Thyroid Hormone (TH) (Triiodothyronine and Thyroxine) hormone produced in the thyroid; increases metabolic rate, raises oxygen consumption, increases heat production, secretes growth hormone, promotes alertness, and grows skin, hair, bones, nails, and teeth. Calcitonin.
If you take a pregnancy test before implantation occurs, the test will tell you that youâre not pregnant (since the production of the hCG hormone has not started, this hormone will not be in your system, and the test will not detect it).
Technically you're not pregnant until implantation occurs, so if you mean 1 week after implantation, then YES! A pregnancy test will very likely be accurate 1 week after implantation. By the way, if you get a positive result at any point during your cycle, it is most likely accurate. Pregnancy tests have a very low false positive rate (unless you count squinting at a very faint evaporation line).
