Packed cell volume PCV Lab: 4 Assistant Lecturer Ahmed Makki PCV: is the measure of the relative percentage of red blood in a given volume of whole blood. This test is used to diagnose anemia (a decrease in red blood cells), and polycythemia (an increase of red blood cells). This test is included in the complete blood count (CBC). Introduction Material Good blood sample Hematocrit capillary tube Sealing material Micro centrifuge Hematocrit reader 1. Clean the finger by spirit and give a deep prick with a sterile lancet. 2. Enter the blood in the capillary tube to ¾ of its length. 3. Seal the cap tube. 4. Centrifuge for 4-5 min at 11000 rpm. 5. Determine the value by hematocrit reader. procedure 3 about 18% 4 2 1 5 Normal hematocrit for adult females: 37- 47% Normal hematocrit for adult males: 42- 52% Normal hematocrit for children: 36-44% Normal value PCV increase in : ❖Polycythemia ❖Dehydration (low in fluid in the blood ) ❖Lung disease ❖Some heart disease PCV decrease in: ❖Pregnancy ❖Anemia ❖Low in minerals like iron ❖Kidney diseases THANK YOU
