Hantavirus IgG Antibody Titration (Serum)
This test measures the level of antibodies in your blood that your immune system produces in response to exposure to hantavirus. Antibodies help identify past or potential infection.
["This test helps doctors assess if you’ve been exposed to hantavirus, which can cause severe illness."]

Why This Test Is Done
Your doctor may order this test if you’ve had recent exposure to hantavirus, such as working in areas with infected rodents, or if you’ve experienced symptoms like fever, muscle aches, or respiratory issues after exposure.
What to Expect Before the Test
No special preparation is needed. You’ll provide a blood sample, usually drawn from your arm in a clinic or lab. The sample is sent to a lab for testing.
What the Test Results Mean
A positive result means your body has produced antibodies against hantavirus, suggesting past exposure. The antibody titer (level) can help determine the timing and severity of exposure. Results are qualitative (positive/negative) rather than a specific number.
Possible Symptoms of Hantavirus Infection
Hantavirus infection can cause flu-like symptoms initially, followed by severe complications like kidney failure, respiratory distress, or shock. Early diagnosis is critical, but this test alone doesn’t confirm active infection—it only shows past exposure.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
This test is primarily used for epidemiological surveillance and exposure assessment rather than diagnosing active hantavirus infection. Antibody levels can remain detectable for months or years after exposure, so they’re useful for tracking past risk rather than real-time diagnosis. It may also be part of a broader evaluation if you’ve had symptoms consistent with hantavirus illness.
