  "id": "MLC-T-CHM-012070",
  "term": "Time-independent test",
  "field": "Chemistry",
  "definition": "An acute toxicity test that has no fixed end time and instead continues until deaths, or a defined sublethal effect, stop or nearly stop. A plot of median survival time against concentration then levels off at a threshold, or incipient, concentration. Such tests are also called incipient lethality tests, and the plateau is typically reached within about a week to ten days for most chemicals.",
