The platform can detect a single virus in more than 1,000 samples at a time or more than 160 viruses, including SARS-CoV-2, in a small number of samples.

The method detects dengue virus from blood serum or plasma using DNA nanostructures and aptamers and can potentially be read with a portable fluoroscope.

Eurobio Scientific will also develop new test kits for the T-COR 8, a real-time PCR thermocycler originally developed for the US Army.

The point-of-care diagnostics firm tallied $9.6 million in revenues in the second quarter, besting analysts' consensus estimate of $8.8 million.

The firm said that its multiplex point-of-care test uses 10 microliters of blood from a fingertip and provides quantitative results in about 15 minutes.

The firm is working with a new center in Dakar, Senegal, that will deploy new tests based on the platform to support early detection of tropical diseases.

The firm said it has multiple point-of-care tests available in Brazil and anticipates soon fulfilling an order for its dengue, chikungunya, and Zika tests.

The approval advances Chembio’s commercial agreement with Bio-Manguinhos to develop and supply rapid diagnostic tests for Zika, dengue, and chikungunya.

The mass spec-based assay can detect viral proteins eight days after the onset of symptoms, compared to four to five days with  PCR tests, its developers said.

The test is designed to identify and differentiate between Zika, dengue, and chikungunya in serum samples, even in the presence of more than one target.
