Human chorionic gonadotropin
(hCG) is a glycoprotein hormone secreted by the developing placenta shortly
after fertilization and implantation of the egg. The appearance of hCG soon
after conception and its subsequent rise in concentration during early gestational
growth make it an excellent marker for the early detection of pregnancy. First
morning urine usually contains the highest concentration of hCG and is therefore
the best sample when performing the urine test. However, randomly collected
urine specimens may be used (though you should "hold" your urine for
a few hours before collecting a sample.

1. Remove the test stick
from its foil pouch by tearing at the notch and take the cap off the test stick.
2. To perform the test,
turn the test stick so the absorbent tip is pointing in a downward direction
and hold the test stick in your stream of urine so the urine makes contact with
the absorbent area. Hold it for at least ten seconds so that
adequate urine goes into the absorbent part of the tip. Do not allow
urine to splash into the result window. To prevent urine from splashing
the result window, during application, place your thumb over the interpretation
window while holding the test in the urine stream.
3. Re-cap the pregnancy
test and lay the test flat on a horizontal surface with the result window facing
4.Depending on the concentration
of hCG, positive results may be observed in as little as 40 seconds. However,
to confirm negative results, the complete reaction time of 5 minutes is required.
It is important that the background is clear before the result is read. Do not
read results after the specified reaction time.
OF PREGNANCY TEST RESULTS
After you have completed the pregnancy test, whether you are pregnant or not,
a rose pink color band will appear in the control portion (C) of the window.
This indicates that the Midstream test is working properly. As urine initially
passes through the viewing window, the test band may momentarily be visible.
This is not necessarily indicative of a positive result. Interpret results only
after the complete test reaction time of 5 minutes.
Positive: After the urine has been in the pregnancy test stick for five minutes, you can
conclude that you are pregnant if a rose-pink color band appears in the "test"
portion (T) of the window (this second color band will appear in addition to
the first control color band). See the diagram below.
You can conclude you are not pregnant if no rose-pink color band is seen in
the large test window within 5 minutes. Note: Even if a faint rose-pink color
band is visible in the test window at five minutes, the test is positive.
Invalid: No visible band at all. The control band will not appear if an insufficient
volume of specimen is added into the test kit. Proper procedures may not have
been followed in performing the test. Repeat with a new test kit. Please consult
above instructions and follow precisely. *Important Note from Early-Pregnancy-Tests.com
Regarding Invalid Test Results: The most common reason for an invalid test result
with a midstream test is that urine has splashed into the interpretation window.
This prevents liquid from properly “wicking” up the test and through
the band of dye. Please note that invalid results can nearly always be avoided
by placing your thumb over the interpretation window while holding the test
in the urine stream.

Notes On Pregnancy
- The Urine hCG Pregnancy Test is for in vitro diagnostic use only (for external
- As with all diagnostic tests, a final clinical diagnosis should not be based
on the results of a single test, but should only be made by a physician.
- A negative result obtained from a urine specimen collected from a mother in
very early pregnancy may be due to an extremely low concentration of hCG. In
such cases, the test should be repeated on a fresh specimen obtained two days
- If a urine sample is too diluted, it may not contain a representative urinary
hCG concentration. If a negative result is obtained with a low specific gravity
specimen and pregnancy is still suspected, obtain a first morning urine
specimen and retest.
- Test instructions must be followed precisely to insure accurate results. Please
read instructions and follow exact test procedure. Please check with your doctor
to verify diagnostic results – or if you receive unexpected or inconsistent
