What your results can mean
Reading your report
A positive IgM usually suggests a recent or current infection and a positive IgG a past infection or immunity, but your doctor will read the result alongside your symptoms.
If the result is outside the usual range
A positive IgM can point to scrub typhus, an infection from mite bites that responds well to antibiotics. A negative result early in fever does not rule it out.
Who usually has this test
People with fever, headache and body pain, sometimes with a dark scab called an eschar, after time in fields, gardens or forests.
