In North Carolina, our policy is already that venous samples *must* be sent to an outside laboratory to be counted as a diagnostic test. See the Medicaid Bulletin section on Diagnostic Testing for more information.
The FDA is warning facilities such as laboratories or health clinics that Magellan Diagnostics’ LeadCare Testing Systems may underestimate BLLs and give inaccurate results when processing venous blood samples. The FDA is providing recommendations to help mitigate the risk of inaccurate test results to assure that patients receive accurate information regarding potential lead exposure. The FDA is also strongly urging parents and at-risk adults to speak with their health care provider about the U.S. Centers for Disease Control’s (CDC) recommendations on re-testing.
