Repeated Blood Collection from Tail Vein of Non-Anesthetized Rats with a Vacuum Blood Collection System

Overview

This article presents a simple tail vein blood sampling method in non-anesthetized rats using a vacuum extraction tube system. This technique minimizes direct blood exposure and facilitates multiple samples from a single venipuncture.

Purpose of Study

• To develop a reliable blood sampling technique in non-anesthetized rats.
• To evaluate the efficiency and success rate of the method.
• To minimize stress and risk of contamination during blood collection.

Methods Used

• Rats were restrained and prepared for blood sampling.
• The tail was cleaned and blood vessels were dilated.
• A butterfly needle was used to collect blood into vacuum tubes.
• Success rates were compared between trained and beginner groups.

Main Results

• The success rate was 95% for experienced users and 90% for beginners.
• Sampling duration was shorter for the experienced group.
• The method allowed for sufficient blood volume collection.
• Minimal stress was reported for the animals during the procedure.

Conclusions

• This blood sampling technique is efficient and easy to learn.
