What Is the Difference Between a Blood and Urine Pregnancy Test?

Did you miss your period and think you’re pregnant? A missed period is one of many common symptoms that could point to pregnancy. To confirm you are indeed pregnant, your first step is to take a pregnancy test. While at-home pregnancy tests are 99% accurate, user error can always lead to a false result, so it’s smart to confirm your pregnancy with a lab-quality grade pregnancy test with a medical professional. There is a major difference between a blood and urine pregnancy test, and we want to explain the two so you can move forward with confidence.

How Soon Should I Take A Pregnancy Test?

For a pregnancy test to work and for you to receive accurate results, your body needs time to develop detectable levels of hCG, the “pregnancy hormone.” The best time to take a pregnancy test is one week after your missed period. If you are still unsure that you are pregnant, here are some common pregnancy symptoms:

  • A missed period
  • Swollen, tender breasts
  • Nausea with or without vomiting
  • Increased urination
  • Fatigue
  • Moodiness 
  • Bloating 

Urine Pregnancy Test

The most common type of pregnancy test is a urine test. This test is performed at home or in a clinic. These tests are very simple and easy to use, normally involving urinating on a stick or into a container. They are also known as digital pregnancy tests that could say “pregnant” or “not pregnant.” Whether you use this urine test at home or go into a clinic, urine tests are a very simple process, with a short waiting time to see results.

Blood Pregnancy Test

A blood pregnancy test is less common for women to get when confirming pregnancy. There are two types: a quantitative blood test and a qualitative hCG blood test. A urine pregnancy test picks up a concentration of 50 units of hCG, a blood pregnancy test can pick up as little as 5 units of hCG (explains Daniel Roshan, M.D., ob-gyn at Rosh Maternal-Fetal Medicine in New York City). While this pregnancy test may be taken sooner, it can often involve a long wait to see the results and must be done in a doctor’s office only.
