"Sometimes the most important finding is the absence of an expected response." What happens when a patient's lab work looks deceptively normal, even as they are getting sicker? Join us for the case of Libby, a Great Dane whose pneumonia was apparently improving on x-rays, yet she was mysteriously deteriorating, with recurrent vomiting and lethargy. The pivotal clue wasn't an abnormality on her CBC, but rather the glaring absence of one.

In this episode of Tails From the Lab, Drs. Holly Brown and Brad Ryan unravel a case where the lack of a classic stress leukogram in a critically ill dog pointed toward a hidden diagnosis. Libby’s journey from aspiration pneumonia to a life-changing discovery of atypical Addison's disease highlights how looking for what's missing can be the key to solving the most confusing medical mysteries.

Listen now to discover:

• Why the absence of an expected stress leukogram in a sick dog should be a red flag for clinicians
• How hypoadrenocorticism can be missed when it presents without classic electrolyte abnormalities
• The importance of integrating all diagnostic data, including labwork and imaging studies, for more accurate diagnoses and appropriate care
