A blood pregnancy test is a medical test used to determine if a woman is pregnant by detecting the presence of the hormone hCG in her blood. Shortly after the fertilized egg implants into the uterine lining, the developing placenta produces the hormone known as hCG. This test is the Quantitative hCG test (also known as a beta hCG test) and measures the specific amount of hCG present in the blood. It can help determine how far along a pregnancy is, monitor the progress of the pregnancy, and detect potential issues like an ectopic pregnancy or a miscarriage.

Blood pregnancy tests are more sensitive than over-the-counter urine pregnancy tests and can detect pregnancy earlier – as soon as 6 to 8 days after ovulation.

This test is not the sensitive estradiol test but the regular one. It is not recommended for men (it is adequate for pre-menapausal women).  The results from this test are usually available 2 business days faster than the sensitive estradiol test.
