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.
Developers of POC STI platforms and assays said that the tests provide convenience, privacy, and quick results in an area of testing in need of these benefits.
The firm is taking its in-home monitoring systems for COPD and cystic fibrosis, and its professional-use sepsis confirmation system through clinical trials.
The partnership will enable the design, development, and manufacture of a test to rapidly detect dengue, Chikungunya, and Zika viruses.
The assay provides a presumptive diagnosis of dengue virus from patients' serum samples within the first seven days of clinical symptoms.
They have begun field testing near-infrared spectroscopy as an alternative to PCR and ELISA for routine pathogen screening in mosquitoes.
The tests are based on Chembio's Dual Path Platform chromatographic immunoassay technology, which can detect antibodies within 15 minutes using fingerstick samples.
The team paired the SHERLOCK platform developed in Feng Zhang's lab with a protocol that detects viruses directly from bodily fluids in less than two hours.
The latest version of the nucleic acid detection platform uses three CRISPR enzymes, making it more sensitive and capable of smaller quantitative measurements.
