1. A method of identifying erroneous collection of a sample for a measurement of a first species in a collection device comprising a reagent incompatible with a reliable measurement of said first species, said method comprising:

  • taking the sample from said collection device;

    determining a concentration of said first species;

    determining a concentration of a second species in said sample with respect to a threshold value;

    when the concentration of the second species is beyond said threshold value, flagging or suppressing a reporting of the determined concentration of said first species and the determined concentration of said second species, and reporting the collection device as being inappropriate for collection of said sample for the reliable measurement of said first species; and

    when the concentration of the second species is not beyond said threshold value, flagging or suppressing the determined concentration of the first species if the determined concentration of the first species is outside of a reportable range for the first species, flagging or suppressing the determined concentration of the second species if the determined concentration of the second species is outside of a reportable range for the second species, and not reporting the collection device as being inappropriate for collection of said sample for the reliable measurement of said first species,wherein said first species is one of a plurality of species in said sample.
