Anti-Hantavirus IgG Antibody Quantitation, Serum
This test measures the level of antibodies in your blood that your immune system produces in response to exposure to hantavirus. Antibodies help your body fight infections.
["This test helps doctors assess past exposure to hantavirus and monitor immune response over time."]

Why This Test Is Done
Doctors may order this test if you’ve had symptoms of hantavirus infection (such as fever, muscle aches, or shortness of breath) or if you’ve been exposed to hantavirus through contact with infected rodents or their urine. It can also be used to check for past exposure in people who have traveled to regions where hantavirus is common.
What to Expect Before the Test
No special preparation is needed. You’ll provide a blood sample, usually drawn from your arm. The blood will be sent to a lab for testing.
What the Test Results Mean
Results show the concentration of IgG antibodies. Higher levels suggest your immune system has recognized and responded to hantavirus. However, antibody levels alone don’t confirm active infection—other tests or clinical symptoms are needed for diagnosis.
Possible Causes of Positive Results
A positive IgG test can occur after exposure to hantavirus, even if you didn’t develop symptoms. It may also appear in people who have recovered from hantavirus infection or those exposed to the virus in the past.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
This test is primarily used for surveillance, research, or monitoring in high-risk populations (e.g., travelers to endemic areas, healthcare workers). It doesn’t replace diagnostic tests like PCR for active infection but can help track exposure history or immune status over time. Always consult your healthcare provider for interpretation.
