Ordering Labs For Uveitis: Downloadable Cheat Sheet
So your patient has uveitis: what’s next?
Finding the cause requires a little detective work, particularly in terms of knowing which labs to order based on the patient’s history and your examination and systems review. In first-time cases of unilateral, mild uveitis, eyecare practitioners typically do not order labs.
When ordering labs, focus on the etiology you believe is behind your patient’s problem based on a thorough case history of ocular and systemic symptoms as well as your clinical exam findings.
Here’s a quick guide to follow on what labs to order next time you have a patient with uveitis.
