Coronavirus (COVID-19) Update

To ensure the health and safety of the AMCA staff — our headquarters colleagues will be working remotely through at least March 27. As always, they will be available through email and phone.

With the physical setup of the AMCA laboratory lending itself to "social distancing," members of the AMCA laboratory team have requested that they be permitted to maintain operations. AMCA senior leadership has decided to honor this request and will continually monitor the situation, ensuring the team's safety is maintained.

Senior staff is reviewing these decisions regularly and we will alert you should anything change.

Thank you for your understanding. Stay healthy!
