Most labs testing children for cardiac troponin lack pediatric reference ranges, survey finds
Medical Xpress reports on an IFCC survey of laboratory specialists and clinicians from 48 countries, published in Clinical Chemistry and Laboratory Medicine. Of eligible respondents, 58.5% offered in-house cardiac troponin testing, but 65.5% of these lacked child-specific reference intervals and often relied on manufacturer-provided adult ranges. Where pediatric cutoffs existed, they varied. The researchers propose condition-specific benchmarks rather than one generic range.
Why it matters: Relevant to clinicians and laboratory staff who order or interpret cardiac troponin tests in children, and to those who refer pediatric cardiac patients.
