My baby is almost 2 months old, after 1 week of birth he suffered with jaundice biluribin 13 then we kept him for photography and came down to 10 but his eyes were still yellowish, now after 2month we observed his eye yellow & got him checked and found biluribin 14 level again we go through phototherapy and now its 9 eyes are white. But doctor suggested us to get the " Genetic testing for crigler najjar syndrome (UG T1 A1).

Please let me know the purpose of this test & further results if it comes positive or negative.

Please revert asap i m very worried. Any long life effect.
