Biotin has the potential to impact hCG levels in laboratory analyses. Specifically, women who are taking biotin supplements might experience inaccurately low levels of hCG in blood tests. This can lead to incorrect outcomes on both at-home urine pregnancy tests and clinical assessments. Although elevated hCG levels serve as an early sign of pregnancy, they also play a role in detecting conditions like miscarriage and ectopic pregnancy. Always make sure to discuss any supplements or medications you’re taking with your healthcare provider, especially during pregnancy, to ensure the most reliable and valid outcomes.
