Leptospirosis IgM antibodies are specific proteins produced by the immune system in response to an infection with the bacterium Leptospira, the cause of Weil's disease. These antibodies are markers in the blood that aid in diagnosing the disease.
Testing for Leptospirosis IgM antibodies is useful when you exhibit symptoms indicative of Weil's disease, such as high fever, headache, muscle pain, and jaundice. It is also advisable after exposure to potentially contaminated water or after contact with animals that may carry the bacterium.
The presence of Leptospirosis IgM antibodies in the blood indicates a recent or active infection with the Leptospira bacterium. This assists physicians in making a diagnosis and determining the best treatment.
A high level of Leptospirosis IgM antibodies indicates a recent or active infection with the Leptospira bacterium. This may suggest the need for medical treatment to prevent complications of Weil's disease.
A low level of Leptospirosis IgM antibodies may indicate the absence of infection or an early stage of infection where the body has not yet produced a significant amount of antibodies. It may also mean that the infection occurred some time ago and the antibody levels have decreased.
