Fungal Pathogen Detection
Fungal Pathogen Detection
Invasive Fungal Infection Panel
Invasive fungal infections (IFIs) cause 1.5 million deaths annually worldwide. There are 75,000 IFIs annually in the US, with an associated mortality between 20 – 50%[2,3,4]. IFIs can be effectively treated, the high mortality is due to delay in diagnosis, with current tests taking >2 days. Additionally, 50% of IFIs cannot be identified with current tests.
Properties of an ideal next-generation fungal diagnostics.
1) Short time to results
2) Non-tissue biopsy
3) No specialized training
4) Clear and definitive results for all possible fungal infections
Why Zepto can solve the problem
Zepto can solve the problem because GMR can detect single nucleotide polymorphisms (SNPs) and multiplex unlike current fluorescence methods.
Properties of Zepto’s Fungal Panel
1) Only 90 minutes to results because it replaces blood culture
2) Detects pathogens directly from plasma, removing the need for tissue biopsy
3) Fully automated, no specialized training
4) Clearly identifies fungal infections based on genus
Mortality reduces to 11% if diagnosed under 12 hours, saving thousands of lives annually[7,8].
Up to 50% reduction in hospital costs, for a potential savings of 2.25 billion annually[2,9].
Up to 30% reduction in length of hospital stays.
Reduction in antifungals, of which 80% are currently misused[10, 11].
