## Indications for Use

WHOLEPOWER Pregnancy Rapid Test Cassette is intended for the qualitative detection of human chorionic gonadotropin (hCG) in urine, as an aid in early detection of pregnancy. WHOLEPOWER Pregnancy Rapid Test Midstream is intended for the qualitative detection of human chorionic gonadotropin (hCG) in urine, as an aid in early detection of pregnancy. WHOLEPOWER Pregnancy Rapid Test Strip is intended for the qualitative detection of human chorionic gonadotropin (hCG) in urine, as an aid in early detection of pregnancy.

## Device Story

WHOLEPOWER Pregnancy Rapid Test (Strip, Cassette, Midstream) detects human chorionic gonadotropin (hCG) in urine. Device uses colloidal gold immunochromatography; hCG in urine binds to colloidal gold-labeled rat anti-beta-hCG monoclonal antibody. Complex migrates via capillary action to nitrocellulose membrane; captured by immobilized anti-alpha-hCG antibody, forming visible red line in test zone (T) for positive result. Control zone (C) contains immobilized goat anti-mouse IgG to verify sample flow. Used by lay persons (OTC) or healthcare professionals in clinics. Provides qualitative visual result in 3 minutes. Aids in early pregnancy detection. No electronic components or software.

## Clinical Evidence

Clinical performance evaluated via method comparison study with 120 women at OB/GYN offices, comparing subject device to predicate. Results showed >98% agreement. Lay person study (n=300) demonstrated 100% positive and >97% negative conformity between self-testing and professional testing. Analytical performance confirmed 25 mIU/mL sensitivity, no hook effect up to 2,000,000 mIU/mL, and no interference from common exogenous substances, pH (4-9), or specific gravity (1.002-1.032).

## Technological Characteristics

Immunochromatographic assay using colloidal gold labeling. Nitrocellulose membrane with immobilized anti-hCG antibodies. Formats: strip, cassette, midstream. Sensitivity: 25 mIU/mL. No energy source, software, or connectivity. Shelf-life: 24 months at 4-30°C.

## 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.
