Qiagen QuantiFeron-TB Gold Plus

Qiagen is launching the QuantiFeron-TB Gold Plus test in the US. It is the fourth generation of the blood-based test for tuberculosis infection, and was approved by the US Food and Drug Administration in June. The immunoassay detects the release of interferon-gamma as a proxy for latent tuberculosis infection. The newest generation adds CD8 antigens and workflow improvements that allow for more efficient implementation, especially in large-scale TB screening programs. The test will be available in the US starting Oct. 9 and was already available in 75 other countries in Europe, the Middle East, Africa, Asia, and Latin America, Qiagen said.
