Pregnancy Test, Serum (Positive or Negative)

The Pregnancy Test, Serum is a blood test that detects the presence of human chorionic gonadotropin (hCG) to determine whether pregnancy is positive or negative. hCG is a hormone produced shortly after implantation and can be detected in the blood earlier than many urine pregnancy tests. This test is commonly used to confirm early pregnancy or to rule out pregnancy prior to medical procedures or treatments. It does not measure the amount of hCG; results are reported only as positive or negative.
