This method will also help speed up the development of new therapies for liver damage.
The test found three different molecules in the blood that are involved in liver damage - called miR-122, HMGB1 and FL-K18.
The study, published in the journal Lancet Gastroenterology and Hepatology, evaluated the level of three molecular markers in more than 1,000 patients requiring treatment after overdosing paracetamol.
They found that this test can accurately predict whether the patient will develop liver problems, and who needs to be treated longer before leaving the hospital when the body abuses paracetamol overdose.
