Join Times staff writer Richard Winton at 9 a.m. today for an L.A. Now Live chat on the Orange County Crime Lab, where more errors were found in its blood-alcohol testing, potentially affecting dozens of DUI cases.

The new discoveries come just weeks after the lab acknowledged inaccurate blood-alcohol test results in 2,200 driving-under-the-influence cases. Prosecutors responded by sending letters to drivers charged with DUIs, including 900 who already had been convicted.

Now, Orange County Sheriff Sandra Hutchens and the county Board of Supervisors have requested that the state department of health review the lab’s procedures and case standards.

Readers can submit their questions and comments for the chat at 9 a.m. and we’ll get to as many of them as we can.
