Scientists have pioneered a new way to monitor sodium levels in the blood—without drawing a single drop. By combining terahertz radiation and optoacoustic detection, they created a non-invasive system ...

Researchers developed an optoacoustic (OA) terahertz spectroscopy system that can be used for long-term, non-invasive monitoring of blood sodium levels. Their approach successfully reduces signal ...

DEAR DR. ROACH: My mother’s blood test has a sodium level of 130 mEq/L. She is not on diuretics, and she does not have heart or kidney problems. She is on thyroid medication and omeprazole. Do I need ...
