Phe ≤ 4 mg/dL
TSH < 25 mU/L
 
Interpretation:
Abnormal result Must follow the child to recollect blood to confirm result again. If found that Phe level is still high, the doctor has diagnosed PKU, Phenylketonuria(Ex. using special milk). Or if found that TSH, FT4 still abnormal, the doctor will treat for CHT, Congenital Hypothyroidism (Ex. using L-thyroxin)).
