It is possible to diagnose pregnancy to a periods delay by means of blood test on HGCh. It can show positive result in several days after implantation of an embryo in a uterus wall.
Diagnostics of pregnancy by means of the test
The test for pregnancy is the simplest and available method of its diagnostics on early terms. Test strips are impregnated with the special indicator which reacts with a horionichesky gonadotrophin therefore they change color. This hormone is produced in the woman's organism only during pregnancy and pretty fast is defined in biological liquids.
It is possible to carry out this express analysis approximately in 2 weeks after conception. As a rule, the ovulation occurs in the middle of a cycle and the periods have to come in 12-16 days after an exit of the ripened ovum from an ovary. Conception is most probable in the period of an ovulation therefore it makes sense to buy the test only after a periods delay. If to make the analysis earlier, the probability of obtaining false positive result is high.
Concentration of a horionichesky gonadotrophin in blood increases several times each 2-3 days. If the test showed negative result, but the woman continues to doubt lack of pregnancy, it can make the analysis repeatedly in 3-4 days.
Definition of pregnancy on blood test on HGCh
