Intended Use

The test is a rapid immunoassay for the qualitative detection of hCG in urine. This test is to be used for the early detection of pregnancy. The QuickVue One-Step hCG-Urine is a one-step immunoassay intended for the qualitative detection of hCG in urine. The test is intended for use by health care professionals.

Device Story

QuickVue One-Step hCG-Urine is a rapid, qualitative immunoassay for detecting human Chorionic Gonadotropin (hCG) in urine samples. The device consists of a test cassette; urine is applied to a sample well. The assay relies on immunochemical binding; if hCG is present, a pink-to-red test line appears in the result window alongside a blue procedural control line. If hCG is absent, only the blue control line appears. The device is intended for use by healthcare professionals in clinical settings to aid in the early detection of pregnancy. Results are interpreted visually by the clinician to inform pregnancy status.

Clinical Evidence

Multi-center field clinical trial comparing the device to a commercially available qualitative hCG test. Accuracy exceeded 99%. Additional studies confirmed intra- and inter-assay precision, lot-to-lot consistency, and lack of interference from common drugs, chemicals, and biologicals. Physician office studies demonstrated that personnel with diverse educational backgrounds could perform the test accurately and reproducibly.

Technological Characteristics

Lateral flow immunoassay for qualitative hCG detection. Form factor: Test cassette. Principle: Immunochemical binding resulting in visual color change (pink/red test line, blue control line). Standalone device; no electronic components or software.

Indications for Use

Indicated for the qualitative detection of hCG in urine for the early detection of pregnancy in patients. Intended for use by healthcare professionals.

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 AND EFFECTIVENESS XI.

# Product:

QuickVue® One-Step hCG-Urine

## Manufacturer:

Quidel Corporation 10165 McKellar Court San Diego, California 92121 U.S.A.

## Device Classification:

The device, QuickVue One-Step hCG-Urine, is similar to other FDA-cleared devices used for the qualitative detection of human Chorionic Gonadotropin (hCG) in urine. The test is used in the early detection of pregnancy and is intended to measure hCG, a placental hormone, in serum, plasma or urine (21 CFR 862.1155). The FDA has proposed that hCG test systems be classified as Class II.

## Intended Use:

The test is a rapid immunoassay for the qualitative detection of hCG in urine. This test is to be used for the early detection of pregnancy.

#### Physiologic Basis for the Assay:

Human Chorionic Gonadotropin (hCG) is a glycoprotein hormone secreted by the trophoblastic cells of the developing placenta as early as 7 to 8 days after ovulation. This hormone stimulates the production of progesterone and estradiol, which are required to sustain pregnancy. In normal pregnancy, serum levels of hCG continue to rise during the first trimester to levels as high as 100,000 mIU/mL. Serum hCG is rapidly cleared in the urine and the concentration of hCG in serum is approximately equal to the concentration in urine. HCG is an excellent indicator of pregnancy early in the gestational period.

## Principle of the Test:

Urine is added to the Sample Well on the Test Cassette. Shortly after addition of the sample, a blue procedural Control Line will appear in the Result Window. If hCG is present in the sample, a pink-to-red Test Line will also appear. If hCG is not present, only the blue procedural Control Line will appear.

{1}------------------------------------------------

## Safety and Effectiveness:

Numerous studies were undertaken to document the performance characteristics and the Numbrous studios from of the test to other commercially available products for the qualitative detection of hCG in urine. These studies included the following:

- The test was shown to be similar to other commercially distributed in vitro tests in terms of 1. features and intended use.
- 2. The test was shown to have excellent intra- and inter-assay precision.
- 3. Lot-to-lot consistency analyses showed the test to be reproducibly manufacturable.
- Common drugs, chemicals, and biologicals were shown not to interfere with the test's 4. performance.
- 5. Using samples obtained from women presenting for pregnancy testing, a direct comparison of the test to a commercially available qualitative hCG test was conducted in a multi-center field clinical trial. An accuracy exceeding 99% was observed.
- 6. Physicians' Office studies were conducted to demonstrate that physician office personnel with diverse educational backgrounds and work experience could perform the test accurately and reproducibly.

#### Conclusion:

These studies demonstrated the substantial equivalence of the QuickVue One-Step hCG-Urine test to currently marketed devices which have been reviewed and cleared through the 510(k) notification process. They further demonstrated the suitability of the product for use by health care professionals. Such studies are a critical element in establishing the fundamental safety and effectiveness of the product and its appropriateness for commercial distribution.
