Is Blood Test Accurate for Pregnancy Detection? How Long Does It Take to Get the Results?

The accuracy of blood tests for pregnancy is very high, basically reaching 100%. However, it is important that the timing is correct, and the earliest time for a blood test to detect pregnancy should be at least 12 days after sexual intercourse. If you are anxious, you can go to the hospital for this test ten days after your menstrual period, and the accuracy of this test is as high as 99%. hCG stands for human chorionic gonadotropin, which is generally used to determine early pregnancy. In the non-pregnant state, the level is less than 2.9, and a level greater than 10 can confirm pregnancy. It doubles every 1.7 to 2 days, and a blood test can be taken a week after sexual intercourse to confirm pregnancy.

1. The cessation of menstruation is the earliest and most important sign of early pregnancy. It is normal for menstrual periods to be delayed by up to 7 days, but if the delay exceeds 10 days, there is a high possibility of pregnancy. This symptom often leads women to notice other symptoms of pregnancy.

2. One of the obvious signs of pregnancy is that your breasts may become sensitive, swollen, and sore without apparent cause. You may feel discomfort in your breasts when trying to find a comfortable sleeping position, during exercise or bathing, or when dressing.

Blood pregnancy tests are primarily diagnosed through blood hCG levels. The principle of blood tests for pregnancy mainly involves quantitative testing of the hCG content in the blood to determine whether or not a woman is pregnant. Generally, a positive blood pregnancy test result indicates pregnancy 10-14 days after sexual intercourse, while a negative result indicates non-pregnancy. Blood pregnancy tests require fasting, and the procedure usually takes about two to three minutes. The time it takes to receive the test results depends on the specific situation of the hospital, but it generally takes about two hours.
