Preterm blood counts vary with sampling site.
In preterm babies both haemoglobin and total neutrophil count values from capillary sites are significantly and variably higher than those from simultaneous arterial samples. Comparing simultaneous venous and arterial samples, the mean haemoglobin was slightly higher but the total neutrophil counts were similar.
