Under normal circumstances, your body only produce significant amount of hCG if you are fraught. The test airstrip contains antibodies that bind to this hormone, lead in a colouring change or a digital message. However, the sensibility of these tests varies. Some marque are contrive to pick up minute amounts of hCG very early, while others take higher density, which can occasionally lead to prove errors if the timing is not exact.
