Question
The Unknown blood sample above has a hemoglobin concentration of a. 6g/dl b. 12 g/dl c. 22g/dl d. 30 g/dl e. none of these A blood sample was placed in a capillary tube and spun In a centrifuge. Upon observation, occupied 20mm and the total volume of blood and plasma occupied a distance of 47 mm. this patient is a. 30% b. 39.5% c. 42.5% d. 2.35% In order to calculate the Mean Corpuscular Hemoglobin Concentration, the following a. Hematocrit and red blood cell counts b. hemoglobin concentration and hematocrit c. hemoglobin concentration and red blood cell counts d. none of theseExplanation / Answer
37) a) Hematocrit
Hematocrit is the percentage of packed red cells in a whole blood sample.
38) C) Option 22g/ml
With help of standard curve we will be measuring the absorbance of concentration and plotting the graph with concentration on x axis and absorbance on y axis when we check for absorbance of unknown sample it will be around 22 gm/ml.
39) Option 42.5%
Hematocrit is calculated by formula by RBC occupied area by distance travelled by plasma and then multiplied by 100 which will be 20/47x100 and it will be 42.5%
40) Hemoglobin concentration and Red Blood Cells count
Mean corpuscular hemoglobin concentration, a measure of the concentration of hemoglobin in a given volume of packed red blood cells. Calculated by dividing the hemoglobin by the hematocrit for which hemoglobin and RBC cell concentration should be known
