What is the Brucella Serology Test?

Brucella serology is a blood test used to detect antibodies produced by the immune system in response to Brucella bacteria. Brucellosis is a zoonotic infection transmitted to humans through contact with infected animals or consumption of unpasteurised dairy products.

The test identifies evidence of current or past exposure by measuring specific antibodies. Because Brucella infections can be chronic and difficult to detect by culture alone, serology plays a key role in diagnosis.

This test is commonly used when symptoms are persistent, non-specific, or when there is a relevant exposure history.

Why do I need a test for Brucella?

You may need this test if you have symptoms suggestive of brucellosis and a history of potential exposure to livestock or unpasteurised animal products. Brucellosis can cause prolonged illness if untreated and may affect multiple organs.

Early detection allows prompt antibiotic treatment, reducing the risk of chronic infection or complications such as joint, liver or nervous system involvement.

Symptoms and scenarios where testing is recommended:

• Persistent or recurrent fever
• Night sweats
• Fatigue or weakness
• Joint or muscle pain
• Back pain
• Headaches
• Weight loss
• Occupational exposure (farmers, vets, abattoir workers)
• Consumption of unpasteurised dairy products

Benefits of the Brucella Serology Test

·      Supports diagnosis of brucellosis
Identifies immune response to Brucella infection.

·      Useful when cultures are negative or unavailable
Helps detect infection that may be missed by other methods.

·      Assists early treatment decisions
Enables timely antibiotic therapy.

·      Reduces risk of chronic complications
Early diagnosis helps prevent long-term disease.

·      Suitable for occupational exposure assessment
Valuable for at-risk professions.

·      Non-invasive diagnostic tool
Requires only a blood sample.

·      Supports investigation of prolonged fever
Helps explain persistent, unexplained symptoms.

·      Guides further infectious disease evaluation
Indicates need for specialist referral if positive.

Step-by-Step: How Testing Works

Choose your preferred testing method

You can attend one of our UK partner clinics or arrange a home or hotel visit with a mobile phlebotomist.

Option 1 – In-Clinic Blood Draw

4. Results are delivered securely online.

Option 2 – Home or Hotel Phlebotomy (+£60)

1. Book a UK-wide home or hotel visit at a convenient time.
2. A trained phlebotomist collects your blood sample on-site.
3. The sample is packaged and transported to the laboratory.
4. Results are uploaded digitally without the need to travel.

Your Results Explained

Negative Result

No Brucella antibodies detected.
This suggests no current or past exposure, although early infection cannot be completely excluded.

Low / Borderline Levels

Low antibody levels may indicate early infection or past exposure.
Repeat testing or further investigation may be recommended.

High / Positive Levels

Elevated Brucella antibodies suggest active or recent infection.
Results are interpreted alongside symptoms, exposure history and other investigations.
