Anemia and iron deficiency are the most frequent nutritional problems on the worldwide scale. Haemoglobin, the\niron containing metalloprotein in the red blood cells, transports oxygen from the lungs to the rest of the body, where\nit releases its load of the oxygen. Depletion of iron concentration leads to inhibition of haemoglobin synthesis\ncausing iron deficiency anemia. Mainly women are at the risk of developing iron deficiency. Taking this into\nconsideration estimation of iron concentration and haemoglobin level from blood samples of 96 working women\nvolunteers from various age groups is carried out. Haemoglobin level estimated by using CMG method and iron\nconcentration determined by atomic absorption spectroscopy technique. In the samples iron concentration and\nhaemoglobin level are found to be in the range of 119 to 970 ppm and 8.8 to 18.7 g/dL respectively. 44 cases\nshowed haemoglobin level lower than the normal range indicating anemic condition. On the other hand iron\nconcentration and haemoglobin level in 10 cases was found to be in the normal range. 37 cases showed iron\nconcentration lower than normal range though haemoglobin level was within normal reference range. Iron concentration and haemoglobin level in remaining 5 cases was found to be more than normal range.

What are instrumental techniques?. Modern chemists use a range of instruments to analyse and identify substances. Most produce quantitative data, which requires expert interpretation.
