A further sample of blood was taken from the above individual and prepared for haemoglobin analysis. To 18 mls of blood, 2 mls of anticoagulant were added and 5 mls of this sample was centrifuged and a 2.6 ml pellet of red blood cells obtained. 10 mls of water were added and mixed to lyse the cells before a further centrifugation to remove cell membranes from the sample. 1 ml of this sample was further diluted by the addition of 5 mls of water to provide a stock sample of haemoglobin. What was the final dilution factor for this haemoglobin stock solution? O 1.16.76 QUESTION 3 О 2.1.67 О 3.1247 O 4.1.51 O 5.61.89
