Conditions
Brief summary
This study aims to assess the agreement between the laboratory measurement of blood haemoglobin and that obtained from two devices which measure haemoglobin at the patients bedside thus providing rapid results which can be used to guide management. One is the HemoCue 'Registered Trademark' device measures Hb concentration from very small amounts of blood either from a finger prick or the veins, the other is the Masimo Pronto-7 'Registered Trademark' spectrophotometry device measures Hb concentration non-invasively using light sensors on a finger probe similar to those used to measure the amount of oxygen in the blood.
Interventions
Measurement of haemoglobin concentration in pregnant women assessed for each women at a single time point between 20 weeks gestation and the immediate postpartum period.
In each women three measurement techniques will be used (i) automated laboratory, (ii) non-invasive spectrophotometry (Pronto 7 Pulse CO- Oximeter, Masimo Corp, Irvine USA) & (iii) invasive photometry absorbance (HemoCue, Angelholm, Sweden).
Techniques (i) & (iii) will use a venous blood sample, whilst (ii) uses a transcutane
