Multiple Indicators or Abbreviations on the Absorbent Strip

Any drug test indicator strip can have various abbreviated letters on it at different levels like C or O, P, etc. Different indicators mean different types of drugs or other parameters. Sometimes the change of coloring of the strip could also indicate much about the sample. Some common indicators on absorbent are as follows.

  • C indicates the control line, and a line in front of C means the test is working correctly. If a line does appear for C indicates a retest is required, the trial went invalid during any test.
  • Multidrug test strips are capable of detecting multiple drugs by a single sample. And thus, there could be various lines occurring at different lengths of the strip.

These indicator lines’ appearance for each abbreviation means the individual test negative for that particular type of rug. And if no indication appears for a mentioned abbreviation, that means positive for the drug.
