Neonatal screening for inborn errors of metabolism in Germany faces challenges. Many blood samples are collected too late or shipped with delays, hindering timely diagnosis and requiring repeat testing.

Area of Science:

  • Biochemistry
  • Pediatrics
  • Public Health

Background:

  • German guidelines mandate neonatal screening for inborn errors of metabolism (IEM).
  • Preanalytical specifications include blood collection between 36-72 hours and rapid transport.
  • Timely screening is crucial for diseases causing early metabolic decompensation.

Purpose of the Study:

  • To evaluate adherence to preanalytical specifications for neonatal screening in Germany.
  • To identify discrepancies in blood collection and sample transportation times.
  • To assess the impact on diagnostic timeliness and sample quality.

Main Methods:

  • Analysis of 149,854 neonatal screening sample data sets.
  • Comparison of recorded blood collection times against guideline requirements.

  • Evaluation of sample shipping delays and their effect on reporting times.

    • Main Results:

    • Significant discrepancies observed between requested and actual blood collection times.
    • 11.5% of samples collected after the 72-hour window; 43% for outpatients.
    • 31.2% of samples exceeded the 72-hour reporting limit due to shipping delays.
    • 0.52% of samples had insufficient quality, necessitating repeat analysis.

    Conclusions:

    • Recommend routine blood collection around the 48th hour, within the 36-72 hour window.
    • Emphasize the need to optimize sample shipping for early IEM diagnosis.
    • Highlight the importance of increased attention to blood sample quality.
