DIAGNOSTIC TECHNIQUE FOR STAGE OF CHRONIC HEPATITIS C IN RNA-HCV "+" PATIENTS Russian patent published in 2013 - IPC G01N33/48 A61B5/00 

FIELD: medicine.

SUBSTANCE: blood plasma is examined for a prothrombin index, a liver size projecting from an arch of a costal arch is measured, a diseases length as shown by anamnestic data and patient's age at the moment of examination are specified, and a stage of chronic hepatitis C (SCHC) is calculated by a specific formula. The value of 0≤SCHC≤0.50 enables diagnosing a stage of chronic hepatitis C involving no liver tissue fibrosis; the value of 0.51≤SCHC≤1.50 shows a minimal stage, the value of 1.51≤SCHC≤2.50 - a moderate stage, while the value of 2.51≤SCHC≤3.50 provides stating a manifested stage and a cirrotic stage is shown by the value of SCHC≥3.51. The declared technique is the non-invasive diagnostic technique for a stage of CHC in the RNA-HCV "+" patients.

EFFECT: ease to use, lower price, higher accuracy, applicability for regular medical check-ups and enabled well-timed solution of a problem of the beginning of an antiviral therapy.
