BLOOD COLLECTION: THE MACAQUE
General laboratory animal guidelines include:
  • Too much blood collected at any one time may cause hypovolemic shock, physiological stress and even death. If smaller volumes are collected too frequently, anemia may result.
  • As a general rule, 10% of the total blood volume can be collected at one time every 2-4 weeks. Or 1% at intervals of 24 hours or more. Total blood volume can be calculated as approximately 7.5% of body weight.
  • The estimated volume at exsanguination is approximately half of the total blood volume.

EXAMPLE:

Average Adult Weight Total Blood Volume Maximum Sample in mls 2-4 Weeks Estimated Exsanguination Volume
6 kg 450 ml 45 ml 225 ml
