Intended Use
EZ Sure OneStep Pregnancy Test is Excel Scientific, Inc.'s name for OTC use of solid phase migratory chromatography immunoassay in vitro diagnostic test kit for the qualitative detection of human Chorionic Gonadotropin (hCG) in urine.
Device Description
EZ Sure OneStep Pregnancy Test is a sandwich solid phase dyeconjugated non-enzyme immunoassay. When the specimen is added to the reaction device, the gold-sol-antibody conjugate binds to the hCG molecules in the specimen forming an antibody-antigen complex. This complex binds to the anti-hCG antibody immobilized in the position zone in the viewing window and produces a purple-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 purple-pink band in the positive reaction mixture continues to flow through the absorbent device, pass the positive reaction zone, producing a purple-pink color band in the control zone, demonstrating that the reagents and the device are functioning correctly.

Device Description

EZP Sure OneStep Pregnancy Test is Excel Scientific, Inc.'s name for OTC use of solid phase migratory chromatography immunoassay in vitro diagnostic test kit for the qualitative detection of human Chorionic Gonadotropin (hCG) in urine. EZP Sure OneStep Pregnancy Test is based on comparative data with BeSure OneStep immuncassay, an assay for human Chorionic Gonadotropin currently being marketed.

The Principle of EZP Sure OneStep Prognancy Test is as follows:

  • Both the EZP Sure OneStep Pregnancy Test and the BeSure OneStep Prograncy Test are a sandwich solid phase dyeconjugated non-enzyme immunoassay. When the specimen is added to the reaction device, the gold-sol-antibody conjugate binds to the hCG molecules in the specimen forming an antibody-antigen complex. This complex binds to the anti-hCG artibody immobilized in the position zone in the viewing window and produces a purple-pink color band when the hCG concertration is at or greater than 25 mlUmL. In the absence of detectable levels of hCG, there is no purple-pink band in the positive reaction mixture continues to flow through the absorbent device, pass the positive reaction zone, producing a purple-pink color band in the control zone, demonstrating that the reagents and the device are functioning correctly.

The Differences Between the EZP Sure OneStep Pregnancy Test and the BeSure OneStep Pregnancy Test are as follows:

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Accuracy:
A study was performed using a total 100 positive urine specimens. These specimens were assayed with EZP Sure OneStep Early Pregnancy Test and Syntron's BeSure test according to the packaging insest.

EZ Sure OneStep Early Pregnancy Test
(Positive)(Negative)
Syntron's BeSure OneStep hCG Test(Positive)900
(Negative)070
The above data do not include two specimens which were weakly reactive with both BeSure OneStap hCG and EZ Sure OneStep Early Pregnancy Tests. The reactions of these specimens were considered to be includive). The accuracy study was also performed by determining the qualitative recovery of known amounts of hCG added to the urine pool.
Concentration of hCG in the Urine Pool (miU/mL)ExpectedObserved

20negativeone band (negative).
25positivetwo bands (positive)
100positivetwo bands (positive)
450,000positivetwo bands (positive)

The EZP Sure OneStep Early Prognancy Test can detect hCG in urine sample at concertration of 25 mill/mL or greater. This senativity has been determined against the World Health Organization Third International Standard. In some cases, samples containing less than 25 mlU/mL of hCG can also test as positive.

Specificity:
Menopousal Urines:
A study was conducted using urine speciment from 20 postmenspeased women. These speciments were chosen because unhe from postmenopausal women frequently interfore with prograncy tests due to cross reactivity with other gonadoropin hormones. All twenty urine specimens were negative when teeted with the EZP Sure OneStep Early Pregnancy Test.

Potentially interfering substances were added to urine samples which had hCG invels of 0 and 25 mlUmi. In each case. no interference was observed when these spiked urine samples were tested with the EZP Sure OneStep Early Prograncy Tost.

Standardization:
The reference preparation and controls have been calibrated as follows:
1.0 mlU/mL Excel = 1.0 mlU/mL 3rd I.S.

Precision:
Intra-Assay: Within run precision was determined using 11 replicates of four specimens containing 0, 25, 100 and 450,000 mlU/mL hCG. The negative and positive values were correctly identified 100% of the time.

Inter-Assay: Between run precision was determined using the same four specimens of 0, 25, 100 and 450,000 mIU/mL of hCG in 11 independent assays, and with three different lots of reaction devices over a two-month period. Again, the negative and positive values were correctly identified 100% of the time.

Summary of Safety and Effectiveness

EZQ Sure OneStep Pregnancy Test

EZ $ Sure OneStep Pregnancy Test is Excel Scientific, Inc.'s name for OTC use of solid phase migratory chromatography immunoassay in vitro diagnostic test kit for the qualitative detection of human Chorionic Gonadotropin (hCG) in urine. EZP Sure OneStep Pregnancy Test is based on comparative data with BeSure OneStep immuncassay, an assay for human Chorionic Gonadotropin currently being marketed.

The Principle of EZQ Sure OneStep Prognancy Test is as follows:

    1. Both the EZ9 Sure OneStep Pregnancy Test and the BeSure OneStep Prograncy Test are a sandwich solid phase dyeconjugated non-enzyme immunoassay. When the specimen is added to the reaction device, the gold-sol-antibody conjugate binds to the hCG molecules in the specimen forming an antibody-antigen complex. This complex binds to the anti-hCG artibody immobilized in the position zone in the viewing window and produces a purple-pink color band when the hCG concertration is at or greater than 25 mlUmL. In the absence of detectable levels of hCG, there is no purple-pink band in the positive reaction mixture continues to flow through the absorbent device, pass the positive reaction zone, producing a purple-pink color band in the control zone, demonstrating that the reagents and the device are functioning correctly.
