| pubmed-article:939698 | pubmed:abstractText | In the search of a fast and simple laboratory test for the diagnosis of neonatal septicemia the blood pictures of 29 cases of septicemia were compared with normal values derived from 390 healthy newborns. In each case the leucocyte count, the neutrophil count, the band count and its percentage, the ratio of band forms to segmented neutrophils and the platelet count were analysed in the blood smear taken on the day of clinical suspicion of septicemia. The leucocyte count, the neutrophil count and the band count are within the pathological range in 70% of the cases. The percentage of band forms and the ratio of bands forms to segmented neutrophils are, with one exception, always abnormally elevated. Thrombocytopenia is present in only 60% of the cases. Among the different criteria the percentage of band forms is evidently the most practical and most significant one. Considering our normal values, the pathological range for this percentage is above 20% on the first day of life, above 15% on the second day and above 8% from the third day on. | lld:pubmed |
