Diagnostic studies
- The main purpose is to detect the virus in the blood, which can be accomplished by a few tests.
- RT-PCR (reverse transcriptase-polymerase chain reaction) and ELISA test (for antigen detection) may be used during the initial phase of the illness.
- IgM Antibodies : Once the viral load decreases in the blood, IgM antibody tests are helpful in detecting the presence of ongoing infection.
- IgG Antibodies : In recovered cases, testing for IgG antibodies aid in identifying cases who may have had a recent episode of RVF.
Common Lab Findings
- In majority of cases, lab findings will not be significant for anything else except fever and low blood pressure.
- Low hemoglobin levels, raised bilirubin levels along with deranged blood coagulation profile and decreased platelet counts are seen in hemorrhagic RVF.
- Increased leukocytes in CSF along with presence of viral load in CSF would indicate encephalitis or meningitis due to RVF.
