Learn when pregnancy tests may stop providing accurate results and what to do for reliable testing.

0 views

Pregnancy tests work best up until a few weeks into the pregnancy. After the first trimester, levels of hCG (the hormone detected by these tests) can vary, leading to false negatives. For accurate results later in pregnancy, consult with a healthcare provider who can perform appropriate tests and imaging.
