How Soon Will a Blood Pregnancy Test Show Positive Results?
Pregnancy tests can be done using either a blood or urine sample. While both tests are effective at detecting a pregnancy, a blood test is more accurate and can detect a pregnancy earlier than a urine test. So, how soon will a blood pregnancy test show positive results?
When Can a Blood Pregnancy Test Detect a Pregnancy?
A blood pregnancy test can detect a pregnancy as early as seven to 10 days following ovulation. This is approximately one to two days after a missed period. A blood pregnancy test will measure the levels of a hormone known as human chorionic gonadotrophin (hCG) that is secreted in the bloodstream of pregnant women.
When Should You Take a Blood Pregnancy Test?
It is generally recommended that you wait to take a blood pregnancy test until after your expected period date. This will give the test enough time to detect any changes in hCG levels that may indicate pregnancy. If you take the test too early, it could show a negative result even if a pregnancy has already begun.
Types of Blood Pregnancy Tests
There are two types of blood pregnancy tests that are commonly used to determine if you are pregnant:
- Quantitative hCG: This blood test measures the exact amount of hCG in the bloodstream. It is the most accurate test for detecting a pregnancy and can detect a pregnancy very shortly after conception.
- Qualitative hCG: This type of test will only determine if hCG is present in the bloodstream, not the exact amount. It is useful for providing confirmation that a pregnancy exists.
A blood pregnancy test can help you determine if you are pregnant soon after conception. While a urine test can detect a pregnancy up to one to two weeks following a missed period, a blood test is more sensitive and can detect a pregnancy in seven to 10 days following ovulation.
There are two types of blood pregnancy tests: a quantitative hCG test which measures the exact amount of hCG in the blood, and a qualitative hCG test which only determines if hCG is present in the blood. Both tests are accurate, but the quantitative hCG test is considered the most accurate for detecting a pregnancy. It is recommended that you wait to take a blood pregnancy test until after your expected period date.
