A positive result indicates past or chronic exposure to Brucella bacteria, suggesting infection or long-term immune response.

It generally means no detectable antibodies, suggesting no prior exposure or infection with Brucella.

IgG indicates past or chronic infection; IgM testing is often used alongside to detect recent or acute infection.

People with symptoms of brucellosis, occupational exposure to animals, or suspected chronic infection should consider testing.

IgG alone cannot confirm active infection; doctors may combine results with IgM testing and clinical evaluation.

Repeat testing may be advised to monitor antibody levels or confirm diagnosis if patient's symptoms persist.
