NPO obtains

concurrence of ICS

and activates

NAHLN lab in state.

Is activated lab at or

near capacity for

testing?

No Yes Contact NPO ASAP.

NPO monitors situation reports for

each state with an activated lab;

NAHLN labs are inactivated 21‐30

d after the last quarantine is lifted

from the last premises in the state

NPO follows up with email to NAHLN

lab director, state vet, APHIS DD/AD,

informing them the lab has been de‐

activated.

All invoicing to NPO for testing

reimbursement must occur within 30

d of deactivation.  

Is testing moving to

recovery and disease

freedom stage of

outbreak?

NPO will coordinate with ICS and

NAHLN laboratory to identify

solutions:

‐ re‐direct samples to another

NAHLN lab

‐ increase capacity of current lab

through additional personnel and/

or equipment

‐ consider use of mobile

laboratories if available

Yes

NVSL confirms positive FAD.

Federal/State regulatory officials initiate

outbreak investigations and stand up ICS.

NPO schedules call with NAHLN lab director to

activate lab. Discussion points include: ‐ # personnel trained,

‐ lab capacity for 8h shifts

‐ max lab capacity for 24h period

‐ IDIQ/task order in place

‐ other factors that may impact the lab’s ability to test

NPO identifies other regional

NAHLN labs, notifies lab director of

potential activation, and issues

task orders to labs that may be

activated.

email to NAHLN lab

director, state vet,

APHIS AVIC outlining
