· Neonatal screening for primary immunodeficiency diseases (PIDs) enables early diagnosis and subsequent initiation of therapy.
· Excision of T-cell receptors and kappa-recombination excision circles are cheaper alternative PID screening methods.
· Sanger DNA sequencing remains the reference method for detecting PID; however, next-generation sequencing technology is increasingly used to diagnose it.
· Here we developed a graphical algorithm for diagnosing primary immunodeficiency syndrome based on modern methods of screening for primary immunodeficiencies in newborns.
