How do you collect blood from a hamster?
Blood is collected by capillary action into a haematocrit tube or passively into a tube. Blood flow can be stopped by gentle finger pressure over the puncture site, or simple relaxation of the operator’s grip on the animal’s leg. Animals should not be returned to their cage before the blood flow has stopped.
Which method is not used to obtain blood from rodents?
Microsampling is not the preferred extraction method when taking samples from rodents that have tumors or when technical replicates are required. Also, it’s difficult to control the bleed rate during sampling, which can result in more blood being taken than can be used in testing.
How do animals get blood samples?
The animal is restrained manually or using a suitable animal restrainer. Hind leg is immobilized and slight pressure may be applied gently above the knee joint. The vein is punctured using a 20G needle and enough volume of blood is collected with a capillary tube or a syringe with a needle.
What is retro-orbital bleeding?
In retrobulbar bleeding (RBB), also known as retro-orbital bleeding, a capillary tube is used to disrupt the retrobulbar venous sinus located behind the eye.

How much blood can you draw from a rat?
Single sample: Without fluid replacement, the maximum blood volume which can be safely removed for a one-time sample is 10% of the total blood volume or 5.5-7 ml/kg. With fluid replacement (LRS or sterile physiologic saline), up to 15% of the total blood volume or approximately 8.3-10.5 ml/kg can be removed.
How do vets take blood samples?
Most blood samples are taken from the jugular vein in the neck. This vein is large enough to provide a good sample and allows us to collect the blood as quickly as possible. This is important as blood will start to clot if it is not collected swiftly and this can affect the results.
Which vein is usually saved for catheters in small animals?
The cephalic vein is often the most common and easiest location to use for catheterization.
What is retro-orbital?
