METHOD FOR PREDICTION OF SEVERITY OF HAEMORRHAGIC FEVER WITH RENAL SYNDROME Russian patent published in 2025 - IPC G01N33/68 G01N33/573 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to clinical laboratory diagnostics, biochemistry, pathological physiology, therapy and infectology, and can be used for the prediction of a severity of haemorrhagic fever and renal syndrome (HFRS). Patient’s blood biochemical index Cystatin C is measured. If its quantitative content is 1.76-1.93 mg/l, a moderate degree of HFRS is predicted, 1.94-2.42 mg/l – severe clinical course of HFRS, 2.43 mg/l and more – severe clinical course of HFRS complicated by acute renal insufficiency.

EFFECT: method provides the possibility of reducing labour intensity and increasing the accuracy of predicting the severity of HFRS and a high risk of acute renal failure in the early stages of the disease, by determining the content of a specific diagnostic marker – Cystatin C, in the blood, serving as an indicator of tubular renal dysfunction, and able to predict the early development of acute renal insufficiency.
