Intended Use

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

Device Story

AimStick™ PBD Combo Pregnancy is a lateral flow immunoassay for qualitative hCG detection in urine or serum. Device utilizes monoclonal and polyclonal antibodies to detect hCG concentrations ≥20 mIU/ml. Operation involves dipping test strip into specimen; capillary action moves specimen along membrane. hCG binds to colored conjugate, forming visible band on specimen zone; control zone band confirms procedural validity. Used in professional clinical settings. Results interpreted visually by healthcare providers to aid pregnancy diagnosis. Standardized to WHO Third International Standard; no cross-reactivity with hLH, hFSH, or hTSH.

Clinical Evidence

Multi-center clinical evaluation compared AimStick™ PBD Combo Pregnancy against a commercially available predicate. Study included 155 urine and 57 serum specimens. Results showed 100% concordance (79/79 positive urine, 76/76 negative urine, 19/19 positive serum, 38/38 negative serum). Analytical sensitivity is 20 mIU/ml hCG. No cross-reactivity observed with hLH (300 mIU/ml), hFSH (1000 mIU/ml), or hTSH (1000 µIU/ml).

Technological Characteristics

Lateral flow immunoassay test strip. Employs monoclonal and polyclonal antibodies for hCG detection. Sensitivity threshold 20 mIU/ml. Standardized to WHO Third International Standard. Non-automated, visual interpretation.

Indications for Use

Indicated for professional use to qualitatively identify hCG in urine or serum to aid in pregnancy determination.

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"

AimStick™ PBD Combo Pregnancy is intended for the qualitative identification of hCG (human Chorionic Gonadotropin) in urine or serum to aid in the 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 dipping the test strip into the specimen and observing for the formation of colored bands. 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 band on the Specimen portion of the membrane. Absence of this colored band suggests a negative result. To serve as a procedural control, a colored band at the Control Zone will always appear regardless of the presence or absence of hCG.

A multi-center clinical evaluation was conducted comparing the results obtained using AimStick™ PBD Combo Pregnancy and another commercially available serum / urine test. The study included 155 urine and 57 serum specimens tested with both assays. The following results were found:

| | Positive Urine Results | Negative Urine Results | Positive Serum Results | Negative Serum Results |
| --- | --- | --- | --- | --- |
| AimStick™ Combo | 79 | 76 | 19 | 38 |
| Commercially Available Combo kit | 79 | 76 | 19 | 38 |

AimStick™ PBD Combo Pregnancy showed a 100% concordance with the other commercially available serum / urine test.

AimStick™ PBD Combo Pregnancy detects hCG concentrations of 20 mIU/ml and greater. The test has been standardized to the World Health Organization Third International Standard. The addition of hLH (300 mIU/ml), hFSH (1000 mIU/ml), and hTSH (1000 µIU/ml) to negative (0 mIU/ml hCG) and positive (20 mIU/ml hCG) urine showed no cross-reactivity.

Dear Mr. O'Connor:

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 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 (QS) 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.
