Pregnancy testing

  • Urine test positive 2–3 weeks after woman becomes pregnant — about 4 weeks after last period. Less reliable before this and at 8–12 weeks after missed period
  • Blood test can be used to check urine test and to work out how much human chorionic gonadotropin hCG (pregnancy hormone) present
    • hCG increases in early pregnancy
    • Negative result — not pregnant or not enough hCG to be detected at time of test
  • Do test in private place — may not want anyone else to know result or that she is having pregnancy test

Pregnancy testing is done

  • When woman requests it
  • After delayed or missed period/s
  • Before starting new contraception, after late contraception — see Quick Start method 
  • To help exclude pregnancy in vaginal bleeding
  • To help exclude ectopic pregnancy in woman with lower abdominal pain
  • Before giving certain medicines or immunisations

Ask

  • About last period — test may not be reliable if less than 4 weeks ago
  • What result she hopes for — may or may not want to be pregnant
