Early detection pregnancy tests are the pregnancy tests that can detect a pregnancy at the earliest stage before the period has been missed.
They are more sensitive than a standard pregnancy test kit and detect lower levels of the hormone hcg . This hormone is released in large quantities during early pregnancy and rises rapidly. It can be detected in the urine They are also know as ultra pregnancy tests or sensitive pregnancy tests.
Most standard home pregnancy test kits will give a positive result when the level of hcg reaches 25mIU in the urine. An ultra early detection pregnancy test will give a positive result when the hormone level reaches just 10mIU hcg in the urine making it far more sensitive and able to detect a pregnancy at an earlier stage. This can be as early as 8-10 days after ovulation or assisted conception.
