Lateral tail vein blood collection is used in mice, rats, and gerbils, but not in which species?

• A. Hamsters
• B. Mice
• C. Rats
• D. Gerbils

Answer: (A)

Access to superficial tail veins varies by species, influencing which venipuncture sites are reliable. Mice, rats, and gerbils have lateral tail veins that run close to the surface and are easy to access with warming and gentle restraint, making small-volume blood collection from the tail straightforward. Hamsters, on the other hand, typically have tails that are shorter and less conducive to visible, easily punctured lateral veins, so this approach is not commonly used. For hamsters, researchers usually rely on alternative sites such as the saphenous vein or other approved methods.
