Available Test | 71 | 88 | |
| | Positive<br>Serum Results | Negative<br>Serum Results | Inconclusive<br>Serum Results |
| Acon™ Combo | 21 | 51 | 1 |
| Commercially<br>Available Test | 21 | 51 | 1 |

Acon™ Combo Pregnancy showed a 100% concordance with the other commercially available test.

Acon™ Combo Pregnancy detects hCG concentrations of 25 mIU/ml and greater. The test has been standardized to the World Health Organization Third International Standard. The addition of hI.H (300 mIU/ml), hFSH (1000 mIU/ml), and hTSH (1000 µIU/ml) to negative and positive serum and urine specimens showed no cross-reactivity.

Dear Dr. Lin:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we 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). 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 (Premarket Approval), 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 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (OS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
