Hepatitis C HCV-RNA quantification 3.94E+0.5 should refer to HCV-RNA quantification 3.94E+05IU/mI, i.e. 3.94×10^5IU/mI, which is on the high side, suggesting hepatitis C virus infection. Clinically, the normal range of HCV-RNA quantification is less than 10^3IU/mI, beyond which an abnormality can be considered, so HCV-RNA quantification of 3.94E+05IU/mI has deviated from the normal, suggesting hepatitis C virus infection. It is worth mentioning that the elevation of this test alone cannot determine the patient’s condition, when this index is elevated, it should be combined with the patient’s clinical manifestations under the guidance of professional doctors, and further examinations such as CT, liver function, etc., in order to make an accurate judgment. To summarize, HCV-RNA test 3.94E+05IU/mI is a high result, which should be consulted in time.
