Within 9 days after fertilization , the egg moves down the fallopian tube into the uterus and attaches (implants) to the wall of the uterus.
When the fertilized egg implants, the placenta starts to develop and begins to release h CG into the woman's blood. In the first few weeks of pregnancy, the amount of h CG in the urine gets higher very quickly-it doubles every 2 to 3 days. The first urine of the morning (that has collected in the bladder overnight) is the best one to use and has the most accurate test results.
Some pregnancy tests are more sensitive than others.
The more sensitive tests may be able to detect low levels of h CG as early as four days before your period is due, which is usually about seven days after you’ve conceived.
The test consisted of purified water, a test tube containing sheep red blood cells and a medicine dropper.
It also relied on getting a urine sample to test for h CG, and it took two hours to obtain the results.
