  "id": "MLC-T-CHM-001687",
  "term": "Carry-over",
  "field": "Chemistry",
  "definition": "The unintentional transfer of a small amount of analyte or sample from one measurement or reaction to a subsequent one, leading to contamination. This effect can occur in automated analytical systems due to incomplete washing of probes, tubing, or reaction vessels. It can lead to inaccurate results, particularly for low-concentration samples following high-concentration ones.",
