Input: urine specimen in test cup. Principle: capillary action moves urine through gold sol-antibody conjugate pad; hCG-antibody-antigen complex forms; binds to immobilized anti-hCG in reaction zone. Output: rose-pink color band indicates hCG concentration ≥ 25 mIU/mL; control band confirms reagent function. Used in home setting by lay users. Visual interpretation of color bands by user; presence of test band indicates pregnancy; absence indicates non-pregnant state. Benefits: rapid, one-step, qualitative pregnancy determination. ## Clinical Evidence No clinical data provided. Substantial equivalence based on comparative analytical performance data against the predicate device, specifically confirming identical 25 mIU/mL cutoff sensitivity. ## Technological Characteristics Solid phase migratory chromatography immunoassay; non-enzyme; gold sol-antibody conjugate; white membrane with immobilized anti-hCG antibody; absorbent device for capillary flow. Qualitative visual readout. ## 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. ## Predicate Devices - Syntron Quikpac EIA ## Reference Devices - QuikStrip (or E.Z.

EZ%Sure™ Urine DipStick Pregnancy Home Test is based on comparative data with Syntron Quikpac EIA, an assay for human Chorionic Gonadotropin currently being marketed. The Principle of EZ%Sure™ Urine DipStick Pregnancy Home Test is as follows: 1. Both the EZ%Sure™ Urine DipStick Pregnancy Home Test and the QuikStrip (or E.Z. Strip) Pregnancy Home test are a sandwich solid phase dye-conjugated non-enzyme immunoassay. When the EZ%Sure™ Urine DipStick Pregnancy Home Test is placed in a urine test cup containing the urine specimen, the urine will migrate by capillary action. The gold sol-antibody conjugate in the gold sol pad of the EZ%Sure™ Urine DipStick Pregnancy Home Test binds to the hCG molecules in the specimen forming an antibody-antigen complex. This complex binds to the anti-hCG antibody immobilized in the positive reaction zone in the white membrane area and produces a rose-pink color band when the hCG concentration is at or greater than 25 mIU/mL. In the absence of detectable levels of hCG, there is no rose-pink band in the positive reaction zone. The reaction mixture continues to flow through the absorbent device, pass the positive reaction zone, producing a rose-pink color band in the control zone of the white membrane area, demonstrating that the reagents and the device are functioning correctly. 2. The Differences Between the EZ%Sure™ Urine DipStick Pregnancy Home Test and the Syntron's QuikStrip (or E.Z. Strip) Pregnancy Home test are as follows: | | QuikStrip (or E.Z.
