The Claim
Noninvasive arterial catheter sampling provides a more accurate and reproducible reference for measuring murine circulatory fluxes compared to tail snip-based methods, thereby reducing measurement variability and eliminating stress- and site-induced artifacts that inflate flux estimates.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Using a tiny tube in a mouse’s artery to measure blood flow is more reliable than cutting its tail, because tail cutting stresses the mouse and gives wrong numbers.

What the research says
1 studyStudy: Impact of acute stress on murine metabolomics and metabolic flux
Scientists found that taking blood from a mouse’s tail makes it stressed and changes the blood chemistry, making measurements wrong. But taking blood from an artery in the body doesn’t stress the mouse, so the numbers are more accurate.
