For urine pregnancy tests:
- In most cases, urine pregnancy tests can detect hCG levels as early as 6-8 days after conception, but this can vary depending on the sensitivity of the test.
- However, it is important to note that the hCG levels increase gradually in early pregnancy, so the test may not always be accurate this early.
- For more reliable results, it is recommended to wait until at least 10-14 days after ovulation (which is about 2-3 days after a missed period) before taking a urine pregnancy test.
For blood pregnancy tests:
- Blood pregnancy tests (quantitative hCG tests) can detect hCG levels earlier than urine pregnancy tests.
- Some blood tests can detect hCG levels as early as 8-10 days after ovulation.
- Blood tests can also provide more precise information about the hCG levels, which can be useful in monitoring early pregnancy or in cases of suspected ectopic pregnancy.
