Immunoreactive trypsin (IRT)

Ερώτηση
Hello
does the IRT test remain significant for a 9-month-old baby? He has a growth retardation (weighing only 3.5 kg). His fecal elastase is positive and he suffers from abdominal distension.
Thank you
Απάντηση
Hello,

Immunoreactive Trypsin (IRT) is an enzyme of pancreatic origin whose value is used in the context of CF neonatal screening. It's a screening test, which alone doesn't lead to the diagnosis CF. IRT serum concentration decreases in the first few weeks of life.

In the case of a 9-month-old baby for whom symptoms and results of fecal elastase may speak for the suspicion of CF, a sweat test should be performed, which is the benchmark test to confirm or not CF diagnosis.
