Adhesions typically begin to form within the first few days after surgery, but they may not produce symptoms for months or even years. As scar tissue begins to restrict motion of the small intestines, passing food through the digestive system becomes progressively more difficult. The bowel may become blocked.
At the time of implantation, the placenta starts making the pregnancy hormone hCG, which then enters the blood stream. hCG can be detected in the blood about 3 to 4 days after implantation. Urine hCG can be detected about 2 to 3 days after blood hCG can first be seen. Detection of hCG depends on timing of implantation so hCG can normally be detected in the blood between 9 and 16 days after ovulation (HPT: 12-19 days after ovulation).
The human chorionic gonadotropin (hCG) test is done to check for the hormone hCG in blood or urine. Some hCG tests measure the exact amount and some just check to see if the hormone is present. HCG is made by the placenta during pregnancy.he level of hCG in the blood is often used as part of a screening for birth defects in a maternal serum triple or quadruple screening test. Generally done between 15 and 20 weeks, these tests check the levels of three or four substances in a pregnant woman's blood.
