Home pregnancy test. Packet and contents of a 'Boots own brand' home pregnancy test kit. The test works by detecting the hormone human chorionic gonadotropin (hCG) that is present in the urine of a pregnant woman. A dipper (lower right) with an absorbent end is placed in the urine stream,or dipped in a urine sample. Blue lines in windows on the side of the dipper display the results after three minutes. A reference line in the smaller window confirms that the test has worked. A blue line in the results window confirms the presence or absence of hCG. HCG is produced by the placenta,the organ that attaches an embryo to the wall of the uterus | |
