Preanalytical errors can affect cerebrospinal fluid (CSF) protein analysis. Formaldehyde contamination during sample handling caused aberrant electrophoresis and protein level discordance in a recent case study.

Area of Science:

  • Clinical Chemistry
  • Proteomics
  • Laboratory Medicine

Background:

  • Preanalytical variables significantly impact laboratory test results.
  • Accurate cerebrospinal fluid (CSF) protein analysis is crucial for diagnosing neurological disorders.

Observation:

  • A case study revealed discordant CSF protein levels and aberrant electrophoresis.
  • Initial investigation pointed towards a preanalytical interference affecting the sample.

Findings:

  • The preanalytical step involving potential formaldehyde treatment was identified as the source of interference.
  • Laboratory tests confirmed formaldehyde's detrimental effect on CSF protein electrophoresis and quantification.

Implications:

  • Highlights the critical importance of meticulous preanalytical sample handling in CSF protein diagnostics.
