The Coulter STKS was evaluated in a children's hospital, in order to (a) compare the WBC differential given by the instrument to a 400 cell visual differential (reference method); (b) evaluate the sensitivity and specificity of the alarm system, and (c) provide data concerning the use and interpretation of results in children. 653 blood samples were collected. The Coulter STKS results were studied in 523 patients having no morphological abnormalities in the blood smears, separated into subgroups according to the presence of STKS alarms and according to age. The results were found accurate both in STKS negative and STKS positive patients (i.e., those with alarms: 'Blasts', Imm Gran 2, Variant Lymph, NRBC, review slide). Negative STKS results had the same accuracy in all age groups, except in neonates where slide review must be systematically performed. The instrument exhibited a good sensitivity of the suspect flags studied (91.4%), with a lower specificity (72%) reflecting the number of false positive results found in our group, probably due to the cytological features particular to children. However, it was shown that the numerical results given by the Coulter STKS in positive patients could be taken into account, provided that a scan of the blood smear was negative for morphological WBC abnormalities.
