Does the Hook Effect in Pregnancy Tests Indicate Twins?

Learn why the hook effect in pregnancy tests can cause false negatives and why it doesn't necessarily mean twins or multiples.

No, the hook effect does not specifically mean twins. The hook effect occurs in pregnancy tests when very high levels of hCG (human chorionic gonadotropin) overwhelm the test, causing a false-negative result. It can happen with multiples (twins, triplets) but isn't an absolute indicator of twins.
