Serology (Blood Testing)

Blood tests are undertaken for a number of reasons and can include the following:

  • Assessment for response to vaccination
  • Diagnostically to check whether birds have been exposed to infections or have diseases
  • As part of a routine monitoring programme to check freedom from certain diseases
  • Exports - e.g to check freedom from disease

What tests do we offer?

There are a number of different serological tests that can be undertaken at the laboratory but the most common tests used are:

  • Rapid serum agglutination testing (RSA)
  • Enzyme Linked Immunosorbent Assays (ELISA)

These tests look for evidence of specific agents by the detection of antigens (proteins expressed on the surface of a pathogen) or they look for the birds response to exposure to specific agents by detecting antibodies.

Serological tests that are commonly conducted at Crowshall Veterinary Laboratory include:

  • Mycoplasma gallisepticum (MG) RSA
  • Mycoplasma synoviae (MS) RSA
  • Mycoplasma meleagridis (MM) RSA
  • Salmonella pullorum (SP) RSA
  • Newcastle Disease Virus (NDV) ELISA
  • Avian Rhinotracheitis Virus (ART) ELISA
  • Infectious Bronchitis Virus (IBV) ELISA
  • Ornithobacter rhinotrachaele (ORT) ELISA
  • Chick Anaemia Virus (CAV) ELISA
  • Infectious Bursal Disease (Gumboro IBD) ELISA

How many samples are required per flock?

For most flock 20 individual blood samples will be sufficient but if for Poultry Health Scheme or for export purposes 60 bloods per houses will often be indicated.
