My newborn's IRT levels

Good morning to all and I want to say thank you in advance for your thoughts/information.


Brief backround:
  • My wife and I had a baby boy 2 weeks ago.
  • 9 days after his birth we received a call in regards to his IRT levels being flagged for high number as it sat @ 224
  • Upon further family history findings: My biological sister is a carrier of the DF508 mutated gene.
  • However while my son's IRT levels were high he did test NEGATIVE for the DF508 gene.
  • He already has surpassed his birth weight/good color and texture in bowel movement/no breathing problems at all/no jaundice/overall looks and acts completely healthy.
  • My wife had a rough delivery and our baby was quite stressed (blood pressure dropping after each contraction) to which the doctor had to do a c-section in addition to pitocin being required.
  • Baby had bowel movement while in the womb and again within 24 hrs after delivery.


Sorry for the rambling but I am very nervous as we just had the IRT tests retaken yesterday.

Overall I guess I was looking for a good sign that perhaps this is a false positive or he is a carrier.

Perhaps this logic is flawed: If my biological sister is a DF508 carrier and my own baby has a negative test for the DF508 gene I take that as a good sign. I may be wrong but I am assuming the same gene one of my parents passed onto her would mirror the same possibility in my genes? And if my son is negative perhaps that would put him at carrier only if my wife has another mutated gene.

Does that logic hold any water? I guess my parents could both have mutated genes and I could still have a different mutated gene passed from the other parent? In addition I have a biological brother who as well has not been tested for a carrier he is overall healthy.


Thank you all for your time and information. I have been on this site since we learned of the IRT test and I thank you all for your support.

Hello! Yes, you're right the baby could have 2 different CF genes. On this site we often recommend that you get your son a genetic test that has the full CF sequencing. There are over 2000 CF mutations. Good luck! Hope your son doesn't have CF, but if he does, everything will be OK, too. Congrats on your new arrival!

If he's doing well, just hang in there until he is old enough to do the sweat test. The IRT is not diagnostic. It's just a flag to do further testing. He should be able to do the sweat test before long.

i would make sure when you do the sweat test it is done at a CFf accredited center. Just go to www.cff.org to see the closest CFf accredited center. Even if it is a drive it is worth it to get an accurate test result.
