The study assessed detection rates of true-positive cultures, contamination rates (false positives), and incidence of culture-negative sepsis.<\/jats:p>\n                  <jats:p>A total of 336 infants had UCBCs performed, with 223 undergoing concomitant NBCs. Positive culture rates were similar: Four UCBCs (1.2%) and three NBCs (1.3%) were positive. UCBC had two contaminants (0.6%) while NBC had one (0.45%). One infant had both cultures positive for Escherichia coli. No infants required prolonged antibiotics for culture-negative sepsis.<\/jats:p>\n                  <jats:p>The contamination rate of UCBC was extremely low in the cohort of infants at high risk for EONS. Our protocol and collection technique may serve as a model for others aiming to reduce contamination rates. While NBC can be positive despite a negative UCBC, and vice versa, obtaining both UCBC and NBC can improve the sensitivity of EONS diagnosis and help minimize prolonged antibiotic use in cases of culture-negative sepsis. UCBC demonstrated a low contamination rate and comparable diagnostic yield to NBC. UCBC may be considered a reliable alternative or adjunct to NBC in the evaluation and management of EONS.<\/jats:p>","DOI":"10.1055\/a-2741-2727","type":"journal-article","created":{"date-parts":[[2025,11,8]],"date-time":"2025-11-08T23:30:22Z","timestamp":1762644622000},"page":"1244-1249","source":"Crossref","is-referenced-by-count":0,"title":["Umbilical
