General Sample Submission FAQs

How do I get my results?
MBL delivers results via E mail in the form of a PDF Certificate of Analysis to the recipients designated in the Laboratory Deliverables section of the New Customer Package.
MBL will only report to a third-party at the consent of Customer.
Upon request, results may also be delivered via fax or USPS mail, if this is your preferred method of delivery.
For multiple recipients of results, we recommend establishing an internal distribution list whereby you can define and maintain such recipients (i.e. labresults@yourcompany.com).
How long do you keep my sample & can I have them back?
Sample Retention Times (after reporting results) are as listed in the table below.
Any repeat, additional, and/or confirmation analysis must be requested by the Customer within the retention time frame.
Repeat analysis performed at the Customers' request will be charged to the Customer if the original results are confirmed.
To limit liability, samples submitted to MBL will not be returned to Customer because they have been stored in a facility which is known to have live pathogens.

Sample Retention Times (After Reporting Results) are as Follows:


Sample Type Retention Time
Qualitative Microbiology Negative Enrichments / Samples – Not Retained
Positive Enrichments / Samples – 24 Hours
Quantitative Microbiology 2 Business Days

How long does it take to get results?

Specific turnaround times for each test can be found in our Test Library.

Our turnaround times are approximate, and do not include weekends or holidays for chemical and some microbiology analyses.

We will always try to begin analysis on the day we receive your samples.  However, samples submitted after 3pm may be held until the next day.

A 50% surcharge will be assessed for samples submitted after 3 pm requiring same day set up for microbiological analysis.

E. coli O157:H7 results are typically reported by 6:00am Tuesday through Friday, 7:00am on Saturday, 2:00pm on Sunday, and 10:00am on holidays.

Alternative terms regarding turnaround times may be arranged on a case-by-case basis.

What is the Sample Description?

This is assigned by You, the Customer, to identify the name of samples submitted to MBL, as indicated on the Sample Submission Form.

You should describe your sample in a way which makes sense to you and is meaningful now and later when referring to your records.

Describing samples in a like and similar manner each time you submit the same type of sample can help you later in comparing data from one lot to another.
