Recommendations for sampling and dispatching of blood samples for testing of EQUINE NOTIFIABLE DISEASES

General recommendations:

To avoid any delays, please strictly follow these recommendations for sampling.


  • Use proper vacutainer tubes from CVRL or vacutainer from Becton Dickinson UK Cat. No. 368430. Other tube types do not fit in our centrifuges.
  • After taking blood from the jugular vein, the blood in the tubes has to settle.
  • Keep the tubes at room temperature for at least 2 hours. During this time, the serum will separate from the blood clot. Do not freeze or refrigerate the blood during this period.
  • After the serum has separated from the clot, please take the following steps:
    1. If the tubes can reach CVRL within 2 to 4 hours after the initial settling of the blood, send them without centrifugation and without decanting the serum into new tubes. However, the tubes must be kept at +4°C (not frozen) and reach CVRL in a cool container.
    2. If the blood has to be sent to CVRL by courier, the vacutainer tubes that have been kept at room temperature must be centrifuged, and the serum (without any traces of blood) poured into new tubes. To avoid leakage, the tubes should be made of plastic and should be tightly sealed with a lid and paraffin tape. The serum must reach CVRL frozen!
    3. Please submit at least 7 ml of serum.

A completed requisition form signed by an acknowledged veterinarian must accompany all despatched samples. The forms can be obtained from CVRL or downloaded from this site.
