In rare cases, a woman can have abnormally high levels of HCG even though they are not pregnant.

Non-Invasive Prenatal Testing (NIPT) screening: This cell-free fetal DNA test can be done as early as after 10 weeks of pregnancy.

The test can detect levels of hCG in your body through your urine. It's most accurate testing with your first morning urine, according to the Food and Drug Administration (FDA). With a blood test for pregnancy, your hCG levels are measured to help determine exactly how old your fetus is.
