Confirming your pregnancy is now just a few
steps away with home pregnancy test. Find out the relevance of home pregnancy
tests right here.
Before we go into the relevance of home
pregnancy test, we need to first know how or based on what is the pregnancy
test executed. The home
pregnancy tests trace the presence of
a certain hormone called the hCG, or the Human Chronic Gonadotropin in the
urine of the woman. If high levels of this hormone are present in a urine
sample, it means that you are pregnant.
It has been found and observed that if
the test is conducted exactly as per the instructions provided in the kit, then
the results are same as that which is conducted in a doctor’s clinic. You can
know your status right in the comfort of your home and at your convenience,
this is the by far the only distinguishable aspect of getting the test done at
home or at the clinic.
How is this hCG Present?
During a successful
conception, the egg gets
fertilised by the sperm in the Fallopian tube. Within a week to ten days of
time, this moves down through the Fallopian tube into the uterus as it implants
on the wall of the uterus. Post implantation, the development of the placenta
takes place and here is when the hCG hormone begins to get released into the
body of the woman. From the blood, some of the hormone passes into the urine.
In the initial stage of pregnancy, that is, in the first 2-3 weeks the levels
of hCG surges up rapidly, almost doubling the reading within a couple of days.
Thus, this makes an easy determination of possible pregnancy.
Types of Home Pregnancy Tests
Let us have a look at the types of home pregnancy
Strip – This is the most popular type that
uses a test strip or a dip-stick. You can either hold the strip in your urine
stream or dip it in a sample of your urine. If the strip or the dip-stick
changes colour, it affirms the presence of the hCG hormone, thereby confirming
Device – Here, you need to collect a sample of
urine in the cup provided. As you place several drops you will notice a change
of colour in the test device or the cup where the urine gets collected, thereby
signalling that you are pregnant.
It is always recommended that the home
pregnancy tests are conducted in the morning with the first sample of urine of
the day for the most accurate results.
Accuracy of Home Pregnancy Test
Home pregnancy tests can have different
results for every each woman. There can be various reasons for it, like:
- The menstrual cycle and dates of ovulation may not be uniform in every month.
- You do not get to know the exact date of implantation of the egg.
- Every home pregnancy test kit has a different way or device to conduct the test that may vary in recording the presence of hCG with any uniform sensitivity. This will result with varied results.
- Most kits show results when you conduct on the time of the first period missed.
- The levels of accuracy is found to be the highest when the test is conducted a week after the first missed period.
Finally, the relevance of the home
pregnancy test lies on how well you adhere to the instruction provided in the
respective test kit. If it says that you need to hold the test strip on the
stream of the first urine of the day for several seconds, you need to do
exactly that. If it says to test the dip-stick or strip, or use a device on the
first urine, then you need to follow the time mentioned. So it is important to
read the instructions carefully to obtain the most accurate results. And not to
forget always get a confirmation test done after a follow up with your doctor
as you decide on your antenatal health care.
