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

Both blood and urine pregnancy tests are highly accurate, but there are a few key differences you should be aware of. 

They detect hCG (human chorionic gonadotropin), otherwise known as the pregnancy hormone. This hormone is only produced by the placenta during pregnancy and helps support the developing embryo by thickening the uterine lining. 

During the first ten weeks of pregnancy, hCG levels rise rapidly before plateauing. 

One key difference between the two types of pregnancy tests is that blood pregnancy tests must be conducted at a doctor’s office or medical clinic, while urine pregnancy tests can be conducted in the comfort of your own home. 

When Should I Take a Pregnancy Test?

It is best to wait to take a urine-based pregnancy test until you’ve missed your period. This way, you allow enough time for hCG to develop and lessen the likelihood of a false negative. 

Both blood and urine tests can detect hCG, but blood tests are more sensitive. This is why many doctors have you come in for a blood pregnancy test after receiving a result with a urine-based test. Blood tests tend to be more expensive, however, and require a doctor’s order.
