• What happens when a woman is not pregnant during the test?

  The urine washes the unfixed beads away
• What indicates a positive pregnancy test result?

  The entire strip appears blue
• What do the blue beads on the test strip contain?

  Monoclonal antibodies specific to hCG
• What is the difference between the right and left sides of the test strip?

  The right side has fixed antibodies, left has free beads
• How does the presence of hCG affect the movement of blue beads?

  hCG binds to beads, trapping them on the strip
• What is the purpose of the second line in most pregnancy tests?

  It acts as a control line for accuracy
• What should users do before using a pregnancy test?

  Read the instructions carefully
• What are the main components of a pregnancy test strip?

  • Fixed monoclonal antibodies on the right
  • Free blue beads with monoclonal antibodies on the left
• What is the process of how a pregnancy test works?

  1. Urine is applied to the test strip.
  2. If hCG is present, it binds to blue beads.
  3. Beads flow to fixed antibodies and get trapped.
  4. The strip turns blue, indicating a positive result.
• What variations exist among different pregnancy tests?

  • Different tests may have different designs
  • Some tests may show results in various formats
