In the spring of 2014, the Ebola virus (EBOV) strain Zaire caused a dramatic outbreak in several regions of West Africa. The RT-PCR and antigen capture diagnostic proved to be effective for detecting EBOV in blood and serum. In this paper, we present data of a rapid antigen capture test for the detection of VP40. The test was performed in a microfluidic chip for immunofiltration analysis. The chip integrates all necessary assay components. The analytical sensitivity of the rapid test was 8 ng/ml for recombinant VP40. In serum and whole blood samples spiked with virus culture material, the detection limit was 2.2 x 102 PFU/ml. The performance data of the rapid test (15 min) are comparable to that of the VP40 laboratory ELISA.
