Why is screening not recommended by UK NSC?

The 2013 review found that a national screening programme for Biotinidase Deficiency in newborns was not recommended because: -

  • We didn't know how common the condition was in the UK and how many babies were likely to be born with the condition in the future.
  • While some people with the condition are badly affected, some remain well into adulthood and others never show obvious signs of being poorly. A better understanding of why the condition affects people in different ways was needed if treatment was to be directed to those who needed it.
  • The test was not suitable for screening large numbers of babies. Research into different tests was at an early stage and more information was needed.
  • Some countries offer screening for biotinidase deficiency but others don't. The lack of people with the condition has led to some countries withdrawing the screening programme.
