- Summary: A laboratory haematology analyser is the gold standard for measuring haemoglobin concentration but has disadvantages, especially in neonates. This study compared alternative blood‐sparing and non‐invasive methods of haemoglobin concentration measurement with the gold standard. Haemoglobin concentrations were measured using a laboratory haematology analyser (reference method), blood gas analyser, HemoCue ® using venous and capillary blood samples and a newly developed non‐invasive sensor for neonates < 3 kg. A total of 63 measurements were performed. Body weight (2190 (1820–2520 [967–4450]) g) and haemoglobin concentration (12.3 (10.6–15.2 [8.2–20.5]) g.dl −1 ) varied widely. Bias/limits of agreement between the alternative methods and reference method were −0.1/−1.2 to 1.0 g.dl −1 (blood gas analyser), −0.4/−1.8 to 1.1 g.dl −1 (HemoCue, venous blood), 0.7/−1.9 to 3.2 g.dl −1 (HemoCue, capillary blood) and −1.2/−4.3 to 2 g.dl −1 (non‐invasive haemoglobin measurement). Perfusion index, body weight and fetal haemoglobin concentration did not affect the accuracy of the alternative measurement methods, and these were successfully applied in term and preterm infants. However, the accuracies of non‐invasive haemoglobin measurement and HemoCue of capillary blood especially lacked sufficient agreement with that of the reference method to recommend these methods for clinical decision making. 개요: 혈구분석기를 통한 실험분석은 혈색소 농도 측정에 있어서 표준이 되는 검사이나 단점을 가지고 있으며, 이는 특히 신생 아에서 더 두드러진다. 본Summary: A laboratory haematology analyser is the gold standard for measuring haemoglobin concentration but has disadvantages, especially in neonates.
