Home Pregnancy Tests
How It Feels
There is no pain or discomfort in doing
a home pregnancy test.
There are no problems with collecting a urine
sample for a home pregnancy test. But there may be a chance that you read the
results wrong. With any home pregnancy test, if the test shows you are pregnant
(positive test), you should see your health professional to confirm the test
and arrange follow-up care. If the test does not show you are pregnant
(negative test), it is still possible that you may actually be pregnant. You
should repeat the test in one week if your menstrual period has not started. If
the repeat test is negative, probably you are not pregnant, but you should talk
to your health professional about why you are not having periods.
If you have missed a menstrual period and have lower abdominal pain, call
your health professional immediately even if the pregnancy test is negative.
You may have an
ectopic (or tubal) pregnancy, which occurs when a
fertilized egg attaches somewhere other than in the uterus. An ectopic
pregnancy could burst a fallopian tube and lead to serious medical

hormone (called human chorionic gonadotropin, or hCG)
in a sample of urine. If you are pregnant, most tests show a color change or a
symbol shows in the indicator area of the test strip or on the part of the test
What Affects the Test
Reasons you may not be able to
have the test or why the results may not be helpful include:
- Taking the test very early in your pregnancy.
HCG may not be found. In this case, the test kit may show that you are not
pregnant when you really are pregnant. This is called a
false-negative result. If you have drunk a lot of
fluid, your urine may be diluted and this may also cause a false-negative
- Having soap in the urine collection cup. This may cause the
test results to show that you are pregnant when you are not pregnant. This is
false-positive result. False-positive results may also
be caused by reading the test at the wrong time, letting the test equipment get
warm, having protein or blood in the urine, or having hCG hormone in the urine
from some other cause.
- Taking certain medicines, such as chlorpromazine
hydrochloride and methadone hydrochloride (Dolophine, Methadose).
- Taking fertility medicines that contain human chorionic
- Not reading the result at the right time as shown on
the instructions. If you read the result too early or too late, the color
change may not be accurate and you will need to retest.
