Am I pregnant? Most of us have been perplexed about this at some point of our lives. But, with the advent of early pregnancy tests, it has now become easy to address this issue early on. And in certain cases even before you have crossed the date of your missed period. So, how do you go about detecting the status of your pregnancy; as you approach the fag end of your menstrual cycle? How do Home Pregnancy Tests Work? Most home pregnancy tests are designed to detect the presence of human chorionic gonadotropin (hCG) in your urine. This pregnancy hormone is released after the embryo embeds itself in the endometrium. A pregnancy dipstick is immersed in a small sample of your concentrated urine and then analyzed for results. You can also dip the stick in your free flowing urine or in a sample collected in a cup. But you must remember to take this test in the morning-when your urine is most concentrated. Accuracy of a Pregnancy Test: The accuracy level claims for some first first response pregnancy test can prove to be misleading. While most of these early pregnancy test kits imply to maintain an accuracy rate of 99 percent or better, there are instances when a much lower rate of 45-80 percent can be expected. The rate of reliability of these tests is dependent on the levels of HCG -a pregnancy hormone in the urine. Most dipsticks present in the test kits are capable of detecting hCG only after you have crossed your date of missed period. Sensitivity of Early Pregnancy Tests
Accuracy of pregnancy tests is directly proportional to the sensitivity of the dipstick in detecting the levels of hCG. Most sensitive tests can detect up to 25 mIU of hCG within a day of a missed period. This is true for 90 percent of women. Less sensitive tests are recommended for women who may have traces of hCG in their system -left behind by fertility drugs, miscarriages or a recent childbirth. The package insert gives fair idea about the sensitivity of the test. They provide a peep into the lowest levels of mIU concentration of hCG, capable of being detected by the test. So, a test which can detect hCG at 25 mIU is considered to be more sensitive and effective than the one which claims to detect this hormone at 40 mIU. What’s the best Time to go Through a Home Pregnancy Test?

It is better to go through the test when you are a bit further down in your pregnancy. ovulation test kits Australia are reliable and affordable and come with high degrees of sensitivity-to give you positive and true results.
