Researchers at the National Institutes of Health (NIH) have found a new blood test for evaluating disease severity in pulmonary arterial hypertension (PAH) patients.
The test quantifies the DNA fragments, known as cell-free DNA, released by damaged cells.
These fragments were found to be high in the blood of PAH patients and increased with the severity of the disease.
The blood test for PAH patients is expected to allow healthcare providers to act quickly to prevent or slow disease progression and save lives.
