The VETSCAN HM5 is a hematology analyzer that reports a full, 3-part CBC differential with 22-parameters in less than 3 minutes using as little as 30ul of blood for certain species (pig, goat, sheep, rat, ferret, mouse, guinea pig, rabbit, primate).
If you are using low volume of blood, less than 100ul, the sample needs to be brought to the core in raised bottom tubes. (BD Microtainer Tubes with EDTA ref#365974 or similar). If you have 100ul plus of blood then any micro tube with EDTA will work.
Refer to the blood sample handling best practices below for proper blood collection methods.
