## Indications for Use

HIGHTOP 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. HIGHTOP 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. HIGHTOP 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

HIGHTOP Pregnancy Rapid Test (Strip, Cassette, Midstream) detects human chorionic gonadotropin (hCG) in urine samples. Device utilizes colloidal gold immunochromatography; hCG in urine binds to colloidal gold-labeled rat anti-beta-hCG monoclonal antibody. Complex migrates along nitrocellulose matrix; 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 output (presence/absence of red lines) within 5 minutes. Assists in early pregnancy confirmation. No electronic components or software.

## Clinical Evidence

Bench testing and clinical performance studies conducted. Analytical sensitivity established at 25 mIU/mL. No hook effect observed up to 2,000,000 mIU/mL. Specificity testing showed no interference from common hormones (LH, FSH, TSH) or exogenous substances. Method comparison study (n=120) against predicate showed >96% agreement. Lay-person study (n=300) demonstrated 100% concordance between self-testing and professional testing results.

## Technological Characteristics

Immunochromatographic assay using colloidal gold labeling. Nitrocellulose membrane matrix. Immobilized rat anti-beta-hCG monoclonal antibody (detector), anti-alpha-hCG antibody (capture), and goat anti-mouse IgG (control). Form factors: strip, cassette, midstream. Qualitative visual readout. No energy source, software, or connectivity.

## 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.
