Amnio-dye test

What is amnioinfusion?

Amnioinfusion is the instillation of fluid into the amniotic cavity. Blue dye was injected into the amniotic cavity to see if your bag of water (membranes) are ruptured and if amniotic fluid is leaking out through the vagina.

After the procedure

  • Insert a tampon into the vagina.
  • Leave the tampon in for at least 6 hours.
  • The blue dye may turn your urine a bluish green color. That is normal.
  • Do not take the tampon out when you urinate (pee).
  • After at least 6 hours, you may start changing your tampon. 
    • You can change it about every 6 hours if needed or stop using them.
  • You may have some mild cramping for 2 to 24 hours after.

We are looking for blue dye on the tampon.

  • If there is no blue dye on the tampon, you do not need to call.
    • Keep your scheduled appointment.
  • If there is blue dye on the tampon, call us at 1-319-356-8892 as soon as you can.
    • You can call the next working day between the hours of 8 a.m. and 4:30 p.m.
    • There is no need to call during off hours unless you have other symptoms that worry you.

Call your local doctor at night or on the weekend if you have:

  • Severe cramping
  • Bleeding from the vagina
  • A temperature over 100.4 degrees
  • Any other immediate problems
