- Trypsin-Like Immunoreactivity
- Serum Trypsinogen
IRT measures the levels of trypsinogen, an enzyme produced by the pancreas. High levels indicate the presence of cystic fibrosis, and this test is routinely performed on newborn babies as part of routine screening for the disease. A small drop of blood is taken from your baby's foot, placed on special paper then analyzed in the lab. There can be false positives with this test.
