Bartonella henselae IgM antibodies

The presence of IgM antibodies indicates a recent infection, as these antibodies are produced in the early stages of the immune response. This test is particularly important for patients experiencing swollen lymph nodes, fever, and other symptoms that may suggest a Bartonella henselae infection.

When Should You Take This Test?

• If a recent Bartonella henselae infection is suspected, especially after contact with a cat.
• If you experience symptoms such as:
  • Swollen lymph nodes,
  • Fever, fatigue,
  • Headaches, muscle pain,
  • Skin changes at the site of a scratch or bite.
• For immunocompromised individuals, who may experience more severe symptoms.

How to Prepare for the Test?

No special preparation is required. It is recommended to take the test on an empty stomach, but drinking a small amount of water beforehand is allowed.
