How to Take the Most Accurate Pregnancy Test at Home
Home pregnancy tests display lines in the result window. The first line, known as the control line, indicates that the test is working. The second line, or the test line, appears if there's enough human chorionic gonadotropin (hCG) in your urine. Other tests might use a plus sign or digital versions to indicate pregnancy.
What Causes a Faint Line on a Pregnancy Test?
A faint line on a pregnancy test can be concerning. It may indicate diluted urine or early pregnancy. A line, no matter how faint, often means a positive result. If uncertain, retake the test or consult a healthcare provider. An evaporation line may also cause a faint line if you wait too long to view the results.
Additional Reasons for a Faint Line on a Pregnancy Test
Other reasons for a faint line include a chemical pregnancy, early miscarriage, fertility conditions, or certain medications. Perimenopausal or post-menopausal individuals may also have higher hCG levels. If unclear on the results, continue testing at home or with a healthcare provider.
Yes, Pregnancy Tests Can Expire. Here's What to Know.
False positives and negatives can occur with at-home pregnancy tests. User error, such as not keeping the test in the urine long enough, can alter results. False negatives are likely if the hCG level isn't high enough yet. If you think you're pregnant but have a negative test, try again in a couple of days.
When to Contact a Health Care Provider
If you see a faint line on a pregnancy test and it persists, it may be time to visit a healthcare provider. A blood test can confirm without doubt whether you are pregnant or not, and more testing can help explain unclear results.
