Lighting up heart disease without antibodies: Researchers design low-cost blood test for resource-poor clinics

AI Summary

Researchers have designed a low-cost blood test intended to help resource-poor clinics detect rheumatic heart disease without specialized equipment or refrigerated labs. Earlier diagnosis could allow treatment with inexpensive penicillin before the disease causes irreversible heart valve damage.

Rheumatic heart disease (RHD) claims hundreds of thousands of lives each year, devastating children and young adults in low- and middle-income countries where access to specialized ultrasound equipment and refrigerated testing labs is virtually nonexistent. Inexpensive penicillin could stop the progressive valve damage if the disease is detected early, yet millions remain undiagnosed until irreversible heart failure sets in.
