Arbovirus Antibodies, IgM, Serum
Also known as: ARBO SER M
Use
The Arbovirus Antibodies, IgM, Serum test is designed to detect IgM antibodies specific to various arboviruses in patients who are suspected of being infected. It includes detection of West Nile Virus, California Encephalitis, St. Louis Encephalitis, Eastern Equine Encephalitis, and Western Equine Encephalitis Antibodies. The presence of IgM often indicates a current or recent infection, assisting clinicians in diagnosing arbovirus-related conditions, which often present with similar symptoms.
Special Instructions
Specimen should be collected using a serum separator tube, with plain red also being acceptable. Serum should be separated from cells as soon as possible or within two hours of collection. Parallel testing and convalescent specimens received within 30 days from acute specimens are preferred for accurate diagnosis.
Limitations
False positives can occur, particularly due to the cross-reactivity between other Flaviviridae and Alphavirus family members, such as West Nile and St. Louis viruses or Eastern and Western Equine Encephalitis viruses. Repeat testing or additional testing for other specific arboviruses may be necessary if results are questionable. The test is semi-quantitative, and results should be interpreted in conjunction with clinical findings and history.
