Every analyte result on this site is one of five outcomes. Not detected and not reported are different statements about a laboratory's process and are never shown as the same thing here.
Detected
A numeric result was returned for this analyte. The result value is shown in place of a qualifier.
107,734 of 995,055 analyte results in the index (10.8%)
Not detected
The analyte was screened for and no amount was found at or above the laboratory’s limit of detection.
561,953 of 995,055 analyte results in the index (56.5%)
Below quantitation limit
The analyte was detected, but at an amount below the limit of quantitation: present, but too small for the laboratory to report a reliable number for.
320,669 of 995,055 analyte results in the index (32.2%)
Not reported
The laboratory did not report a result for this analyte on this certificate, though the analyte is part of the panel.
375 of 995,055 analyte results in the index (0.0%)
Not tested
This analyte was not run for this batch at all, printed on the certificate as "NT" or "N/A".
4,324 of 995,055 analyte results in the index (0.4%)
A blank or a dash would collapse four different facts into one. This site renders every one of the five outcomes with its own label everywhere an analyte result appears: batch pages, panel tables, and the figures on this page. See how to read a COA for a worked example.
