HI, thanks for using healthcare magicPregnancy
tests detect the level of HCG
hormone in the urine or blood (if a blood level is taken).
The level of this hormone increases as pregnancy progresses.
IT should be detectable in the urine by day 12 to 14 after conception.
To find out definitively whether you are pregnant you may want to consider either a blood HCG or an early detection home pregnancy kit .
These kits can pick up low levels of HCG
I hope this helps
