FDA's narrower LDT plan doesn't satisfy critics
The FDA is going its own way. The agency announced Monday that it will start regulating lab-developed tests, requiring some 12,000 labs to submit their diagnostics for reviews in the next four years. But while the plan is noticeably softer on requirements than a draft version, it's almost sure to face legal threats, STAT's Lizzy Lawrence writes.
The agency's action comes after Congress repeatedly failed to pass legislation that would clear the way for FDA review these types of tests. While lawmakers bandied about bills for years, GOP support, in particular, fell apart after labs mounted a campaign against costly reviews.
The FDA's latest version carves out exceptions for many tests already on the market and gives labs years to submit applications. But critics still question whether the FDA are allowed to make a plan at all without the congressional greenlight. Rep. Cathy McMorris Rodgers, chair of the E&C Committee, quickly blasted the regulation as federal "overreach." More from Lizzy.

H5N1: Here's what we know
Avian flu has been around for decades, but not like this. How are cows getting infected? How might people be at risk? Does consuming milk laced with live H5 virus pose a hazard?
My trusty colleagues Helen Branswell and Megan Molteni delve into what we know about the virus' spread across dozens of herds in eight states, and what we don't — and why we don't.
For instance, farmers who largely haven't been willing to test their cows are also hesitant about getting workers tested as well, hindering a clear picture of transmission. And because of limited data, we also don't have a complete understanding of the risk of viral fragments in milk. More from Helen and Megan.
