Candidate Barack Obama's plan for health care included government investment in public health buildings, particularly laboratories.

Public health labs are a first line of defense against public health threats. Their workers test specimens in a West Nile outbreak or an anthrax attack. They monitor drinking water for contamination. They screen for genetic and metabolic conditions in newborns. They track the latest flu virus.

About 300 state and local labs across the country do that work, coordinating with the Centers for Disease Control and Prevention and other federal agencies.

But funding has been an ongoing challenge.

Still, the federal government has invested in modernizing the labs, first as a response to the H1N1 flu outbreak in 2009, and then as part of the Affordable Care Act in 2010, according to the nonprofit association that represents them.

During the flu pandemic, CDC gave $5.5 million to better equip labs. Then Obamacare boosted funding in the Epidemiology and Laboratory Capacity program by $20 million in 2010 and $40 million a year for fiscal years after that.

That money goes to "modernize, equip, and staff public health laboratories," according to the CDC and in 2011 was distributed across 50 states, six major cities and two territories.

That amounts to almost doubling the funding for the lab capacity program, and has "specifically improved the public health laboratory community's ability to manage the electronic data transmission of test orders and results," said Peter Kyriacopoulos, senior director of public policy for the Association of Public Health Laboratories.

Given that budget boost for lab modernization, we rate this Promise Kept.
