The reason behind using the blood group O negative in the patient, even before knowing his actual blood group. Introduction: The blood forms an important part of the body. It constitutes the circulatory system that is important to deliver nutrients and oxygen to the various body parts. The blood is composed of formed elements (45%) and plasma (55%). The formed elements contain leukocytes (white blood cells), erythrocytes (red blood cells), and platelets. The plasma contains various dissolved ions, proteins, metabolic wastes, and gases. In case of heavy blood loss, the patient is infused with packed red blood cells in order to compensate for the lost blood. Blood typing or blood matching is important before transfusion because wrong blood type can cause transfusion reactions in the patient.

A sample of blood was taken from the above individual and prepared for haemoglobin analysis. However, when water was added the cells did not lyse and looked normal in size and shape. The technician suspected that they had may have made an error in the protocol – what is the most likely explanation? The cell membranes are more resistant than normal. An isotonic solution had been added instead of water. A solution of 0.1 M NaCl had been added instead of water. Not enough water had been added to the red blood cell pellet. The man had sickle-cell anaemia.

With reference to their absorption spectra of the oxy haemoglobin intact line) and deoxyhemoglobin (broken line) shown in Figure 2 below, how would you best explain the reason why there are differences in the major peaks of the spectra? Figure 2. SPECTRA OF OXYGENATED AND DEOXYGENATED HAEMOGLOBIN OBTAINED WITH THE RECORDING SPECTROPHOTOMETER 1.4 Abs < 0.8 06 0.4 400 420 440 460 480 500 520 540 560 580 600 nm 1. The difference in the spectra is due to a pH change in the deoxy-haemoglobin due to uptake of CO2- 2. There is more oxygen-carrying plasma in the oxy-haemoglobin sample. 3. The change in Mr due to oxygen binding causes the oxy haemoglobin to have a higher absorbance peak. 4. Oxy-haemoglobin is contaminated by carbaminohemoglobin, and therefore has a higher absorbance peak 5. Oxy-haemoglobin absorbs more light of blue wavelengths and less of red wavelengths than deoxy-haemoglobin
