- Additional information
Coliform testing is used as an indicator of general sanitation. They are generally found in soil and water and are prevalent in raw agricultural commodities like flour. A high coliform count can be indicative of sanitation issues. E. coli is one of many species of coliforms and is an indicator of possible fecal contamination. E. coli counts will never be higher than coliform counts. Fecal contamination can never be inferred from coliform results alone. If a product has high coliform counts with no E. coli testing and information concerning possible fecal contamination is desired, the sample will need to be retested for E. coli.

We make every effort to keep our methods and detection limits up to date according to the latest standards and qualifications. If you have any questions regarding the limit of detection/quantification or method references, please contact our Customer Service team at 1-800-245-5615.
Our standard turnaround time is 10 business days for most assays. There are some assays that require a longer turnaround time. We also offer a RUSH service that is half the time of the standard turnaround time of the assay at double the cost of the assay. A few assays that we provide cannot be rushed due to the nature of the test. Please check the specific assay you are interested in regarding the ability to RUSH the turnaround time.
