Urinalysis is an emerging method for monitoring the health and energy balance of wild primates. Here, we report the first urinalysis of wild gibbons. We used multi‐reagent test strips to monitor the health status of 52 individual white‐handed gibbons ( Hylobates lar ) inhabiting Khao Yai National Park, Thailand. Most urinary reference values were within normal ranges; however, regardless of age‐ and sex‐class or monthly fruit productivity, we found unexpectedly high rates of urinary leukocytes (50% and 90% of individuals in 2001–2003 and 2006, respectively). In contrast to previous studies of African apes, this finding is coupled with the near absence of urinary nitrites, demonstrating pervasive levels of sterile pyuria. This result is the first reported case of sterile pyuria in a population of wild primates. The etiology of human sterile pyuria is diverse, but in all cases it is diagnostic of systemic inflammation. We discuss the potential causes of sterile pyuria in the gibbons of Khao Yai. Am. J. Primatol. 71:880–883, 2009. © 2009 Wiley‐Liss, Inc.
