A study has been carried out using Microstix (Ames Co.) in 100 hospital patients to assess the role of these “stix” in the diagnosis of bacteriuria. The culture areas of the stix for total infections and Gram‐negative infections gave a detection rate of 85% and 100% respectively when compared with standard bacteriological methods. Looking at all those urines with > 10 4 organisms/ml on the microstix, the detection rate was increased to 100% for both test strips but the false‐positive rate became 36% for the combined strip and 25% for the Gram‐negative strip. The nitrite test gave no false‐positive results but failed to detect 66% of positive cultures.
