Labcorp Introduces Hepatitis D Reflex Test for Early Detection
Labcorp has launched a hepatitis D reflex test, automatically screening for hepatitis D in patients who test positive for hepatitis B. The test aims to improve early diagnosis and streamline workflows. According to Labcorp, fewer than 20% of hepatitis B patients are currently screened for hepatitis D, despite an estimated 70,000 to 150,000 active cases in the US. The company hopes this will lead to earlier treatment and better patient outcomes.
