Scientists at the University of Missouri have developed a new test that can detect Rocky Mountain spotted fever in just 40 minutes. This is faster than existing tests and could help save lives.
A team of researchers at the University of Missouri has created a new method to quickly diagnose a deadly tick-borne disease called Rocky Mountain spotted fever.
The current diagnostic tools for this disease are often expensive, hard to access, or unable to detect small amounts of the bacteria in a blood sample. This can lead to delayed treatment and poor outcomes, especially in children.
The new test is called a rapid isothermal RPA–CRISPR/Cas12a assay. It works by mixing DNA from a sample with specialized reagents in two quick steps. After 40 minutes, a change in liquid color indicates a positive detection of the bacteria.
This test can be completed at room temperature without the need for complex and costly laboratory equipment. The researchers hope that this test will eventually be used in rural or under-resourced clinics around the world where advanced laboratory equipment is inaccessible.
Why It Matters
This new test could save lives by allowing doctors to quickly diagnose and treat Rocky Mountain spotted fever, especially in areas with limited access to medical resources.
Key Facts
