Morales 1 Giannina Morales February 2, 2009 Weekly Lab Report – Determining Hematocrit Topic under discussion: The topic was to determine pack cell volume. The expected results are a range of 47 greater or equal to for males and 38 greater or equal to for females. Design of experiment or demonstration: The subject obtained a heparinized capillary tube, capillary tube sealer, a lancet, and alcohol swabs. The subject cleansed the finger and used the lancet to pierce the finger until the heparinized tube was full enough of the blood that was going to be used for the demonstration. The tube was then plugged using the capillary tube sealer. The tubes were then placed in the in the grooves of the microhematocrit centrifuge machine. The machine was then sealed. The heparinized tubes were then placed in the machine to spin for four minutes.

As the tube spun, the red blood cells went to the bottom of the tube, the white blood cells covered RBCs with a thin layer called the Buffy coat, and the liquid plasma was at the top. The height of the red cells is measured as a percent of the total blood column with the Critocaps card. The higher number of red cells, the higher the Hematocrit. The expected result is that the subject falls in normal range. Morales 2 Conclusions: After determining the percentage the tube that was used had. the conclusion was made that the subject had a normal range ....
