Question: What is the likelihood a babies meconium will test positive?

 aaronswifey88 - Mon Jul 26, 2010 11:46 am

A friend of mine tested positive for marijuana at 14 weeks during her pregnancy and they told her that they may test the baby and CPS may get involved when it is born because of this--they told her they were required to flag her to CPS because of this. She said she used once at about 21-23 weeks and that SHE tested negative at her 28 weeks appointment but is worried the babies meconium will still test positive. What is the likelihood that this will happen even though she only used once?

User avatar Hello,
Usually testing is only done if there is suspicion about the mother's competency and/or drug use that might interfere with her ability to parent. Meconium is not usually present unless the baby is past the due date and has a bowel movement before delivery. If she is using drugs at the time of delivery they may check the baby but otherwise, it is unlikely. And, if the mother is negative it is unlikely the baby would show it.

Best wishes.
