Samples and Testing
Always call (402-472-4484) or FAX (402-472-4474) the FARRP laboratory staff before sending samples. Tell them how many you are sending and for which allergen they need to be tested.
Please send at least 100g of each sample to be run. If you only have less than 1 g, pleasecall the FARRP lab to discuss.
Package well; leakage can contaminate other samples and yield unsuitable results.
Please include a filled-out Sample Request Form with your shipment. This assures we have all needed information for handling your samples.

Hours of Operation
The FARRP Laboratory is open Monday-Friday 8 am – 5 pm. No packages are delivered or processed on weekends to the FARRP Laboratory.
The University of Nebraska and the FARRP Laboratory are closed for New Year’s Day, Martin Luther King Day, Memorial Day, Independence Day, Labor Day, Thanksgiving and the day after, and Christmas Day.
Working holidays are: Presidents Day (third Monday in February), Arbor Day (last Friday in April), Columbus Day (second Monday in October), and Veterans Day (November 11). Because University classes and offices are operational and staffed on these days, alternate holiday time is offered during the December campus closedown periods established by the academic calendar (generally Christmas Eve – January 2nd) in which the FARRP Laboratory is closed for business.
Special Considerations
- Fermentation:
- Allergens that are used as a substrate for fermentation of microorganisms cannot be analyzed using the standard ELISA methods. This is because the microorganisms partially break down the allergenic proteins in the fermentation process, and this renders the proteins undetectable in the assays. However, there can still be active allergenic protein residue present that may pose a hazard to allergic individuals. If you wish to analyze a product containing microorganisms, please contact the FARRP laboratory at 402-472-4484 to discuss the feasibility of this for your sample.
- Hydrolyzed proteins:
- Hydrolyzed proteins cannot be detected using the standard ELSIA methods for allergens. If you wish to analyze for a hydrolyzed protein, please contact the FARRP laboratory at 402-472-4484 to discuss the testing feasibility of your sample.
- GLUTEN PPM NOTE:
- Gluten/Gliadin Analysis 5ppm: can detect gluten from wheat, rye and barley quantitatively with a limit of quantitation of 5 ppm.
Gluten/Gliadin Analysis 10ppm: in addition to wheat gluten, the Fast Gliadin kit is 100% cross-reactive to rye and barley. - Sesame Seed:
- Testing for the presence of intact sesame seed requires special considerations. Please call the FARRP laboratory at 402-472-4484 to discuss the testing feasibility of your sample.
