=== NIH Classification ===

* '''<span style="color:#ff0000">Category I: acute bacterial prostatitis</span>'''
* '''<span style="color:#ff0000">Category II: chronic bacterial prostatitis</span>'''
* '''<span style="color:#ff0000">Category III:</span>''' presence of '''<span style="color:#ff0000">pain in the absence of bacteria</span>''' (detected by standard microbiological methodology)
** '''<span style="color:#ff0000">Subtypes (2)</span>'''
*** '''<span style="color:#ff0000">IIIA (inflammatory CP/CPPS):</span>''' excessive leukocytes in the expressed-prostatic secretion (EPS) or post–prostatic massage urine or semen
*** '''<span style="color:#ff0000">IIIB (non-inflammatory CP/CPPS):</span>''' no significant leukocytes in similar specimens
*** No validated cutoff point for the level of WBCs per high-power field that is required to differentiate an inflammatory from a non-inflammatory CP/CPPS.
**** Consensus appears to favor '''5-10 WBCs/HPF in EPS as the upper level of normal inflammatory cells in the EPS;''' this can fluctuate over time and with the frequency of ejaculation
* '''<span style="color:#ff0000">Category IV: asymptomatic prostatitis;</span> significant leukocytes (or bacteria or both)''' in prostate specific specimens (EPS, semen, and tissue biopsy specimens) '''in the absence of pain'''
