Intended Use

Platform OneStep pregnancy test is Syntron Bioresearch, Inc. name for OTC use of solid phase immunoassay in vitro diagnostic test kit for the qualitative determination of human Chorionic Gonadotropin (hCG) in urine.

Device Story

Solid phase immunoassay test kit; detects hCG in urine. Principle: sandwich solid phase dye-conjugate non-enzyme immunoassay. Gold-sol-antibody conjugate binds hCG in specimen; complex binds anti-hCG antibody in positive reaction zone. Output: purple-pink color band indicates hCG concentration >25 mIU/ml; control band indicates reagent/device function. Used by consumers in home setting. Results provide qualitative pregnancy status.

Clinical Evidence

Bench testing only; comparative data provided against Besure OneStep immunoassay.

Technological Characteristics

Solid phase immunoassay; gold-sol-antibody conjugate; lateral flow absorbent device; qualitative visual readout; 25 mIU/ml sensitivity threshold.

Indications for Use

Indicated for qualitative determination of human Chorionic Gonadotropin (hCG) in urine for OTC pregnancy detection.

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.

{0} K960117 # Platform OneStep Pregnancy Test ## Summary of Safety and Effectiveness *Platform OneStep* pregnancy test is Syntron Bioresearch, Inc. name for OTC use of solid phase immunoassay in vitro diagnostic test kit for the qualitative determination of human Chorionic Gonadotropin (hCG) in urine. *Platform OneStep* pregnancy test is based on comparative data with *Besure OneStep* immunoassay, an assay for human Chorionic Gonadotropin currently being marketed. The Principle of *Platform and Besure Pregnancy Test* is as follows: The *Platform and Besure* pregnancy test is a sandwich solid phase dye-conjugate non-enzyme immunoassay. As the specimen is added to the reaction device, the gold-sol-antibody conjugate binds to the hCG in the specimen forming an antibody-antigen complex. This complex binds to the anti-hCG antibody in the positive reaction zone and produces a purple-pink color band when hCG concentration is greater than 25 mIU/ml. In the absence of hCG, there is no purple-pink line in the positive reaction zone. The reaction mixture continues to flow through the absorbent device, pass the positive reaction zone, producing a purple-pink color band, demonstrating that the reagents and device are functioning correctly. ### The Differences Between the Two Protocols | Proposed Volume | 6 drops of urine | 4 drops of urine | | --- | --- | --- | | 0.0 ml | 5minutes | 5minutes | | 0.5 ml | No | No | | 1.0 ml | 1 Step | 1 Step | | 2.0 ml | 25 mIU/ml | 25 mIU/ml | | 3.0 ml | Yes | Yes | 16
