Qiagen N.V announced that it is ready to provide QuantiFERON-TB test kits to make up for the lack of availability of tuberculin for skin tests in Germany. This is in response to the recommendation of the German Central Committee against Tuberculosis (DZK) that public health services and clinics should use modern blood tests to screen at-risk children for tuberculosis (TB) infection during a shortage of tuberculin, a protein extract used in TB skin tests.
