There are two
types of pregnancy tests, one that requires a blood analysis at
a doctor's office and one that searches for the hCG hormone in urine,
which can be done at a doctor's office or at home. A urine test
that can be done at home, a home pregnancy test or "HPT,"
can be purchased at most grocery or drug stores.
The hCG hormone
is created in a woman's body after a fertilized egg is implanted
in the uterus, which happens for most women about six days after
the egg is fertilized by a sperm. After fertilization, hCG begins
building up in a woman's body.
Home pregnancy
tests are the most popular type of pregnancy test. They are readily
available and inexpensive. Most involve a stick that needs to come
into contact with urine. Once the stick has contacted urine and
after an amount of time has passed--usually ten minutes--a symbol,
color, or word(s) (depending on the brand) reveals whether a woman
is pregnant or not. Home pregnancy test manufacturers claim 99%
accuracy.
The very first
day after a missed period isn't the ideal time to use an HPT since
the egg is not always implanted in the uterus right away. Testing
with an HPT one week after a missed period will, in most cases,
result in an accurate reading. However, most HPT brands suggest
a repeat test to confirm the result.
Blood tests
for pregnancy are very accurate and can tell if you're pregnant
a bit earlier than an HPT. If you need to know if you're pregnant
as soon as you miss your period, a blood test is your best bet.
Once you've
determined that you are pregnant, see your doctor right away to
safeguard your and your baby's health.
