Antibodies to Bartonella henselae IgG

The presence of IgG antibodies indicates a past infection or acquired immunity following exposure. This test can also help diagnose chronic or recurrent infections, especially in immunocompromised individuals.

When Should You Take This Test?

• To confirm a past Bartonella henselae infection.
• If experiencing recurring symptoms, such as:
  • Persistent swollen lymph nodes,
  • Chronic fatigue, weakness,
  • Recurring muscle and joint pain.
• For individuals with weakened immune systems, where infections may present atypically.

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.
