When can beta-hCG detect pregnancy?

Beta-hCG tests can detect pregnancy as early as 6-8 days after ovulation or fertilization. These tests measure the level of the hCG hormone in the blood or urine. However, the accuracy of the test may vary depending on the sensitivity of the test used and individual factors. It's important to note that the earlier the test is performed, the higher the likelihood of false-negative results due to low hCG levels in the early stages of pregnancy. For more reliable results, it is advisable to wait until a missed period or consult a healthcare professional who can guide you on the appropriate timing for testing.
