Detection of urinary leukocytes by chemstrip-l.
Chemstrip-L was evaluated in 300 patients for its ability to detect leukocytes in urine. The strip reacts to esterases that are present in leukocytes and not in normal urine. When the chamber count is used as a standard Chemstrip-L has a sensitivity of 95.3 per cent and a specificity of 98 per cent. A minimal reaction time of 15 minutes was confirmed. No discrepancy could be related directly to drug interference.
