Which statement about dehydration testing is correct?

• A. Skin pinch test is a standard method to assess hydration.
• B. Skin pinch test is an unreliable test and should be ignored.
• C. Only blood tests can determine dehydration.
• D. Hydration cannot be estimated in the field.

Answer: (A)

Assessing dehydration in the field relies on quick, hands-on signs, and the skin pinch test is a standard method because it directly tests skin turgor, which reflects the animal’s hydration status. To perform it, pinch a small area of loose skin (often the scruff or lower back) and release. If the skin snaps back immediately, hydration is likely adequate. If the skin tents and returns slowly, dehydration is present and often correlates with greater fluid loss. This method is widely taught in wildlife rehab because it provides a rapid, noninvasive read that helps triage and guide initial treatment in the field. While not perfect, the skin pinch test remains a cornerstone of field assessment and should be used alongside other signs such as mucous membrane moisture, capillary refill time, eye appearance, body condition, and behavior. Blood tests can offer additional information, but dehydration can be estimated without them, and hydration status cannot be determined solely by bloodwork in all field situations. Hydration can indeed be estimated in the field using these clinical signs.
