Frequently Asked Questions

Is XCellR8 GLP accredited?

Yes we are. Our Good Laboratory Practice (GLP) accreditation by the UK’s MHRA (Medicines and Healthcare Products Regulatory Agency) means that we can provide you with in vitro safety test data that can be used for compliance with a wide range of European and global regulations.

Why do you need to know the purity of my test item?

Noting the purity of the item being tested is part of our GLP (Good Laboratory Practice) compliance. For certain tests, it allows us to ensure the correct concentration is being tested. It’s also another piece of key information that we check to make sure we have the right test item, and you get the right result.

Can you perform an Ames test at your laboratory?

We don’t provide the Ames test, as it uses animal components. We do provide the BlueScreen assay, a genotoxicity test that covers all types of genotoxicity: anugens, clastogens, and mutagens.

We don’t use a Purchase Order system or else Purchase Orders take a long time to issue in my organisation. Can I still start my study?

Yes. In these circumstances, we will usually issue the invoice at the beginning of the study and ask for payment within 30 days.

Where should I send my sample?

Please send all samples to XCellR8 (labs) Techspace One, Keckwick Lane, Daresbury, Cheshire, WA4 4AB, UK

When will I receive my final report?

Most of our tests take 6-8 weeks from receipt of your sample to the first draft report, although please note sometimes it can be slightly shorter or longer depending on the test. We ask for your comments on the draft report within a week, and your final report will be with you after we’ve then completed our final QA checks.
