Which abbreviation is commonly used to refer to the capillary refill time?

The abbreviation used to refer to capillary refill time is CRT. This term is critical in veterinary medicine as it is a quick test used to assess circulatory efficiency and blood perfusion. It measures how quickly color returns to a mucous membrane after pressure is applied, which can help indicate the animal's hydration status and overall cardiovascular health.

In contrast, TPR stands for temperature, pulse, and respiration, which are vital signs, comprehensive measures of an animal's health but do not specifically correlate to capillary refill time. UA refers to urinalysis, a lab test analyzing the composition of urine, and does not relate to the test for capillary refill time. Dx is shorthand for diagnosis, referring to identifying a disease or condition, which is distinctly different from the measurement of CRT. Thus, CRT precisely denotes capillary refill time, making it the correct choice in this context.
