Pregnancy Tests 101


In this video, Dr. Sterling breaks down everything you need to know about pregnancy tests—so you can test with confidence and understand what those lines actually mean.

You’ll learn:

  • The difference between blood (serum) and urine pregnancy tests

  • Why blood tests are more sensitive and provide actual hormone levels (quantitative)

  • How urine tests work, when to use them, and why they sometimes give false negatives

  • Why line darkness does not reliably tell you how “strong” a pregnancy is

  • When (and when not) to retest—and how frequent retesting can create more anxiety than clarity

  • What to do if you get a positive test + bleeding (hint: call your provider right away)

  • What a chemical pregnancy is and how to interpret early positive tests followed by bleeding

  • Which brands are most accurate based on real studies (not just marketing claims)

You’ll also hear about the differences between marketing claims (like “99% accurate”) and independent studies—and why tests like First Response and Clearblue Digital tend to be more reliable than others.
