HCG U/S Rapid Test (Cassette) description:

Los Angeles-based Diagnostic Automation/Cortez Diagnostics, Inc. offers a OneStep Serum/Urine Combo RapiCard InstaTest HCG Pregnancy Test Kit. (cassette format). ��This Pregnancy Test Kit is an immunochromatographic assay designed for qualitative determination of hCG (Human Chorionic Gonadotropin) in serum/plasma or urine specimen.�� There is an appearance of hCG in both urine and serum soon after conception, and its subsequent rapid rise in concentration during early gestational growth.�� This Pregnancy Test Kit is used to obtain a visual, qualitative result for the early detection of pregnancy.�� This pregnancy test kit is for in vitro diagnostic use only.

�

The pregnancy test immunochromatographic device contains a unique set of dye conjugate and immobilized monoclonal and polyclonal antibodies used to produce a distinctive visual pattern indicating elevated concentration of hCG (20 mIU/ml) in the pregnancy test sample in approximately five minutes.�� In the pregnancy test kit procedure, the liquid sample is allowed to migrate through the absorbent area.�� If hCG is present, labeled antibody-dye conjugate binds it, forming an antibody-antigen complex.�� As the reaction mixture continues to flow along the pregnancy test membrane, the complex binds to the anti-hCG antibody in the (T) zone of the membrane, and produces a pink-rose color band.�� Unbound conjugate on the pregnancy test binds to the reagents immobilized in the control (C) zone producing a pink-rose color band, demonstrating proper performance of the pregnancy test kit.

�

To begin the pregnancy test, open the sealed pouch by tearing along the notch.�� Remove the pregnancy test kit from the pouch and use it as soon as possible.�� Draw the urine or serum sample using the pipette provided in the pregnancy test kit, and dispense 4 drops on the sample well of the cassette.

�

Wait for the colored bands to appear on the pregnancy test.�� Depending on the concentration of hCG in the pregnancy test specimen, positive results may be observed in as soon as 40 seconds.�� However, to confirm negative results on the pregnancy test, the complete reaction time of 5 minutes is required.�� It is important that the background is clear before the result is read on the pregnancy test.�� Do not read results after more than 30 minutes.�� A negative result occurs on the pregnancy test when only one color band appears on the control region.�� No apparent band on the pregnancy test region means that no pregnancy has been detected.�� A positive result is produced when distinct color bands appear on both the control and test regions of the pregnancy test. ��Presence of both lines on the pregnancy test indicates that the patient is probably pregnant.�� The color intensities of the pregnancy test bands may vary since different stages of pregnancy have different concentrations of hCG hormone.�� An invalid pregnancy test shows no visible band at all or no colored band appears on the (C) control region of the pregnancy test. ��Repeat with a new pregnancy test kit.

�

If the specimen cannot be tested on the day of collection, store the specimen in a refrigerator or freezer at 2-8��C for up to 48 hours prior to performing another pregnancy test. For prolonged storage, specimens may be frozen and stored below -20��C.�� Frozen specimens should be thawed and stirred before conducting another pregnancy test.�� Do not freeze and thaw the specimen repeatedly.
