Important Business Update


Notice of Change: Legal Entity Name Change and Merger

29 July 2021

Dear Valued Customer,

As you know, several years ago, LGC acquired SeraCare Life Sciences, Inc. and Maine Standards Company, LLC to broaden our clinical diagnostics product and service offerings that support accurate and reliable diagnostic results. Effective October 1, 2021, the two companies will become one legal entity known as LGC Clinical Diagnostics, Inc.

As a result, all transactions for Maine Standards Company, LLC and SeraCare Life Sciences, Inc. products, that are scheduled to ship on or after Friday, October 1, will be processed under our new entity name, LGC Clinical Diagnostics, Inc. 

Although we will now be known as LGC Clinical Diagnostics, Inc., it is important to note that the dedicated staff at our facilities in Cumberland Foreside, Maine; Milford, MA; and Gaithersburg, MD will remain the team you and your colleagues interact with on a day-to-day basis. In addition:

  • There is no change to your account manager, customer service contacts, technical support representatives, phone numbers, or email addresses.
  • There is no change to the manufacturing location, processes or teams that build and ensure the quality of our products.
  • There is no change to the location where inventory is stored or the team that picks, packs, and ships our product.

What is changing and what action must you take?  Please review the details below and see the updated forms at the bottom of this page.

For the reasons above, we have been working to improve our operations by consolidating order processing, delivery, and invoicing. To keep accounts payable operations as seamless as possible, we would like to request that you update your records to reflect our new company name as ‘LGC Clinical Diagnostics, Inc.’

Documented below are some additional details to assist with this transition.
