Urinalysis - The Carter Center

• Sometimes because of predominance of neutrophils and the
occurrence of bacterial cell together with polymorphonuclear cells,
WBCs are called pus cells.
• WBCs (pus cells) may be seen in clumps.
• It is also possible to see single irregular nuclei and small round lobed
nuclei in the WBCs, that are seen in the urine sediment
Clinical implication: increased number of leukocyte urine are seen in
case of:
• Urinary tract infection
• All renal disease
• Bladder tumor
• Cystitis
• Prostates
• Acute or chronic bacterial infection such as renal tuberculosis,
temporarily increased number of leukocytes are also seen during:
- Fever, and
- After strenuous exercise
How to report the result:
- After observing the distribution of leukocytes under 40x objective, at
least 10 fields of microscope, it is possible to report as : 0-5
leukocytes / HPF, 20-39 leukocytes / HPF etc, that is by counting the
total leukocytes in 10 HPF and divide by 10.
Or, When 0-5 leukocytes / HPF are seen............. normal
5-10 leukocytes / HPF are seen...................... few leukocytes / HPF
10-20 leukocytes/HPF are seen…...........moderate leukocytes/ HPF
20-30 leukocytes /HPF are seen …............... many leukocytes / HPF
Above 30 leukocytes / HPF / are seen ……… full/field
