Intended Use
The Evidence Pregnancy Test is a qualitative, one-step assay for the detection of human chorionic gonadotropin (hCG) in urine. The Evidence Pregnancy Test is intended to be used by the lay consumer.
Device Story
Evidence Pregnancy Test is a lateral flow immunoassay for qualitative detection of hCG in urine. Device utilizes monoclonal-dye conjugate and polyclonal-solid phase antibodies. Urine flows through absorbent material; antibody-dye conjugate binds hCG; complex binds to anti-hCG antibody in positive reaction zone, producing pink-rose band at concentrations >25 mIU/ml. Control zone confirms reagent function via unbound conjugate. Intended for lay consumer self-use. Results provide early pregnancy detection, aiding clinical decision-making regarding pregnancy status.
Clinical Evidence
Clinical trials conducted with professional users and lay consumers (n=100 per study). Professional comparison against Pregnosis showed 100% sensitivity, 60% specificity, 98% accuracy. Comparison against Cards + Q.S. showed 100% sensitivity, 100% specificity, 100% accuracy. Lay consumer study (n=100) comparing participant results to medical technologist results showed 100% sensitivity, 100% specificity, and 100% accuracy, confirming suitability for home use.
Technological Characteristics
Lateral flow immunoassay; monoclonal-dye conjugate and polyclonal-solid phase antibodies; visual readout (pink-rose color bands); sensitivity threshold 25 mIU/ml hCG; manual, single-use test device.
Indications for Use
Indicated for the qualitative detection of human chorionic gonadotropin (hCG) in urine to confirm pregnancy in lay consumers, as early as the first day after a missed menses.
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.

## PRODUCT DESCRIPTION:
Evidence Pregnancy Test is a pregnancy test to be used for detecting human Chorionic Gonadotropin (hCG) in urine. The presence of hCG usually appears about the eighth or ninth day after fertilization. The Evidence Pregnancy Test will detect hCG in urine as early as the first day after a missed menses. The Evidence Pregnancy Test will be made available to the lay consumer.
## INTENDED USE:
The Evidence Pregnancy Test is a qualitative, one-step assay for the detection of human chorionic gonadotropin (hCG) in urine. The Evidence Pregnancy Test is intended to be used by the lay consumer.
## SUMMARY OF TECHNOLOGY:
The Evidence Pregnancy Test employs a unique combination of monoclonal-dye conjugate and polyclonal-solid phase antibodies to selectively identify human Chorionic Gonadotropin (hCG) in urine. As the urine flows through the absorbent portion of the device, the antibody-dye conjugate binds to the hCG forming an antibody-antigen complex. This complex binds to the anti-hCG antibody in the positive reaction zone and produces a pink-rose color band if hCG concentration is greater than $25\mathrm{mIU / ml}$. In the absence of hCG, there is no line in the positive reaction zone. Unbound conjugate binds to the reagents in the control zone, producing a pink-rose color band, demonstrating that the reagents are functioning correctly.

# PERFORMANCE DATA:
A clinical trial was done to confirm the performance of the Evidence Pregnancy Test. These data clearly demonstrate that the performance of the Evidence Pregnancy Test is substantially equivalent to the Hoffman La-Roche Pregnosis Pregnancy Test.

% Positive Predictive Value = 97.94%
* Note: False positive results were tested with Pacific Biotech Cards + Q.S. and were confirmed positive. Both the Evidence Pregnancy Test and the Cards + Q.S. detect levels of hCG in urine at 25 mIU/ml. The Pregnosis Pregnancy Test will detect only 1.5 to 2.5 IU/ml of hCG in urine which is approximately 42 days after conception. The Evidence Pregnancy Test is more sensitive than the Pregnosis Test.
