INTENDED USE
The OSOM
®
Card Pregnancy Test is a rapid immunoassay for the qualitative detection of human chorionic
gonadotropin (hCG) in urine as an aid in the early determination of pregnancy. This test is for professional
use in physicians’ offices and clinical laboratories.
SUMMARY AND EXPLANATION
Human chorionic gonadotropin (hCG) is a glycoprotein hormone secreted by the developing placenta.
(1)
After fertilization, the concentration of hCG rapidly rises in both the urine and serum of pregnant women.
The detection of hCG in these fluids is an excellent marker for confirming pregnancy. The OSOM Card
Pregnancy Test is a rapid test which can detect the presence of hCG in urine. The test utilizes monoclonal
and polyclonal antibodies to hCG.
PRINCIPLE OF THE TEST
OSOM Card Pregnancy Test is a solid phase, sandwich-format immunochrom-atographic assay for the
qualitative detection of hCG. Urine is added to the sample well of the Test Device using the pipette
provided. The sample migrates through reaction pads where hCG, if present in the sample, binds to
a monoclonal anti-hCG dye conjugate. The sample then migrates across a membrane towards the
results window, where the labeled hCG complex is captured at a test line region containing immobilized
rabbit anti-hCG. Excess conjugate will flow past the test line region and be captured at a control line
region containing an immobilized antibody directed against the anti-hCG dye conjugate (with or
without hCG complexed to it).
The appearance of 2 black bands in the results window — one at “T: Test” and the other at “C: Control” —
indicates the presence of hCG in the sample. If a detectable level of hCG is not present, only the control
band will appear in the result window.
KIT CONTENTS

(Catalog number 134)).
WARNINGS AND PRECAUTIONS
• For in vitro diagnostic use. Federal law restricts this device to sale by or on the order of a physician.
• Do not use beyond the expiration date printed on the kit or foil pouch.
• The lot numbers may be different on the foil pouch and the kit.
• Use appropriate precautions for the collection, handling, and storage of specimens.
• Dispose of all used Test Devices, pipettes and specimens in suitable biohazardous waste containers.
• Test Devices are stable in the unopened foil pouches until the expiration date. Do not remove the
Test Device from the pouch until needed.
STORAGE
Store OSOM Card Pregnancy Tests at room temperature, 15° – 30°C (59° – 86 °F), out of direct sunlight.
Test Devices are stable until the expiration date printed on the kit or foil pouch. DO NOT FREEZE.
If the control band does not appear when running the test, the Test Cassette or kit may have been
stored or handled improperly or the foil pouch may not have been intact.
SPECIMEN COLLECTION AND PREPARATION
No filtration or centrifugation of urine specimen is required for testing with the OSOM Card Pregnancy Test.
Urine specimens may be collected in any clean, dry, plastic or glass container. For early determination
of pregnancy, the first morning specimen of urine is recommended since it usually contains the highest
concentration of hCG. Urine specimens may be stored at room temperature 15° – 30°C (59° – 86°F) for
up to 8 hours, or refrigerated at 2° – 8°C (35° – 46°F) for up to 72 hours.
