Can it be detected 10 days after conception

Pregnancy should be sperm egg combination, sperm egg combination 10 days later, after the blood test is generally able to know whether pregnant. But because the value is very low, so can only be used as a reference. Generally sperm egg combination after about 10 days can be detected, but affected by implantation there are slightly different cases, so 2 weeks time may be more accurate. The accurate detection method is to check the hormone in the blood, called chorionic gonadotropin HCG, HCG is the hormone secreted by the embryo itself, but also through the method of urine test, urine test is actually HCG level, but because the urine has been diluted, so the test results may be lower than the blood results, so it may be later than the blood HCG test results. So the first urine bubble in the morning may be a little more accurate, but more accurate is to measure the level of chorionic gonadotropin in the blood.
