Shameen Shazaib: Sample Transport and Storage – Maintaining Specimen Integrity

Shameen Shazaib, Medical Laboratory Technologist, shared a post on LinkedIn:

“30 Days of Laboratory Essentials

Sample Transport and Storage — Maintaining Specimen Integrity

Proper sample transport and storage are critical steps in the pre-analytical phase that directly impact the accuracy of laboratory results.

Even a correctly collected sample can become unreliable if not handled under appropriate conditions.

Why is proper transport and storage important?

Incorrect handling can lead to:

  • Hemolysis
  • Bacterial growth
  • Degradation of analytes
  • Changes in pH and gases

This can result in inaccurate or misleading results.

Key factors affecting sample integrity

  • Temperature (room temp, refrigerated, frozen)
  • Time delay before analysis
  • Light exposure (e.g., bilirubin-sensitive samples)
  • Proper labeling and packaging

Examples in practice

  • Blood gases must be analyzed immediately
  • Serum samples should be separated promptly
  • Some tests require cold chain transport
  • Bilirubin samples should be protected from light

Common errors

  • Delayed transport to the laboratory
  • Exposure to incorrect temperatures
  • Improper tube handling
  • Mislabeling or leakage

Key Points 

  • Always follow transport and storage guidelines
  • Maintain sample integrity from collection to analysis
  • Use appropriate containers and conditions
  • Proper handling ensures accurate patient results

Maintaining proper transport and storage conditions is essential for reliable diagnostics and patient safety.”
